Overview
Viton™ B-435C is a fully precompounded terpolymer composed of hexafluoropropylene (HFP), vinylidene fluoride (VF₂), and tetrafluoroethylene (TFE). Viton™ B-435C is a fluoropolymer with 68.5% fluorine content, allowing excellent heat and fluid resistance. This fluoroelastomer precompound has a nominal Mooney viscosity (ML 1+10 at 121 °C [250 °F]) of 40. Viton™ B-435C provides a large processing window with an excellent mold release and low mold fouling.
Viton™ B-435C is featured with a proprietary cure system that offers improved processing over other B typeB-type polymers. It offers a broad processing window, improved bonding to metal substrates, and enhanced resistance to mold fouling.

Features & Benefits
- Fully compounded with curative
- Fast cycle times and scorch-free molding
- Excellent adhesion to metal parts
- Improved processability and resistance to mold fouling
- Shorter production cycle and fewer rejects
- Calcium carbonate is not required in the final compounding, eliminating hygroscopy and dispersion issues associated with the CaCO3 addition
