Raw materials for wires and cables

Raw materials used in wires and cables are natural rubber, SBR, EPDM rubber, neoprene rubber, chlorosulfonated polyethylene, silicone rubber, fluorine rubber, butyl rubber, butyl rubber, nitrile rubber, Polybutadiene Rubber, oxygen, etc. And the insulated and sheathed additives are curing agent, accelerator and activator, softening agent, antioxidant, reinforcing agents, fillers, etc.



The manufacturing of wire and cable has a wide range of technology categories. For example, from the smelting and pressing of nonferrous metals to plastics, rubber, paints and other chemical technology; from fiber wrap, knitting and other textile technology to wrapped metal and metal strips longitudinally wrap and welding of metal forming process, etc.

Various materials used in manufacturing wire and cable with large a number of types, varieties, specifications. Therefore, the use of various materials, spare capacity, batch cycle and quantities required for final approval.

Rubber and wire is commonly used in producing cables. Organic polymer materials high temperature cables are mainly fluorine plastic and silicone rubber, cables are poly-fluorinated ethylene propylene (FEP, commonly known as F46), polytetrafluoroethylene (PTFE), ethylene-tetrafluoroethylene copolymer (ETFE, commonly known as the F40), polyvinylidene fluoride (PVDF). Also methyl vinyl silicone rubber, the operating temperature range is -60℃～180℃.

Here I'd like to introduce some of the materials from OKCHEM that can manufacture wires and cables.

1 Silicone rubber is soft, resistant to ozone, corona, flame, good insulation properties, resistance to high and low temperature （-60 - 120℃）, good corona resistance and arc resistance. They are safe and reliable materials in the production of wires and cables. Silicone rubber is a gelatinous material for wire and cable. Methyl vinyl silicone rubber is base glue, adding the necessary additiveSs such as reinforcing agents, structure control agents, heat-resistant agent, compatibilizers, then made by mixing, thin-pass, filtered, vulcanized and other production processing. This product is fast curing and has good mechanical and excellent extrusion properties. It can atmospheric pressure hot air curing and continuous steam curing. It suitable for extrusion wire and cable insulating layer, hoses, plastic ropes, profiled rubber strips. Also add various pigments according to needs.

2 PTFE before normal use temperature of 260℃, PTFE has excellent thermal stability. But it will thermal degradation at a higher temperature. Thermal degradation rate is related to temperature, time, pressure, environment and other factors. I will add more next time. If you have interest, read more here thanks!
