Description

technical field

[0001] The invention relates to the technical field of cable materials, in particular to a chemical-resistant polyurethane elastomer and polyvinyl chloride composite cable material. Background technique

[0002] Polyvinyl chloride (PVC) is characterized by high withstand voltage and insulation resistance, and has properties such as flame retardancy, oil resistance, weather resistance, and chemical resistance, but its dielectric constant and dielectric loss are large, and its cold resistance is poor. Plastic has the characteristics of low price, large usage, and excellent performance in all aspects. It is mainly used in insulation, semi-conductive shielding and sheathing of various wires and cables for wires and cables below 1kV and local communication cables. Thermoplastic polyurethane elastomers have the characteristics of plastic reprocessing and rubber elasticity, and are excellent in cold resistance, abrasion resistance and antibacterial properties.
