PTFE SEMI-PRODUCTS
PTFE （polytetrafluoroethylene）is the best chemical resistance plastic. It has the lowest coefficient of friction of all known solid materials and a wide range of working temperature from-180 to +260°C.

APPLICATION:
★Resistance to chemical corrosion: Pipe hose, thin-wall beaker, reactor valve, diaphragm pump, lining of pipe-line equipment, filter etc.
★Resistance to aging, low friction coefficient: gland packing, pump seal, pull-rod sealing ring, mechanical seal, bearing, piston ring, guide ring, valve seat, valve clack, buffering ring etc.
★Good dielectric property: Wire and cable, insulating bushing of instrument, capacitor, radio insulation, transformer insulation etc.
★Self-cleaning property: Exterior wall coating, bridge slide block, machine guide track etc.
★Waterproof: Filter film, raincoat, sport suit, tabernacle etc.
