100% Virgin Expand PTFE Spiral Wound Envelope Gasket

100% Virgin PTFE Skived Sheet / Molded Sheet / Teflon Tape / F4 Tube / Pipe / Plastic Rod / Packing etc.
 
PTFE Skived Sheet is manufactured by technique of compacting, sintering, rotary cutting with PTFE granular resin. It has good dielectric performance and non-aging, best anti chemistry corrosion ability and wide applying intension range.
PTFE Molded Sheet is manufactured by molding process with PTFE regular resin and sintering. It is very suitable for seals,lining,diaphragm,spacer guide and bearing pad for bridge.

Main Features:
1.Heat resistance property---It is able to wok stably between -180°C to +260°C.
2.Excellent non-sticky property---It easier to remove those resin, dopes, oil and other sticky things.
3.Good mechanical property with no distortion and low friction coefficient.
4.Excellent insulation property.
5.Materials like carbon, graphite and glass fiber can be filled.
6.Virgin and recycled materials are available.
 
PTFE Additives and Benefits:
Filled PTFE ring has strong corrosion resistance and friction-resistance,By adding filler such as glass fiber,carbon fiber,copper powder,graphite,asbestos,MOS2,AL2O3,carbon powder,ceramic fiber,metal powder,polyamide,PS,the hardness,compression strength and abrasion resistance of the products is improved ,in addition,it will have good heat conductivity and low heat expansion coefficient.
 

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
