Seals Eastern Perflas® 9291 Highly Fluorinated Fluoroelastomer Seals
Categories:	Polymer; Thermoset; Fluoropolymer, TS; Thermoset Fluoroelastomer; Rubber or Thermoset Elastomer (TSE)
Material Notes:	Perflas 9291® seals are made of a chemical resistant highly fluorinated fluoroelastomer (FEPM - ASTM D1418 designated). Perflas9291 seals offer outstanding resistance to high temperatures (300°C/572°F). Perflas 9291 seals have been designed for very demanding sealing applications in aggressive chemical environments. Perflas 9291 seals resist attack by nearly all chemical reagents, including organic and inorganic acids, alkalines, ketones, esters, alcohols, fuels and hot water.
