Cable Insulation Material

Cable Insulation Material

Cable Insulation Material is a pellet insulating material primarily composed of polymer compounds, manufactured through processes such as compounding and pelletizing. It is mainly used for producing the insulation layer of wires and cables. Its key characteristics include:
Pellet form: Facilitates extrusion, injection molding, and other processing techniques.
Electrical insulation: High volume resistivity and excellent dielectric strength.
Customizability: Adjustable formulations to achieve properties such as high-temperature resistance, flame retardancy, and halogen-free composition.

Cable Insulation Material List

Type	Typical	Characteristic
PVC	PVC insulation material	Low cost, easy to process, but containing halogens and burning toxic smoke
