In comparison, the comprehensive performance of EPDM is better, so the main material used for rubber parts for automotive electrical wiring harnesses is EPDM. In automotive applications, wire rubber part is used as a static seal and dynamic sealing element. Main features of automotive wiring rubber parts as following:
1) Wide temperature range, good resistance to high and low temperature;
2) It has high heat resistance, rubber parts in different areas and different temperatures. Can be used for a long time in an environment of 120 ° C, the maximum operating temperature is 150 ° C;
3) Direct contact with the atmosphere, exposure to the erosion of liquids such as rain, need to be able to withstand the cold outside the winter house, can be used in the sun, wet, cold natural environment for a long time without cracking;
4) Good elasticity, especially requiring good resilience; able to withstand multiple fatigue movements, capable of multiple deformation and recovery in various environments; can be used for both moving joints and stationary joints.
5) Precision finished product stability and strict finished product dimensional tolerance control.
