Research and Development in the Americas
The Product Test Laboratory is part of Trelleborg Sealing Solutions Research and Development Center for the Americas, which also provides materials testing, materials development, product engineering and product development in support of Trelleborg’s continually evolving sealing product line. Trelleborg’s customers will greatly benefit from the additional capacity and further investment in R&D.

Colin Macqueen, Director of Technology for Trelleborg Sealing Solutions in the Americas, says: “We are very excited about this expansion as it affords us the opportunity to leverage new opportunities and support the continued growth of our sealing business. Well known for its decades of expertise and R&D innovations in sealing solutions, this investment further demonstrates Trelleborg’s commitment to quality, innovation and operational excellence over the long term.”

HA Traub Center
The HA Traub Center, also referred to as the HAT Center, was built in 1997 and named in honor of Hank Traub, co-founder of WS Shamban & Co., the developer of one of the sealing technologies used by Trelleborg Sealing Solutions. Mr. Traub was the holder of 17 seal-related patents, including many products still considered market leaders today. The HA Traub Center is one of eight R&D centers worldwide serving – among others – the automotive, aerospace, medical, pharmaceutical, food and semiconductor industries.

e-Learning on Engineered Molded Parts Now Available

A new e-Learning module gives introductory information on engineered molded parts, as well as more detailed lessons on product design and development, manufacturing and quality control.

Engineered Molded Parts

Building on the range of e-Learning modules from Trelleborg Sealing Solutions, the engineered molded parts lesson reaches beyond standard products and into the custom engineering that Trelleborg prides itself on.

The first part deals with definitions, applications and success factors, giving a rundown of the important factors needed to understand engineered molded parts. Moving from this, the second lesson provides a more detailed overview of the product design and development process which leads into the third lesson, concerned with manufacturing and quality at Trelleborg Sealing Solutions.

Glossary of Sealing Terms Featured in Flow Control

Flow Control magazine selected key terms from the Trelleborg Sealing Solutions glossary of commonly used sealing terms.

Trelleborg Sealing Glossary

Trelleborg Sealing Solutions aims to educate customers and other interested parties on sealing concepts with a continually growing range of resources to aid engineers who specify seals.

Flow Control magazine dipped into one of these, our glossary of commonly used sealing terms, and selected a listing from the thousands of terms online. Check out the terms they called out below, explore the complete online glossary or see the article

AXIAL SEAL: A term usually applied to an O-Ring where the seal is applied on the top and bottom surface. Also known as a face seal.

BACK PUMPING: The action in which fluid film passes between the seal and the mating dynamic surface during an extend stroke and then is returned to the system during the retract stroke through hydrodynamic principles.

BI-DIRECTIONAL SEAL: A seal used to prevent leakage across both sides of the seal under different levels of pressure or fluid exposure. Or a seal used in applications where motion (rotary – clockwise, counter-clockwise, linear– in or out, etc.) occurs in reversing fashion.

COMPRESSION SET: Permanent, unrecoverable deformation after a shape is compressed.

DIAPHRAGM: Dynamic elements with flexible walls in which to flex or roll that can be used in pumps, valves, regulators to regulate pressure, control the flow of media, or separate two media.

DYNAMIC SEAL: A seal used in hardware in which one of the hardware components is moving.

ELASTOMER: Any synthetic or natural material able to demonstrate a significant amount of elasticity. Sometimes used as a synonym for rubber.

EXCLUDER: A sealing device which keeps dirt, moisture, and other contaminants out of the sealing area to protect the seal, the fluid purity, electronic circuits, optical devices, or other components.

FLUOROCARBON: Organic compound having fluorine atoms in its chemical structure. This structure usually lends chemically and thermal stability in plastics.

GASKET: Static seal used between two parallel faces.

HYDRODYNAMIC SEAL: Seal with special patterns used to force fluid back under the sealing lip.

NITRILE: The most common of elastomers used in the production of O-Rings. Used because of resistance to hydraulic oils and good mechanical properties.

O-RING: A mechanical gasket or washer, an elastomer loop with a disc-shaped cross-section. Also known as packing or toric joint, it is seated in a groove at the interface between two or more parts and compressed, creating a seal.

PERMEATION: The penetration of a liquid or gas through a solid material; the degree of permeation is relative to a material’s permeability.

PTFE: Abbreviation for PolyTetraFluoroEthylene, a synthetic polymer containing fluorine, well known for its low friction, wide temperature range, and chemical inertness. It is most widely known under the DuPont brand name, Teflon.

RADIAL SEAL: Any seal designed to endure both radial and axial loads, such as those used in rotary elements, e.g., a shaft or rotating bore.

ROTARY SEAL: A seal in which the shaft, turns about its axis in relation to the fixed element in one direction only.

SEALING FORCE: The resultant force acting on the seal as a consequence of the individual forces acting on the seal joint.

STATIC SEAL: A seal in which there is no macro-scale dynamic motion between sealing surfaces.

TENSILE STRENGTH: Also known as Ultimate Tensile Strength (UTS), Breaking Load, or Breaking Stress, it is the amount of maximum stress used to rate a material’s capacity to withstand tensile stress, measured as the force per unit area—usually in pounds per square inch (PSI)—that a material can endure while being stretched at a constant rate before tearing. In rubber testing, it is the maximum PSI of the original cross-sectional area.

TOLERANCE: The permissible deviation from a specified value of a structural dimension.

VULCANIZATION: Process of chemical reaction in rubber materials in which chains are crosslinked, resulting in strength, elasticity, and other significant property changes.

Material releases by Daimler

In order to retain its position as a strong partner for tier-1 suppliers and OEMs, Trelleborg Sealing Solutions invests strategically in maintaining and improving its material and product portfolio.Material releases by Daimler

An example of this is the recent completion of a major milestone by the Trelleborg Sealing Solutions Sales Engineering team in Stuttgart, Germany. In cooperation with material specialists from Daimler, the entire portfolio of core elastomer materials was released by the Daimler’s material laboratory in Untertürkheim.

The portfolio of released materials consists of Trelleborg Sealing Solutions’ own Ethylene Acrylic (AEM), Ethylene Propylene Diene Rubber (EPDM), Fluoroelastomer (FKM), Hydrogenated Nitrile Butadiene Rubber (HNBR) and Silicone (VMQ) compounds, as well as, newly developed low temperature FKM materials. Specialized niche compounds such as abrasion resistant HNBR, low temperature NBR and high temperature AEM will be evaluated and released following joint-development programs.

In addition to the core portfolio of best-in-class elastomer and polytetrafluoroethylene (PTFE) based seals; Trelleborg Sealing Solutions also offers a unique two-component offering. Products such as Rubore® Seals, high-revolution rotary seals and complex plastic-to-LSR solutions, are ideally suited for new concepts coming through from the OEMs.
