First, excellent electrical insulation properties, the electrical insulation properties of the rubber roller are less changed when the moisture, frequency or temperature rises. The cerium oxide formed after combustion is still an insulator, so in the environment where insulation is required, the rubber roller The frequency of use is also high. In addition, the rubber roller has a small number of carbon atoms in the molecular structure and does not use carbon black as a filler, so that scorch is less likely to occur during arc discharge, and thus it is very reliable for use in high pressure applications. Its corona resistance and arc resistance are extremely good, the corona life is 1000 times that of polytetrachloroethylene, and the arc life is 20 times that of fluororubber.

Second, excellent high temperature resistance, working temperature range -100 to 350 degrees. Excellent resistance to ozone aging, oxygen aging, photoaging and weathering. The performance of the silicone roller in the free state for several years has not changed, so the use of the silicone roller in many industries is also convenient.

Third, the silicone roller has special surface properties and physiological inertness, and the surface energy of the silicone roller is lower than that of most organic materials. Therefore, it has low hygroscopicity and is immersed in water for a long time. Its water absorption is only 1%, the physical and mechanical properties are reduced, and the mildew resistance is good. Therefore, silicone rubber is also used in underwater operations or in a humid environment. In addition, the silicone roller does not stick to many materials and can act as an insulator.
