The advantages and disadvantages of automotive wiring harness materials

Harness the appearance of a layer of rubber or plastic and other substances for the package to protect the wiring harness also play an insulating role, then the insulating material is generally used in what kinds of materials, what are their characteristics

Natural rubber properties: with good elasticity and mechanical strength, excellent flex resistance, high tear strength and good cold resistance. Disadvantages: anti-aging is not good, not oil and ozone, flammable.

Neoprene characteristics: ozone resistance, heat aging, oil and other properties better, with flame retardancy and self-extinguishing; but low temperature resistance is not good.

Silicone rubber features: heat resistance, cold and weather is better; disadvantage is not oil.

EPDM features: weathering, ozone resistance, heat resistance, corrosion resistance, acid and alkali and other properties are better, and has high strength and high scalability; Disadvantages: poor adhesion, and flexibility is not natural Good rubber, poor oil resistance.

These insulation materials have their own characteristics, choose what kind of insulation material also determines the quality of the harness, so be sure to choose the right insulation material for processing or purchase.
