Products Description
FKM rubber
Fluoroelastomers are one of synthetic rubber.
And it was introduced in 1957 to meet the needs of the aerospace industry for a high performance seal elastomer.
And it was introduced in 1957 to meet the needs of the aerospace industry for a high performance seal elastomer.
Since then, the use of fluoroelastomer has expanded to many other industries, especially in the automotive, fluid power,
appliance, and chemical fields.
With over half a century of proven performance in oils, lubricants, fuels, oxygenate additives, and high temperatures.,
fluoroelastomer has developed a reputation for outstanding performance in high temperature and extremely corrosive environments.

FKM copolymer
Copolymers made from two monomers of VDF and HFP. And it is most often cured with bisphenol AF. It has good compression set characteristics.
It is widely used in many industry.
FKM terpolymer
Terpolymers are composed of VDF, HFP similar to FKM copolymer, but which also have a third monomer of tetrafluoroethylene (TFE).
TFE is added to increase the fluorine content of the polymer to give the polymer better chemical and heat resistance than acopolymer. However, compression set and low temperature sealing properties are not as good as copolymer. Terpolymers are also most
often cured with bisphenol AF.
Terpolymers are often used in automotive fuel systems and non-metallic expansion joints.

Peroxide FKM
Peroxide curable polymers are similar to terpolymers except a cure site monomer (CSM) is added to the polymer backbone.
Peroxide cross-linking provides fast cure rates and excellent physical properties and allows cross-linking of polymers

FKM copolymer
FKM copolymer is made from vinylidene fluoride and hexafluoropropylene with 66% fluorine content.
FKM terpolymer
FKM terpolymer is made from vinylidene fluoride, tetrafluoroethylene and hexafluoropropylene with 68% fluorine content.
FKM pre compound
FKM precompound is cure-incorporated fluoroelastomer rubber with 64%~70% fluorine content.
Mooney viscisty
Mooney Viscosity (ML (1+10’) at 121 °C: 15~180
