Performance and application of Automotive Wiring Harness Protection Sleeve

The Automotive Wiring Harness Protection Sleeve is a kind of holey foamed and vulcanized at room temperature based on condensed hydroxyl-terminated raw silicone rubber, hydroxyl hydrogen-containing silicone oil as a foaming agent, and vinyl platinum complex as a catalyst. sponge-like elastomer.

In order to improve the quality of the foam, some other components, such as silicone oil, are added to make more gas during the vulcanization process; improve the feel of the foam and reduce the density. Adding diphenylsilanediol can not only control the structure of the foam, but also control the viscosity increase of the rubber during storage, but the amount should not be too much, otherwise it will affect the electrical properties of the foam. In order to improve the physical and mechanical properties of the foam, transparent silicone rubber can also be added. The amount of catalyst vinyl complex of chloroplatinic acid should not be too much, depending on the convenience of operation, otherwise the viscosity will increase and it is not conducive to operation; Good, soft and plastic, poor strength.
The Automotive Wiring Harness Protection Sleeve is liquid before vulcanization, suitable for potting material. The vulcanized foam can be used for a long time at -60~159°C. After 150°C, 72 hours of aging, or ten times of alternating cold and heat at 60~70°C, the foam still maintains its original performance.
Because of its high thermal stability, good heat insulation, insulation, moisture resistance, shock resistance, especially good shock resistance at high frequencies, the Automotive Wiring Harness Protection Sleeve is an ideal lightweight packaging material. Used in various electronic components, instruments, instruments, flying instrument wheels, etc, it can play the "three-proof" protection function of "moisture-proof, shock-proof, and anti-corrosion". In addition, it can also be used as a filling material for heat-insulating interlayers and floating in a salt spray atmosphere. Materials and sealing materials.In medicine, the protective cover of automobile wire harness can also be used as filling, repairing and imposing materials in orthopedic surgery.
