What is the insulating layer of the wire for electronic connection?

- Mar 20, 2019-

The insulation layer of the electronic connection wire is mainly PVC, namely polyvinyl chloride.

1. Basic features:

PVC is one of the world's largest production of plastic products, widely used.Polyvinyl chloride resin is white or light yellow powder.Different additives can be added according to different USES, polyvinyl chloride plastics can present different physical and mechanical functions.A variety of hard, soft and transparent products can be made by adding plasticizer in polyvinyl chloride resin.The density of pure polyvinyl chloride is 1.4g/cm3, and the density of polyvinyl chloride plastic parts with plasticizers and fillers is generally 1.15-2.00g/cm3.

The electronic wire cover of our product model UL1571 is relatively hard. Generally, hard polyvinyl chloride is used as structural material with rare and good tensile, bending, compression and impact resistance.

The softness, elongation at break and cold resistance of soft polyvinyl chloride increase, but the brittleness, hardness, tensile strength decrease.Polyvinyl chloride rare electrical insulation function, can be used as low-frequency insulation materials, its chemical stability or.Due to the poor thermal stability of polyvinyl chloride, long time heating will lead to decomposition, release HCL gas, make polyvinyl chloride discoloration, so its application range is narrow, the use temperature is generally between -15~55℃.

2.Main applications:

Because of the high chemical stability, it can be used to produce anti-corrosion pipes, pipe fittings, pipelines, centrifugal pumps and blowers, etc.Polyvinyl chloride hardboard is widely used in chemical industry to make the lining of various storage tanks, corrugated boards of buildings, doors and Windows structures, wall decorations and other building materials.Because the electrical insulation function is good, can be used in the electrical and electronic industry, for the manufacture of plugs, sockets, switches and cables.In everyday life, polyvinyl chloride is used to make sandals, raincoats, toys and artificial leather.
