Specifically developed for food and beverage applications, both sealing materials are FDA (Food and Drug Administration), USP (United States Pharmacopeia) Class VI and 3-A Sanitary Standards approved. Ideal for filling and packaging equipment, these Isolast compounds provide outstanding resistance to concentrated flavoring additives, which can cause excess swelling in conventional elastomers. In addition, they withstand frequent harsh CIP (Cleaning In Place) and SIP (Sterilization In Place) regimes, ensuring extended seal life.
Martin Krüger, European Sales Manager for food and beverage sealing applications at Trelleborg Sealing Solutions, says: “We supply many standard seals and customer-specific molded parts made from Isolast, such as flange seals for sockets, safety valves or seals for retractable spray nozzles. Thanks to Isolast compounds specifically developed for food and beverage applications, we can provide individual, cost-effective components offering industry-specific performance for demanding filling applications.”
Isolast is suitable for seals and molded parts that are exposed to extreme chemical and thermal conditions. Being almost chemically inert, Isolast is resistant and durable in contact with media including solvents, acids, alkalis or steam and has operating temperatures between -40 °C and +325 °C. This makes Isolast especially suitable for use in foodstuff technology, such as in beverage and milk industry filling systems, where seals in contact with foodstuffs must remain neutral while withstanding cleaning processes that involve hot steam or aggressive media.
