Problems solved by technology

Silicone rubber cable sheath has good flexibility, can withstand a certain pressure to protect the internal structure of the cable, and a small external force can produce a large deformation, and can return to its original shape after removing the external force, but in silicone rubber During the use of the cable sheath, due to friction with other objects, the rubber surface is damaged or even loses its original performance. In some special occasions, the high temperature resistance performance cannot meet the requirements, and the rubber is used for too long. The aging speed becomes faster, and the existing silicone rubber cable sheath materials are increasingly unable to meet the needs of use. Therefore, how to prepare a silicone rubber cable sheath material with good wear resistance, excellent thermal conductivity, and long aging resistance has become a current issue. technical issues to be resolved
