CHENGDU CHENGUANG FLUORO-SLIICONE ELASTOMER CO., LTD

BDF631P is a medium to high viscosity curative incorporated fluoroelastomer copolymer.

This grade is well suited for application where good hot tear resistance and excellent mold release are required. BDF631P can be compounded to meet the major fluoroelastomer specifications.

BDF631P can be used for compression molding of oil seals or complicated geometries. It can be mixed using typical fluoroelastomer compounding ingredients. Mixing can be accomplished with two-roll mills or internal mixers. Finished goods can be produced by a variety of rubber processing methods. Basic characteristics of the polymer are as follows:
