Product Description

Fluoroelastomer (FKM)
Character:
Fluoroelastomer(FKM) is white/amber and semi-tranparent elastomer and it is odorless, nontoxic, non-flammable. Fluoroelastomer(FKM) owns excellent resistance to heat, oil and chemicals and it has outstanding physical-mechanical properties and resistance to weathering and can be dissolved in low M. W ketones and esters.

Application:
Our Fluoroelastomer (FKM) is equal to Dupont VITON A.
Fluoroelastomer (FKM) can be widely used in aviation, space, automobile, chemistry mainly for sealings, films, tubes which are heat-resistant and are suitable for both static and dynamic of hydraulic and lubricating systems.
Adding some curing agent, absorption acid agent and filling agent, Fluoroelastomers can be processed by molding and extrusion.
