Product Description:
Excellent high and low temperature resistance
Operating temperature range - 100 to 350 ℃. Excellent ozone aging resistance, oxygen aging resistance, light aging resistance and weather aging resistance. The performance of the silicon rubber roller has not changed for several years when it is placed outdoors in a free state, so the use of silicon rubber roller in many industries is also one of its conveniences.
Excellent electrical insulation
The electrical insulation performance of the silicon rubber roller changes little when it is affected with moisture, frequency change or temperature rise. The silicon dioxide generated after combustion is still an insulator. Therefore, the silicon rubber roller is used more frequently in some environments where insulation is required. In addition, there are few carbon atoms in the molecular structure of silicone cots, and carbon black is not used as filler, so it is not easy to scorch during arc discharge, so it is very reliable in high-voltage applications. Its corona resistance and arc resistance are extremely good. Its corona resistance life is 1000 times that of polytetrachloroethylene and arc resistance life is 20 times that of fluororubber.
Special surface properties and physiological inertia
Silicone cots have special surface properties and physiological inertia, and their surface energy is lower than that of most organic materials. Therefore, it has low moisture absorption. After long-term immersion in water, its water absorption is only 1%, its physical and mechanical properties do not decline, and its mold resistance is good. Therefore, silica gel is also used for underwater operations or wet environments. In addition, the silicon rubber roller does not adhere to many materials and can play an isolation role.
Excellent physiological inertia and physiological aging
Silicone rubber is tasteless and non-toxic, has no adverse effects on human body, has slight body reaction, and has excellent physiological inertia and physiological aging.
High permeability
Compared with other polymer materials, silicone rubber roller has extremely superior air permeability. The air permeability at room temperature is 30-40 times higher than that of natural rubber. In addition, silicone rubber roller also has gas selectivity, and its permeability to different gases is different.
