Viton™ A-401C, formerly VTR-6600, is a precompounded fluoropolymer that provides superior resistance to compression set and improved rheology at high shear rates.
Viton™ A-401C fluoroelastomer (FKM) is a fully precompounded A-family dipolymer composed of hexafluoropropylene (HFP) and vinylidene fluoride (VF₂).
Viton™ A-401C contains 66% fluorine content and offers excellent processing and rheology characteristics. Viton™ A-401C is designed to meet the fluoroelastomer specifications of Mil-R-83248B, AMS 7276D, and AMS 7259A
