PTFE
Virgin, or unfilled, PTFE is widely used due to it's unique combination of properties:
Characteristics:
Outstanding chemical resistance (unmatched by any other plastic)
lowest coefficient of friction of any plastic
superb electrical insulator
high resistance to weathering
wide working temperature range (-180C to +260C)
Typical applications:
Seats
Seals
Insulators
Sleeves and Liners
Bellows
bridge and pipe bearings
Properties (typical):
Colour: White
Density: 2.3 g/cm3
usage
1.In chemistry industry usa as sealing element,pipeline,pipe fitting and hight pure agentia household utensils ect
2.In machine industry use as piston ring,guide ring, machine tool guideways ect.
3.Electrical and Electronic Engineering use as electric wire,electric cable,electrical condenser film, insulation board ect.
4.In Construction Trades use as bridge,tunnel ahead ,large-scale chemical industry pipeline,storage tank supporting bearing slipper.
5.In light textile and other industry ,because ptfe product have nonstick properties ,it use in spinning,papermaking, foodstuff,rubber,ceramics and so on industry play a mucosa part of sticky or take off
