Greene Tweed CHEMRAZ® SD517 Perfluoroelastomer
Categories:	Polymer; Thermoset; Fluoropolymer, TS; Thermoset Fluoroelastomer; Rubber or Thermoset Elastomer (TSE)
Material Notes:	Chemraz® SD517, a white-colored perfluoroelastomer, offers the broadest chemical resistance of any elastomer, combining the resilience and sealing force of an elastomer with chemical resitance and lwo extractables similar to PTFE. Providing the lowest temperature sealing properties of any perfluoroelastomer on the market (-22°F, -30°C), Chemraz SD517 is an ideal seal component for sub-ambient mechanical seal applications and is the preferred alternative to encapsulated O-rings. With its white color, Chemraz SD517 meets the needs of applications requiring non-black elastomers. Chemraz SD517’s many features make it well suited for critical applications and difficult seal replacement locations where maximizing MTBR (mean time between replacement) is paramount. Chemraz components are available for use as O-rings, gaskets, sanitary seals and many other custom shapes. This product is FDA and USP Class VI compliant making it an ideal product for electrometric applications requiring regulatory compliance. Applications:Mechanical seals Valves Pumps Mixers Fermenters Biomedical equipment Couplings Information provided by Greene Tweed.
