Cri-Tech FKX-719-75 FKM Fluoroelastomer, Durometer 75A
Categories: Polymer; Thermoset; Fluoropolymer, TS; Thermoset Fluoroelastomer; Rubber or Thermoset Elastomer (TSE)

Material Notes: The LS compounds are designed to give part shrinkage (out of the mold) and post-curing operation comparable to a nitrile or similar elastomers. In most cases, tooling changes are not required when switching over to an LS compound. NPC indicates no post-cure required to achieve high tensile and modulus values with good compression set and aging characteristics. FKHT is a high temperature resistant, low compression set compound. FKX is a high viscosity, high green strength, black fluorocarbon compound formulated for HAV and/or salt bath curing of O-ring cord and extruded profiles.
