Purpose in electron and electrical industry:
Telstar, coaxial septa of the television power transmission, ultra-high frequency communication, miniature electrical machinery winding, control cable of the firepower power  plant and electric wire insulating layer double-water inner-cold drawing water pipe for computer use, electrobath of the thermal power plant.

The teflon capacitor, coaxial linker, wave-guide canal liner, attachment, insulating tape, tube socket, switches (gas welding), bobbin, printed circuitry board, solid distance and through line columniation, jet engine insulated wire and other insulation component, cable sheath heat-resisting electric wire.

Purpose in mechanical industry:
Making use of the low friction coefficient and none- viscidity of the teflon, Simultaneously, in order to improve the ability of abrasion proof and the anti- squirm, generally using filling teflon, airproof (compression and airproof, supporting link, guide link, rising curl, glide airproof, mechanical airproof, oil airproof), axletree (molding axletree, join axletree, teflon soak agglutination metal axletree), piston ring(cutting ring, none-cutting ring, attrition ring, piston sign airproof and fill airproof), roll, air-enter connector and so on in machine parts’s manufacture .
