Trelleborg Supports Engineers Developing Drug-eluting Devices

Trelleborg Supports Engineers Developing Drug-eluting Devices

Trelleborg Sealing Solutions releases two whitepapers focused on the combination of silicone with Active Pharmaceutical Ingredients (API) that will support healthcare & medical device engineers and designers involved in the development of drug-eluting devices.

Drew Gaillard, Global Director Healthcare & Medical for Trelleborg Sealing Solutions, says: “The Healthcare market is driven by trends such as an aging population, increasing chronic disease, and global healthcare concerns related to obesity, diabetes and infectious diseases.

HM Whitepaper Drug Eluting Devices

With these trends comes other struggles for the medical community, such as an increase in catheter associated infections or the challenge of ensuring patient compliance with their medications. These trends and challenges have in turn led to the rapid innovation in drug device combination products, in particular those that elute regular, controlled doses of drugs precisely and consistently to a treatment area.”

Drug-eluting devices can be produced in and by a variety of materials and processes. One of the most successful materials in the design and production of combination products, in particular implantable ones, is silicone.

Gaillard continues: “Trelleborg Sealing Solutions is at the forefront of silicone drug-eluting product innovation and has studied the different methods of combining silicone with an API. The results of testing on the immersion method are now available to engineers and designers working in the healthcare & medical field.”

In the whitepaper Supporting the Advancement of Drug-Eluting Devices, two methods of adding Active Pharmaceutical Ingredients (API) to silicone, the addition of API to raw silicone and the impregnation of vulcanized silicone with API by immersion, are discussed.

The traditional method of adding API to uncured silicone is proven and effective. However, it is limited to API that are resistant to a vulcanization process and exposure to heat. A newer method of impregnation of vulcanized silicone by API, potentially broadens the APIs that can be used in drug-eluting silicone devices. This whitepaper presents test results that prove the effectiveness of this method, potentially opening drug-eluting devices to delivery of a wider range of API.

The second whitepaper, Fighting Hospital Acquired Infection, focuses on Healthcare-Associated Infections (HAI). Although combatting hospital-acquired infections has been a focus for the medical community, they still remain a significant issue. In particular, catheter-associated infections are difficult to prevent due to a catheter’s inherent positioning: part in and part out of the body.

Silicone is often used for the catheter tubes and though the material is biocompatible and biostable, it is not immune to bacterial colonization. Techniques exist that can reduce this colonization including coating, addition of antibiotic API to raw silicone and the impregnation of vulcanized silicone with API through immersion. In this whitepaper the three techniques are evaluated and Trelleborg shares its results from an effectiveness study of the impregnation methodology.

The two whitepapers, Supporting the Advancement of Drug-Eluting Devices and Fighting Hospital Acquired Infection, are the latest additions to the Trelleborg Sealing Solutions technical area that contains valuable resources for the engineer and designer.

Nano Scale Seal-Glide Coating

Nano Scale Seal-Glide Coating

Seal-Glide®, an innovative surface treatment from Trelleborg Sealing Solutions, significantly improves friction and stick-slip properties of elastomer seals while having little or no effect on the performance of the compounds the seals are made from. The coating is just a few hundred nanometers, ten to 50 times less than typical coating thicknesses. Even though it is so thin, the coating significantly reduces the friction coefficient of elastomer seals and improves their stick-slip properties considerably, facilitating effective automated assembly.

Nano Scale Seal-Glide Coating

Seal-Glide® is suited for coating classic O-Rings and complex molded parts for a wide range of applications and is available in two versions: Seal-Glide® Nano for automotive and industrial uses and Seal-Glide® Medical. Typically Seal-Glide® coatings are less than 450 nanometers. It therefore imparts the benefits of a surface coating, without affecting the bulk properties of the seals. As a result, the original elastic properties of the elastomers are virtually unaltered but the seals have a higher service life due to reduced wear when in motion or on start-up.

Andreas Schmiedel, Technical Manager for Healthcare and Medical in Europe at Trelleborg Sealing Solutions, says: “The Seal-Glide® Medical coating is ideal for use in healthcare and medical applications as the new process has a very high level of stability. This makes it resistant against sterilization with gamma radiation, ethylene oxide and hot steam, which is essential for the multiple use of medical devices, valves or syringes.

“To this end, the coating process satisfies the strict requirements for medical, bio-technology and pharmaceutical applications as prescribed by the authorities such as the American FDA (Food and Drug Administration) or European standards such as DIN EN ISO 10993 for the biological evaluation of medical devices.”

In automotive or industrial applications, Seal-Glide® Nano gives distinct advantages in high volume automated assembly lines.

Gordon Micallef, Operations Director at Trelleborg Sealing Solutions in Malta, where Seal-Glide® Nano was developed, says: “The strong surface tackiness of elastomer seals is an inherent property, which can cause issues such as the creation of high assembly forces, disruptions in automatic assembly lines as well as reduced performance in dynamic applications.

“On many assembly lines, overall speed is limited by the elastomer parts feed rate. Due to the reduction in co-efficient of friction, the use of the Seal-Glide® Nano coating will result in significant efficiency gains, by considerably improving the feed rate in automatic assembly lines.”

Elastomers without a surface treatment tend to stick, either to each other during automatic assembly or to counter surfaces in dynamic use. A particular issue is after periods of rest, when due to an elastomer’s inherent stickiness, there can be a stick-slip-effect. In this, the elastomer seal sticks to its counterpart and when moved elastomer is pulled off the seal reducing seal life. In addition, extra energy is required to move the seal from a stationary position.

This stick-slip effect can be minimized or even virtually eradicated through effective surface treatment of a seal. This is also important in healthcare and medical applications.

Schmiedel continues: “When coated, O-Rings or complex molded parts can be installed more easily and securely in components due to better separation of the seals. Using the friction-reducing coating, the components can be assembled smoothly and without damage so that the entire assembly process is completed simply and securely. Feed issues are minimized, reducing the probability of production stops.”

Another advantage of Seal-Glide® is that due to its thinness, the coating has a high level of transparency and does not cover the original color of the elastomer. The color of seals can play a central role in assembly. O-Rings are mostly black, but are often dyed in order to visually highlight differences in composition, diameter, thickness or positioning within a component. With our innovative coating, this color coding is retained, even after the coating.

Seal-Glide® is suitable for many types of elastomer and thermoplastic seal material types. These include LSR (Liquid Silicone Rubber), Ethylene Propylene Diene Monomer Rubber (EPDM), Fluorocarbon (FKM), Fluorosilicone (FVMQ), Nitrile Butadine rubber (NBR), Hydrogenated Nitrile Butadiene Rubber (HNBR), Ethylene Acrylate Rubber (AEM), and silicone rubber (VMQ) as well as thermoplastic polyurethane (TPU).



Trelleborg Sealing Solutions unveils a pioneering product that could “radically improve the reliability” of rotary wing aircraft.


The Turcon® Varilip® PDR RT rotary shaft seal, which has already been proven to out perform other similar seal products, was developed to meet the ever-growing demand to provide seal integrity at increasingly higher rotational wing speeds.

Torben Andersen, Trelleborg Sealing Solutions Director of Aerospace, said: “This project started several years ago, when we wanted to find a seal that would provide a better performance at very high speeds, specifically for rotary wing aircraft.

“We knew that at high surface speeds, ensuring that essential lubrication is maintained was a major challenge and any leakage would compromise the operation of the aircraft. That’s why designing a seal that out performs anything that’s currently out there was so vital.”

During the development of the Turcon® Varilip® PDR RT rotary shaft seal, Trelleborg designed and commissioned bespoke high speed test equipment capable of running at speeds of up to 24,000 rpm and a test programme that closely followed the way rotary wing aircraft gearboxes work. This allowed developers to ensure that the seal met highly demanding application requirements. The team experimented with a number of different lip materials, marrying them to various seal designs and investigating the best lip geometries and lip features to select the correct profile and material.

Torben added: “This is a breakthrough. We’ve developed a process that facilitates a seal with less torque, friction and heat to reduce maintenance; one that will radically improve the reliability and boost the performance of rotary wing aircrafts.

“Though initially designed for this specific application, the work we’ve done shows that it also lends itself to other applications that require high speed rotary performance. We’re already generating interest from designers of electromechanical actuators and from a wide range of other market segments.

“For many years there has been a standard version of the Turcon® Varilip® PDR – but this new seal operates effectively with less power and is therefore more efficient. We’ve optimised the design so it can run on a range of surface finishes and coatings, including ceramics.”

Using Trelleborg’s bespoke testing equipment, the Turcon® Varilip® PDR RT rotary shaft seal has undergone more than 20,000 hours of endurance testing with latest designs operating at 3,500 hours leak free.

These systems, with complex configurations of seals, are fundamental to the function of robotic equipment. Solutions are required to operate 24-7 with the minimum of downtime, either planned or unplanned. Specific sealing solutions are required that demonstrate outstanding friction capabilities to extend seal life, minimize wear and facilitate smooth and constant movement.

Yoichi Higuchi, who heads up the Robotics lead group at Trelleborg Sealing Solutions, says: “Robots are revolutionizing the way that our products are manufactured, how we look after our homes and procedures in hospitals, for instance. They are becoming critical to our everyday lives and the applications for high-tech appliances are increasing exponentially.

“The robotics market is expected to boom. According to Transparency Market Research the global market is likely to see growth of around 17% to reach revenues of 147 Billion by 2025. When you consider that every robot that has moving ‘arms’ needs a servomechanism, hydraulic or pneumatic system to control them, requirements for seals are going to be huge and continually become ever more challenging.

“In addition to increasing volume demands, there is a need for maximized performance. And ensuring this is becoming even tougher for component suppliers as robots become more sophisticated, size-optimized, faster, stronger and smarter.”

Trelleborg Sealing Solutions supplies seals to numerous types of robots, including robots for industrial, medical, construction, disaster recovery, probe, surveillance, household, entertainment, drone and personal mobility applications.

Trelleborg Seeks to Connect its Past with its Future at OTC 2018

Trelleborg is excited to start the celebration of 50 years of the Offshore Technology Conference (OTC) at this year’s exhibition and the Group’s 45 years of participation at the event. Trelleborg’s stand theme this year is ‘Going the Distance: Connecting our past to the future’, and it will launch a timeline that includes firsts from the oil & gas industry, OTC, and Trelleborg.

OTC 2018

On this journey through time, Trelleborg visits historical moments that can be looked back on to gain insights into what the future of the offshore industry could be and how it can be shaped for coming generations. Trelleborg is looking forward to more smart products incorporating the Internet of Things (IoT), digital service tools and an increase in the ease of doing business and communications for its customers and employees.

Trelleborg invites OTC attendees to visit its stand, number 3227, to share past, present and future industry moments that they think are important for the timeline, allowing them to take the opportunity to define industry moments! These moments can be from the visitors’ companies, a favorite memorable industry moment, perhaps the first time they attended OTC, or their thoughts on key developments for the future of the offshore industry.

Within the timeline, Trelleborg will demonstrate some of the ways in which its innovative solutions improve safety, optimize productivity, and help to retain competitiveness as barrel prices continue to recover. These include the following:

Drill Riser Augmented Designs

As an augmentation to traditional drill riser buoyancy modules that provide critical uplift to marine risers, Helically Grooved Buoyancy significantly reduces drag and flow-induced motion. Validation test results indicate that the performance is equivalent to fairings, but at a fraction of the total operational cost.

Antony Croston, Business Group Director with Trelleborg’s offshore operation in Houston, says: “We reached a major milestone last year when testing results revealed that, when using the patented helically grooved buoyancy design, vortex induced vibration is effectively eliminated in high currents, with the added bonus that drag loading on the riser is also reduced to a level comparable with fairings.

“For many years, fairings have been accepted as the best technical solution for drag and VIV reduction on drilling risers. Their use has come with an operational penalty in the form of increased running and retrieval time, as well as handling issues, especially in harsh weather. We now have an integral concept, which has been proven to match the performance of fairings, without any issues in drilling riser handling and running methodologies.”

Critical Customization of Seals

Eric Bucci, Trelleborg Sealing Solutions Segment Manager Oil & Gas Americas, says: “Maximizing the yield from wells is a high priority for operators. Therefore, accessing unconventional wells, those previously believed to be too deep for existing capabilities, is now being more frequently undertaken. This means processing technology must be able to withstand high fluid pressures while subjected to very high temperature conditions, often coined HPHT.”

Trelleborg Sealing Solutions will be highlighting a new customizable Metal End Cap (MEC) seal engineered for safety and reliability in critical static HPHT wellhead, tubing and casing hanger sealing environments. The metallic components within the seal are chemically bonded to the elastomer sealing element and provide a high level of extrusion resistance and metal-to-metal contact against the hardware. The elastomer sealing element also provides leak tightness against sub-optimal tubing surface finishes and it conforms to NORSOK, NACE, API and Total standards.

Bucci, continues: “We work with our customers to provide a great portfolio of materials and matching the best option to an application can optimize performance and safety. Experts will be on-stand at OTC to discuss visitors’ specific sealing applications.”

Commitment to Innovation in Hoses

Cryoline LNG hoses have been specially developed to address pressing infrastructure challenges in the LNG market. While LNG demand is growing, the cost of developing extensive and conventional transfer infrastructure may reduce or negate feasibility of power generation, terminal and bunkering projects. Infrastructure needs to move quickly to meet demand, and at the same time, ensure that projects are economically feasible, and sustainable in the long term.

Vincent Lagarrigue, Director of Trelleborg’s oil & marine hoses operations states, “Trelleborg cryogenic hoses can create turnkey projects that drastically reduce the capex and environmental impact of LNG import infrastructure. They also open up new locations to ship-to-shore and ship-to-ship transfer, even in challenging weather conditions. This technology was put to the test in October 2017, when it was used in the first sea launch of the Universal Transfer System (UTS), developed with Connect LNG and Gas Natural Fenosa. The success of this launch demonstrated the vast potential of floating cryogenic hoses for unlocking new infrastructure possibilities. These hoses use Trelleborg’s dual carcass design and integrated monitoring systems to minimize boil-off and ensure safety.

“Our Reeline hoses demonstrate how our commitment to innovation in oil transfer solutions underpins maximum operability, lifecycle and safety. Reeline hoses use Trelleborg’s unique nippleless hose technology to create a flexible bonded oil hose that is specially designed for reeling operations, increasing ease of installation, optimizing opex and freeing up valuable space on deck for offshore operations. They incorporate Trelleborg’s dual-carcass structure to ensure safety and long service life, even in the harshest conditions.”

Knowledge Sharing at OTC

Trelleborg is committed to sharing its knowledge with the industry and welcomes the opportunity to speak at industry events such as OTC. Sharing such knowledge is vital for the future of the industry because the discussions and presentations allow the industry and its community to learn from its mistakes and builds on its successes. This year, Trelleborg will be presenting three technical papers during the conference.

Vincent Lagarrigue will be presenting a technical paper titled “Re-Shaping LNG Transfer” on Monday April 30 at 14:00 in room 602 as part of the session on FLNG and Gas Monetization – Innovative Processing and Design.

Collin Gaskill, Product Development Engineer with Trelleborg’s offshore operation will be presenting two technical papers at the conference. The first is titled “VIV-Mitigating Buoyancy Module Performance Characterization Using Computational Fluid Dynamics” on Wednesday, May 2 at 09:30 in room 600 as part of the session on Applications of Computational Fluid Dynamics in Offshore Engineering.

The second technical paper is titled “Technology Qualification of Deepwater Transport Shuttle Adjustable Buoyancy System” which Collin will present on Wednesday, May 2 at 14:00 in room 600 as part of the session on Metocean Advances.

IoT: the Next Big Thing

Looking to the future, the Internet of Things and smart products are undoubtedly going to be the next revolution in the oil and gas industry and Trelleborg aim to be at the forefront of developments in this area.

Antony Croston, says: “The Internet of Things has the potential to transform the way people and businesses operate. As an industry, we acquire vast amounts of data, but we need to overcome the key challenges of empowering that data and transmitting it to truly unlock this potential. When we achieve this, we can use the information in real time and make effective decisions based on it. When we discuss the Internet of Things and machines talking to each other, being an intelligent system, I think that is quite a distance away for offshore oil and gas, however, it is undoubtedly where we are headed.”

OTC Houston 2017

Trelleborg will exhibit its range of innovative offshore solutions at OTC Houston 2018 in hall C on stand 3227. Products are designed with quality, performance and efficiency front of mind and include high performance buoyancy, insulation, passive fire protection, sealing solutions and hoses.
