EPDM sealing materials engineered for aseptic technology

Industry specific materials improve integrity

Ethylene Propylene Diene Rubber (EPDM) polymers are fully saturated, unpolar 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
  • Give long life in polar solvents, hot water and steam
  • Suitable for contact with alkaline cleaning fluids
  • Excellent in most dairy applications and with WFI (Water For Injection) at high temperatures.

Materials technology enhances capabilities

All recommended 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 FDA 21 CFR177.2600, 3-A, USP Class VI, Cytotoxicity (USP 87), NSF51 and several water approvals.

Areas of use:

  • Used in almost all types of applications as a universal material, suitable both in cleaning and sterilization processes.
  • Typical applications are filling, dispensing, pumps, pipe and flange gaskets, valves, quick connectors, tanks, separators, homogenizers, decanters and heat exchangers.

Products:

O-Ring, Square Seal, Kantseal, Flat Seal, Gaskets, Diaphragms, also reinforced. EPDM can also be bonded to other materials and delivered as engineered parts in almost any design.
