Greene Tweed CHEMRAZ® SD625 Perfluoroelastomer
Categories: Polymer; Thermoset; Fluoropolymer, TS; Thermoset Fluoroelastomer; Rubber or Thermoset Elastomer (TSE)

Material Notes: Chemraz® SD625, a black-colored perfluoroelastomer, offers the broadest chemical resistance of any elastomer, combining the resilience and sealing force of an elastomer with chemical resistance and low extractables similar to PTFE. Not only is it FDA and USP Class VI compliant, but Chemraz SD625 also passes USP Physicochemical Testing, USP <661>, and has been tested to USP elastomeric closures, USP <381>, making it the most comprehensively tested perfluoroelastomer on the market. Critical applications and difficult seal replacement locations where maximizing MTBR (mean time between replacement) is paramount will benefit greatly from Chemraz SD 625.

With is outstanding performance in high temperatures, Chemraz SD625 delivers excellent performance in hot water and steam and in CIP/SIP processes. Chemraz SD625 is also well suited for dynamic applications

Chemraz components are available for use as O-rings, gaskets, sanitary seals and many other custom shapes.

Applications:

  • Mechanical seals
  • Valves
  • Pumps
  • Mixers
  • Fermenters
  • Biomedical equipment
  • Couplings
