Description
Description
Flurine® L series is a low-middle Mooney bisphenol-vulcanized fluoroelastomer with a fluorine content of 66%.
It is a copolymer of vinylidene fluoride (VF2), hexafluoropropylene (HFP) and perfluoroalkyl vinyl ether (PMVE).
It is commonly used in automotive, hydraulic, electrical and chemical industries. It has excellent heat and chemical resistance.The outstanding performance is low-temperature elasticity, which are particularly suitable for O-ring seals for fuel injectors.
