PTFE Backup Ring and Washer Used for Static Sealing
PTFE (King of plastic) is the most commonly known fluoroplastic with widest application. PTFE has properties such as corrosion resistance, aging resistance, high & low temperature resistance, good lubrication and insulation, non-sticky, non-toxic.
Features:
1.Outstanding chemical resistance
2.Superb electrical insulating properties
3.A wide working temperature range from 260°C down to liquid nitrogen temperatures (-196°C)
4. Low coefficient of friction, resulting in unique non-stick behavior
5.High dielectric properties
6.Non-toxic
Typical Applications:
1.Containers and pipework for reactive and corrosive chemicals
2.Electrical insulation parts
3.Sealing gasket, lining, valve seats, O-ring, slide bearing
