Main plastic raw materials of wires and cables

As a wire and cable factory, we have to make sure the plastic material for the cable, Yihetai cable introduces you the details as below.
Wire and cable use its material properties and functions, divisible materials, conductive materials, filling materials, etc. , plastic, XLPE, PU), rubber, some of which are certain things, mainly the structure and material of PE, such as polyvinyl chloride, general and other components, as long as the composition is changed, it can be used on insulation or sheathing.
The production line needs plastic raw materials, PE plastic particles, XLPE (Liansu plastic)
PVC is generally used as insulation and sheathing material.
(1) PVC granules: PVC plastic polyether additives and light-proof resin are added with various granular antioxidant brighteners, plastic luminescent agents, and are made by mixing them. They are materials for accessories of cables. One of them has the properties of electrical conductivity, chemical corrosion resistance, corrosion resistance, good insulation performance and easy processing.
(2) PE plastic particles (PE):
General physical properties of PE: white waxy, translucent, flexible and tough, slightly stretchable, lighter than water, non-toxic; combustion characteristics: flammable, continue to burn after leaving the fire, the upper end of the flame is yellow and the lower end is blue , it melts and drips when burning, and emits the smell of burning paraffin.
1. MDPE: Medium-density polyethylene, also known as medium-pressure polyethylene and Philips polyethylene, has similar properties to high-density polyethylene.
2. HDPE: High-density polyethylene, also known as high-pressure polyethylene, has excellent comprehensive properties, such as improved heat resistance and mechanical strength, improved barrier properties to water vapor and gas, and superior environmental stress crack resistance. .
3. LDPE: Low-density polyethylene is the lightest one in the polyethylene series, also known as low-pressure polyethylene. Its structural characteristics are nonlinear, with low crystallinity and softening point, and good flexibility and elongation. , electrical insulation, transparency, and high impact strength. Poor environmental stress cracking resistance.
(3) XLPE (cross-linked polyethylene) plastic particles, XLPE plastic particles mainly have the following two types:
A silane cross-linking agent is called silane cross-linking material, which is mainly used to make the insulating layer of low-voltage wires and cables;
One uses dicumyl peroxide as a cross-linking agent, which is mainly used to make the insulating layer of medium and high voltage cables.
