3.Good mechanical property with no distortion and low friction coefficient.
4.has minimum friction coefficient of all know pure material
5. Non-viscous, no aging
6.Now molds can be made according to customers requirements

Description

?

Enhanced PTFE product have strong corrosion-resistance and friction-resistance.By adding filler such as glass fiber,carbon fiber,graphite,MOS2.Al203,Carbon fiber powder, compression strength and abrasion-resistance of the product is improved.In addition, it will have good heat conductivity and low heat expansion coefficient.High frequency coaxial coupling,Connector and attenuator in electronics and telecommunication,Also it is applicable to various sealing gasket,sealing plug or sealing seat in valves,air conditioner,refrigerator and automotive parts as well as other apparatus with high precision requirement.
