About EPDM

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 healthcare and medical standards and approvals.


Perfluoroelastomer (FFKM)

Unrivalled chemical and thermal resistance

  • Reduce downtime and improve production efficiency
  • Sealing effectively under pressure or in a vacuum
  • Materials compliant to FDA 21 CFR.2400 (d), 3-A, USP Class VI, Cytotoxicity (USP 87)

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.

About FFKM

Isolast® is the Trelleborg Healthcare & Medical 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FFKM materials are terpolymers of monomers in which all hydrogen atoms have been replaced by fluorine.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.

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.
