PVC coated nylon wire is a composite cable made from nylon with a polyvinyl chloride coating. Combining the high strength and abrasion resistance of nylon with the chemical resistance and easy processing of PVC, it is widely used in construction, industry, transportation, electronics, and other fields. The following is a detailed analysis of its core characteristics:

1. Abrasion Resistance and Tensile Strength

The nylon base imparts high strength and abrasion resistance to the cable, while the PVC coating further enhances its surface hardness and reduces frictional loss. For example, in building wiring, PVC coated nylon wire can withstand frequent conduit routing without damaging the insulation.

2. Chemical Resistance

The PVC coating offers excellent resistance to chemicals such as acids, alkalis, and oils, making it suitable for industrial environments or outdoor applications. For example, in machine tool control circuits, where the cable is exposed to lubricants for extended periods, the PVC coating effectively prevents the insulation from swelling or hardening.

3. Temperature Resistance and Flame Retardancy

Nylon has a high melting point of 215°C, while the PVC coating resists dripping at high temperatures. This combination of properties gives the cable short-term high-temperature resistance. The PVC coating also meets the UL1581 VW-1 flame retardant standard, releasing low smoke during combustion and offering superior safety compared to traditional PVC cables.

4. UV and Aging Resistance

The PVC coating shields UV rays, slowing the aging of the nylon base material and extending its outdoor service life. For example, in highway surveillance equipment wiring, where cables are exposed to sunlight for extended periods, PVC coated nylon wire can maintain stability for over 20 years.

5. Flexibility and Conduit Ease

Despite the relatively high hardness of the nylon base material, the PVC coating, through an optimized formulation, enhances cable flexibility and reduces conduit friction. For example, cables with a diameter of 0.5-6mm can achieve a delivery speed of up to 500 m/min, making them suitable for large-scale wiring projects.
