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


Latest company news about 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

After PTFE(F4) and FEP(F46), ETFE is the third largest variety of fluorine plastic development, referred to as F40. It is a fluorine plastic with similar excellent performance of polytetrafluoroethylene, and has good sound permeability and weather resistance, permeability resistance, non-toxic, solvent resistance and radiation resistance. It is a strong fluoroplastic with abrasion resistance and wear resistance. ETFE can also withstand high temperatures up to 150 ° C, and cross-linked ETFE can withstand high temperatures up to 200 ° C. It is also one of the fluorine plastics that are difficult to process. ETFE IS mainly used for wires and cables that are flame retardant, low smoke, resistant to chemical media, and resistant to abrasion and wear. Can be used to prepare various specifications of wire and cable, such as automotive, aviation cable and heating electricity
5, fluorine elastomer
Fluorine elastomer also known as fluorine rubber, it is a kind of fluorine containing synthetic rubber, is heat resistant and oil resistant synthetic rubber, has been used in harsh use environment. The main types of fluorine rubber are VDF-HFP system, TFE-Pr system, VDF-HFP-TFE system, VDF-TFE-PMVE system, fluorine silicone rubber, TFE-PMVE system, etc.
Among them, binary copolymer fluorine rubber is widely used because of its excellent heat resistance, oil resistance, drug resistance and small compression deformation. Especially VDF-HFP fluorine rubber in the characteristics, processing, price and other aspects of balance and widely used. At present, the application of this kind of fluorine elastomer in wire and cable is still relatively small, mainly used in the military field and aerospace, aviation and automobile industry.
The above is several insulation materials commonly used in high temperature cable, which have their own characteristics. Users should choose high temperature cable according to the actual situation when buying cable. If you  have any questions about this, you can click on the website customer service for consultation!
