PTFE tape

 PTFE tape untargeted intended for manufacturing the cushioning, sealing and insulating material.

 Fluoroplast tape produced by mechanical means of harvesting fluoroplastic-4, molded, followed by heat treatment of powder PTFE grades P-4 and VC (GOST 10007-80).

Tape counter to the effects of all media, with the exception of fluorine gas, chlorine trifluoride, molten alkali metals. Operating temperature range tape — from minus 269 ° C to plus 260 ° C.

 Film and tape from the F-4 are designed to isolate the wires and cables, for interlayer insulation in vehicles and parts.

 Film and tape from the F-4 can be used as insulation thermocouples in machines and appliances, engaged in welding of thermoplastic materials such as polyethylene, as a technological anti-adhesive insulation. The film and tape released the following grades (GOST 24222-80)
