About PTFE:
UHMWPE (also known as Ultra High Molecular Weight Polyethylene) Sheet and Rod products are manufactured from the semi-crystalline polyethylene (PE) family. Chinese UHMWPE Sheet and rods' maximum molecular weight can reach to 5 million which has a positive impact on material performance in an abrasive environment.PTFE resistant to practically every chemical known to man and has a surface as slippery as ice on ice to which no substance will adhere. PTFE will operate continuously at 260°C in harsh conditions for long periods. It will not degrade when exposed to long term sunlight.
PTFE is available in sheets, rods, tubes and plates in various different grades. Other forms of PTFE available include: glass filled and Skived Tapes.
Advantages:
▪ Outstanding chemical resistance
▪ Superb electrical insulating properties and high dielectric properties
▪ Stability work in temperature range from 260°C down to liquid nitrogen temperatures (-260°C)
▪ And a very low coefficient of friction, resulting in unique non-stick behaviour
▪ Lowest co-efficient of friction
▪ Physiologically inert
▪ Non-toxic
Key Features:
▪ Unaffected by almost all chemicals
▪ Continuous use at high temperatures
▪ Slippery non-stick surface
▪ Outstanding dielectric properties
Applications:
▪ Seals
▪ Seats
▪ Packing
▪ Chevrons
▪ Piston rings, glide rings, lantern rings and back up rings
▪ Slide bearings
▪ Electrical and thermal insulators
PTFE Products:
▪
Molded Virgin PTFE:
Unfilled, natural
▪
15% or 25% Glass filled:
Oxidation and acid resistance, dimensional stability, good electrical properties
▪
25% Carbon filled:
Excellent dry wear resistance, good chemical resistance, lowest electrical resistance, good wear resistance in water applications
