As for aggressive rates, we believe that you will be searching far and wide for anything that can beat us. We can easily state with absolute certainty that for such good quality at such charges we are the lowest around for fluoroelastomer viton, perfluoroelastomer, Laminated Viton Sheet, We cordially welcome customers from at home and abroad to join us and cooperate with us to enjoy a better future.

Wholesale Fkm Material - Peroxide Curable FKM Raw Polymer – FUDI Detail:

Peroxide curing FKM is terpolymer of hexafluoropropylene, vinylidene fluoride and tetrafluoroethylene. It has below properties compare with traditional bisphenol curable fluoroelastomer.

* Excellent flow ability and mold release.

* High tensile strength and anti rearing performance.

* Rapid curing process.

* Excellent agent resistant performance.

* Good compressing set character.

How to choose fluoroelatomer?

FKM Copolymer vs FKM Terpolymer

Copolymer: 66% fluorine content, general application, resistance to oil, fuel, heat, chemicals. Common application is o rings, oil seals, packers, gaskets, etc.

Terpolymer: higher fluorine content than copolymer 68% fluorine content. Better resistance to oil, fuel, heat, chemicals, used in harsh environment which copolymer can’t satisfy the requirements.

Bisphenol curable FPM vs Peroxide curable FPM

Bisphenol curable FPM has low compression set, offer used for o-rings, shaft seals, piston seals. Price is good.

Peroxide curable FPM has better resistance to polar solvents, steam, acids, chemicals. Price is much higher. Its often used for wearable devices, extrusion fuel hoses.
