Glossary of Common Search Terms used for Precix® Compounds & Products

Perfluoroelastomer – (Commonly searched for as per-fluoroelastomer, perfloroelastomer, perfluroelastomer, AMS7257, AMS 7257, AMS-7257.) Designed for very demanding sealing applications in aggressive chemical and high heat environments. Resistant to attack by nearly all chemical reagents including organic and inorganic acids, alkalines, ketones, esters, alcohols, fuels and hot waters. Used primarily by the chemical processing, aerospace and semiconductor industries. 

Perfluorocarbon – (Commonly searched for as FFKM, Kalrez® or Chemraz - AMS7257, AMS 7257, AMS-7257.) Very high temperature service applications, superior permeation resistance, extreme chemical resistance.
