1>PTFE Gasket
One of the most chemically-resistant materials available, PTFE and expanded ePTFE can fit the bill for extreme sealing with sheet gasketing, gasket tape, joint sealant, and universal gasket configurations. In addition to resisting most chemicals, the expanded PTFE gaskets are outstanding at resisting creep and cold flow. There are also gaskets created specifically for low bolt load, or for use in sealing fragile pipe flanges.
Sealing Devices offers a complete line of Gore PTFE gasketing materials and joint sealants.

Product Description:
PTFE parts
PolyTetraFluoroEthylene is a fluorocarbon-based polymer and is commonly abbreviated PTFE. 
it offers high chemical resistance,low and high temperature capability,resistance to weathering,
low friction, electrical and thermal insulation.
PTFE's mechanical properties are low compared to other plastics,but its mechanical properties can be enhanced 
by adding fillers such as glass fibers,carbon,graphite,molybdenum disulphide,and bronze.

Material Introduction:
PTFE molded sheet,gasket,rod bar,extrustion tubes is manufactured by molding method with PTFE granular resin. 
In fluoroplastics, PTFE got the most consumption and was used widely. 
It's an important material in variety of fluoroplastics. 
PTFE exhibits astonishing chemical resistance. 
This self-lubricating material provides a low friction coefficient, 
and is ideally suited for the manufacture of corrosion-resistant gaskets & seals. 

Feature Characteristics:
1.High and low temperature resistance(-180ºC~+260 ºC)
2.Corrosion resistance(strong acid, strong alkali and aqua regia etc)
3.Weather resistance Anti-aging
4.High insulation
5.High lubrication
6.Anti-flaming

Advantages:
1.Superior endurance in corrosion 
2.Non-flammable,limited oxygen index is under 90.
3.Low friction coefficient 
4.Non-viscous, Self-lubricating
5.Superior endurance in high & low temperature, can be used -180~260ºC
6.High electrical insulation
7.Atmospheric aging resistance
8.Low permeability, good gas barrier property
9.Good physiological compatibility and anti-thrombotic

Applications:
1.Corrosion resistance: widely used in all chemical containers and parts which contacted 
with corrosive media,such as tanks,reactors,equipment lining,valves,pumps,fittings,
filter materials,separation materials and pipe for corrosive fluids.
2.Abrasion resistance: can be used as a self lubricating bearing,piston rings,seal rings,
gaskets,valve seats,sliders,rails and lubricating materials in corrosive media etc.
3.Insulation materials: mainly used in the manufacture of various products with high temperature resistance,
high-frequency resistance, electrical insulation and arc resistance, such as high-frequency cables, 
moisture-resistant cables, capacitor coils, insulating cover for wire, etc..
4.Medical materials: such as artificial blood vessels,heart,esophagus,peritoneum,heart devices,Bearings,valves,
chemical piping,lining in the electrical,aerospace,machinery fields,a variety of intubation tubes and catheters.
5.Non-stick materials: can be used for non-stick coating such as non-stick pan and non-stick roller for food processor.
Support slider etc.
