PolyFlex™ Gaskets

PolyFlex provides a composition that provides memory, flexibility and the superior chemical resistance of PTFE contact surface. If you are looking to extend chemical resistance PolyFlex provides the maximum PTFE coverage of the elastomer substrate. Providing greater life where chemicals are most aggressive. Materials include PTFE with EPDM, Viton GF-600’s or Platinum Silicone. SteelFlex® is rubber bonded to PolySteel, our stainless steel filled PTFE material. While stainless steel filled PTFE materials provide great steam resistance, that composition has lost market share to products that are more compressible and can hold a seal in vacuum application. SteelFlex® is the only Stainless Filled PTFE product that addresses those issues. Materials include PolySteel with EPDM, Viton GF-600’s or Platinum Silicone.
