Why does the Automotive Wiring Harness Protection Sleeve have insufficient toughness?

The Automotive Wiring Harness Protection Sleeve is mainly used in various fields due to its toughness and softness. The Automotive Wiring Harness Protection Sleeve is soft, resistant to tension and does not deform, and is widely used in life. However, once the Automotive Wiring Harness Protection Sleeve loses its original performance, it will become meaningless. Some common Automotive Wiring Harness Protection Sleeve will lose their original performance after long-term use, such as product deformation and insufficient toughness. What is the reason for this? Why does the Automotive Wiring Harness Protection Sleeve have insufficient toughness?

The various additives added to the raw materials of the Automotive Wiring Harness Protection Sleeve during production will lead to different performances of the product. Among them, "silica" is the main reason for the lack of toughness of the product. White gray black is one of the main components of the raw material of the Cable Sleeve. The silica used in the production of different hardness materials is also different, and the addition of an appropriate proportion can also make the surface activity of the raw material. Secondly, in addition to the reason of raw material additives, the molding vulcanization of the product also has a certain influence. The elasticity of the product is directly related to the hardness of the raw material.
During molding and vulcanization, adding too much vulcanizing agent will lead to too active fluidity, and the produced product is either too soft or the tensile force is too high, while adding too little vulcanizing agent will cause the product to be vulcanized and unable to be molded. Therefore, the addition of vulcanizing agent and the control of temperature and time during the molding vulcanization process will be very important.
