From materials that perform in extreme temperatures or pressures, to compounds that resist challenging chemicals or meet stringent approvals, Trelleborg Sealing Solutions offers a range of elastomer materials to optimize the function of a wide variety of life sciences applications.
Ethylene Propylene Diene Monomer
Typical Healthcare & Medical Applications: Universal material used in a wide variety of applications, filling, dispensing, pumps, pipes and flange gaskets, valves, quick connectors, tanks, separators, homogenizers, decanters and heat exchangers.
Products Available: O-Rings, Kantseal, Flatseal, Gaskets, Diaphragms, bonded seals and custom components.
Ethylene Propylene Diene Rubber (EPDM) polymers are fully saturated, non-polar hydrocarbon based elastomers. Their polymer geometry gives them superior compatibility with polar fluids and polar solvents at elevated temperatures. The materials have high chemical resistance, giving long life in polar solvents, hot water and steam. In addition, they are suitable for contact with alkaline cleaning fluids.
All EPDM grades are peroxide cured and contain a very low amount of softeners and process aids. This reduces potential leach out to a minimum, lowering the risk of contamination. They have also been engineered to achieve enhanced chemical and thermal stability along with compliance to a variety of life sciences standards and approvals.
Typical Healthcare & Medical Applications: Universal material used in a wide variety of applications that require outstanding performance. Ideal for process systems requiring intensive CIP and SIP regimes or aggressive process media.
Products Available: Wide variety of standard and custom designs, O-Rings.
Isolast® is the Trelleborg Sealing Solutions range of high specification perfluoroelastomer (FFKM) compounds. We offer the widest portfolio on the market engineered to meet specific processing demands. Virtually inert, the materials perform well in a broad range of media including organic and inorganic oxides, acids, alkalis, amines, esters and steam at continuous operating temperatures from -25 °C to +325 °C / -13 °F to +617 °F.
Unrivalled Operating Characteristics
FFKM materials are terpolymers of monomers in which all hydrogen atoms have been replaced by fluorine. The absence of hydrogen in their molecular chain dramatically increases both their chemical and thermal resistance. The cross-linked molecular chains enable them to combine the resilience and sealing force of an elastomer with the chemical inertness and thermal stability of PTFE.
Typical Healthcare & Medical Applications: Mechanical seals, decanters, separators, pumps, tanks, valves, heat exchangers and equipment cleaned using clean-in-place and sterilize-in-place regimes.
Products Available: O-Rings, square seal, Kantseal, Flatseal™, gaskets, diaphragms, also reinforced. FKM can be bonded to other materials and delivered as engineered parts in almost any design.
Trelleborg Sealing Solutions has optimized the performance of our Fluoroelastomer (FKM) material range, engineering it to meet the specific criteria of the life sciences industry. Materials demonstrate good elevated temperature characteristics and compatibility to media used in cleaning regimes.
(NBR & HNBR)
Typical Healthcare & Medical Applications: Patient lifts, prosthetic knees and ankles, anti-vibration applications.
Products Available: O-Rings, gaskets, diaphragms
About NBR and HNBR
Acrylonitrile-Butadiene Rubber (NBR) is a good choice for applications where seals will not be exposed to harsh cleaning regimes, ozone or superheated steam. These materials are copolymers of butadiene and acrylonitrile. The percentage of these in the NBR and HNBR formulations determines their performance characteristics.
