Silicone rubber is a kind of * * * high-performance material with * * * and low temperature resistance, good physiological stability, good resilience and deformation, ozone resistance, ultraviolet resistance, radiation resistance and other characteristics. Special silicone rubber has oil resistance, for example, fluorosilicone rubber has good oil resistance. Solvent-resistant property, it is suitable for aliphatic. Aromatic and chlorinated hydrocarbon solvents. Various petroleum-based fuel oils. Hydraulic oil and some synthetic oils, such as ester lubricating oil. The stability of silicone ester fluid hydraulic oil is good at room temperature, and the phenylene silicone rubber has good radiation performance.
[In terms of electrical performance] When exposed to moisture, water or temperature rise, the change is small, even if the silicon dioxide generated by short circuit combustion is still an insulator, which means that * * * electrical equipment continues to work, so it is suitable to make wires, cables and lead wires.
[Surface performance] Comb water, which is not sticky to many materials, can play an isolation role.
Due to the good stability of silicone rubber, it can meet the needs of supporting equipment in various aspects of civil industry.
