The common materials and their advantages and disadvantages of wire harnesses are as follows:

PVC material:

Advantages: Low cost, good flexibility, sturdy, with fire-resistant/oil resistant properties, can be formulated into wire harnesses that are suitable for various environments and applications

Disadvantages: Low end PVC may contain harmful substances and may be unstable in special environments. Harmful gases and thick smoke may be produced during combustion

PE material (polyethylene):

Advantages: Environmental protection, usually tested by ROHS, excellent electrical insulation performance, good processing performance

Disadvantages: General weather resistance, not suitable for high temperature environments

PUR material (polyurethane):

Advantages: Excellent oil resistance, good toughness, wear resistance, cold resistance, water resistance, aging resistance, acid and alkali resistance, weather resistance, long service life, UV resistance

Disadvantages: High cost, higher price than PVC material

TPE/TPR material (thermoplastic elastomer/thermoplastic rubber):

Advantages: Good chemical and oil resistance, flexibility, and wear resistance compared to other materials

Disadvantages: Not resistant to high temperatures, usually cannot be used in environments above 80C for a long time

TPU material (thermoplastic polyurethane elastomer rubber):

Advantages: Wear resistant, oil resistant, transparent, good elasticity, high wear resistance, high tension, high tensile strength, toughness and aging resistance, environmentally friendly materials

Disadvantages: Not sturdy enough, prone to deformation

Silicone rubber:

Advantages: Good heat resistance, cold resistance, and weather resistance.

Disadvantage: Not resistant to oil

EPDM rubber:

Advantages: Good weather resistance, ozone resistance, heat resistance, corrosion resistance, acid and alkali resistance, high strength and high stretchability.

Disadvantages: Poor adhesion, lower elasticity than natural rubber, poor oil resistance

Natural rubber:

Advantages: Good elasticity and mechanical strength, excellent flexural flexibility, high tear strength, and good cold resistance.

Disadvantages: Poor aging resistance, not resistant to oil and ozone, flammable

Chlorinated rubber:

Advantages: Good ozone resistance, heat aging resistance, oil resistance, flame retardancy, and self extinguishing properties.

Disadvantage: Poor low temperature resistance
