How many different insulation material for high temperature wire and cables?

1, polyperfluoroethylene propylene FEP

Poly (perfluoroethylene propylene) (FEP) is a copolymer of TFE and hexafluorpropylene (HFP), referred to as F46. Is a perfluorinated fluorine plastic, hardness and strength is higher than PTFE, but the use temperature is lower than PTFE 50°C.FEP has better weather resistance, radiation resistance, chemical stability is also good. Like PTFE and PFA, FEP offers excellent insulation. Combined with its flame retardant, low smoke and easy processing properties, FEP is an ideal material for local area Network (LAN) cable insulation. 205°C resistance, can be used as heating cable, thermocouple and automotive high temperature cable.

2, PTFE teflon

Ptfe referred to as F4, a representative perfluorinated plastic, commonly known as "plastic king". PTFE has excellent heat resistance (can be used at 260℃ for a long time), chemical medium resistance, flame retardant, low smoke and excellent electrical properties, is the ideal material for many high temperature cables.

3, polyvinylidene fluoride PVDF

Polyvinylidene fluoride (PVDF) is a commonly used fusing fluorine plastic, is a homopolymer of vinylidene fluoride, has excellent corrosion resistance, pollution resistance, weather resistance and ultraviolet radiation resistance, can be used to improve mechanical properties. Commonly used as paint and chemical pipe, chemical parts and container lining. However, PVDF two times larger than the tensile strength of ptfe, 6 times larger compression strength, abrasion resistance and nylon, weather resistance, radiation resistance, coloring, six power can withstand 10 Gy Y ray irradiation, not burning, smoke less, met with a high temperature has a high rate of carbide non-flammable, is also often used in the preparation of low frequency cable, Such as ceiling insulation cable, flame retardant cable, heating cable or optical fiber.

4, tetrafluoroethylene - ethylene copolymer ETFE
