Description
Flurine®PC series is peroxide-cured fluoroelastomer, copolymerized with vinylidene fluoride (VF2), hexafluoropropylene (HFP), and bromine-containing or iodine-containing fluoroolefin monomers. Usually used in automotive, hydraulic applications, electrical and chemical industries. It has excellent processability and mechanical properties, excellent resistance to high-temperature steam. In addition, only a very short curing time is required. General | ||||
