    What is the insulating layer of the electronic connection wire?

    The insulating layer of the electronic connection wire is mainly PVC, that is, polyvinyl chloride.
    Its basic features:
    PVC is one of the world's largest production of plastic products, cheap, widely used, polyvinyl chloride resin is white or light yellow powder. Depending on the application, different additives may be added, and the polyvinyl chloride plastic may exhibit different physical and mechanical properties. In the polyvinyl chloride resin by adding the right amount of plasticizer, can be made of a variety of hard, soft and transparent products.
    Pure polyvinyl chloride density of 1.4g / cm3, adding plasticizers and fillers such as the density of PVC plastic parts is generally 1.15-2.00g / cm3. Our UL1571 electronic wire sheath is relatively hard, generally with hard polyvinyl chloride has a better tensile, bending, compression and impact resistance, can be used alone as a structural material.
    Soft polyvinyl chloride softness, elongation at break, cold resistance will increase, but the brittleness, hardness, tensile strength will be reduced. Polyvinyl chloride has a better electrical insulation function, can be used for low-frequency insulation materials, the chemical is not chaotic Ye Hao. Because the heat of PVC is not bad, long heating will lead to decomposition, release HCL gas, so that PVC discoloration, so its narrow range of applications, the use of temperature is generally between -15 ~ 55 degrees.
    The main purpose:
    Because the chemical is not chaotic, it can be used for the production of anti-corrosion pipes, pipe fittings, tubing, centrifugal pumps and blowers. Polyvinyl chloride hard board is widely used in the chemical industry to produce a variety of storage tank lining, building corrugated board, doors and windows structure, wall ornaments and other building materials. Because the electrical insulation function is excellent, in the electrical, electronics industry, for the manufacture of plugs, sockets, switches and cables. In the daily life, PVC used in the manufacture of sandals, raincoats, toys and artificial leather!
