Publish Time: 2024-05-27
The long-term performance and stability of Harness silicone rubber sealing rings in automotive wiring harnesses are key factors to ensure the continued stable operation of automotive circuit systems. The following is a detailed analysis of the long-term performance and stability of harness silicone rubber sealing rings in automotive wiring harnesses:
Aging resistance:
Harness silicone rubber sealing rings have excellent aging resistance. For example, MF 9425 series silicone rubber can maintain a low pressure deformation level under the conditions of 125~150℃/1008h. Even after high temperature aging of 175℃/1008h, its pressure change can be maintained within 60%, showing its excellent heat resistance and aging resistance.
Heat resistance:
Harness silicone rubber sealing rings can maintain stable performance in high temperature environments. In automobile wiring harnesses, especially in high-temperature areas such as engine compartments, harness silicone rubber sealing rings can effectively prevent heat damage to wires and connectors, ensuring the normal operation of the circuit system.
Sealing performance:
Harness silicone rubber sealing rings have excellent sealing properties and can prevent moisture, dust and other impurities from entering the interior of the wiring harness, thereby protecting wires and connectors from corrosion and damage. This long-term sealing protection ensures the stability and reliability of the automotive circuit system.
Oil resistance:
In the automotive environment, harness silicone rubber sealing rings also need to have good oil resistance. Harness silicone rubber sealing rings can still maintain stable performance after aging test at 150℃/70 hours in IRM 901 and IRM 903 oil, showing their good oil resistance.
Durability:
Harness silicone rubber sealing rings are optimally designed and manufactured to have a long service life. Through rigorous trials and tests, harness silicone rubber sealing rings can work stably for a long time in automobile wiring harnesses, reducing the frequency of replacement and repair, and lowering maintenance costs.
Environmental adaptability:
Harness silicone rubber sealing rings can adapt to various complex automotive environments. Whether in high or low temperatures, humid or dry environments, harness silicone rubber sealing rings can maintain stable performance and provide reliable protection for automotive circuit systems.
In summary, harness silicone rubber sealing rings have excellent long-term performance and stability in automotive wiring harnesses. Its performance characteristics such as aging resistance, heat resistance, sealing, oil resistance and durability ensure the stability and reliability of automotive circuit systems. At the same time, the environmental adaptability of harness silicone rubber sealing rings also enables them to work stably in various complex automotive environments.
