Description: FKM premixed rubber is a kind of fluororubber premixed rubber added with a small amount of processing aids, fillers and all additive of curing systems. It solves the problem that the fluororubber vulcanizing agent is difficult to disperse during processing, and greatly improves the mixing efficiency of fluororubber.
Special properties:
Excellent wear & tear resistance; excellent ozone resistance & weather resistance
Heat resistance comparable to silicone rubber, better than any other rubber; excellent
resistance to superheated water or water vapor, excellent high vacuum resistance Good
appearance.
Excellent corrosion resistance, excellent resistance to moderate doses of radiation
Good low temperature performance
Good storage stability
Excellent antistatic property in low frequency and low voltage occasions
Calendering, extrusion fast, smooth surface, high strength, high hardness & low pressure
deformation, high chemical stability


Main applications:
FKM premixed adhesives are mainly used in high and low temperature sealing, vacuum equipment, chemical equipment, automobiles, aviation and other fields. It is also one of the indispensable high-performance materials for cutting-edge science and technology such as modern aviation, missiles, rockets, space navigation, ships, and atomic energy.
