white pure PTFE valve Gasket

1.Feature:

> Acid and alkali resistant
> Chemical resistant
> has minimum friction coefficient of all know pure material
> Non-viscous, no aging
> Now molds can be made according to customers requirements.

Glass Fiber:	Increases compressive strength, rigidity and wear. Reduces creep and cold flow Minimal effect on chemical and electrical properties
Carbon:	Increases compressive strength, hardness, wear, and load properties. Good chemical resistance Various types and amounts of carbon can be added to alter conductivity
Graphite:	Reduces coefficient of friction Reduces initial wear Increases strength
Molybdenum Disulfide:	Increases hardness, stiffness, and wear Minimal effect on chemical and electrical properties
Bronze:	Increases hardness and wear resistance Increases dimensional stability and compressive strength Not suitable for corrosive or electrical applications

2.Applications:
As filled product has good corrosion-resistance,low friction and good hardness,it is widely used for the production of gasket,valve,bearing,slide,pistion ring,insulating sleeve,and self-lubricating seal.
