Features
1. Excellent high and low temperature resistance, with a working temperature range of -100 to 350 degrees. Outstanding resistance to ozone aging, oxygen aging, light aging, and weather aging. Silicone rollers maintain their performance unchanged when placed outdoors in a free state for several years, which is one of the reasons why many industries use silicone rollers.
2. Excellent electrical insulation performance, the electrical insulation performance of silicone rollers changes little when damp, frequency varies, or temperature rises. After burning, it generates silica, which remains an insulator, so silicone rollers are frequently used in environments that require insulation. In addition, silicone rollers have fewer carbon atoms in their molecular structure and do not use carbon black as a filler, making them less prone to scorching during arc discharge, thus making them very reliable for high-voltage applications. Their resistance to corona discharge and arc discharge is extremely good, with a corona resistance life 1000 times that of polytetrafluoroethylene and an arc resistance life 20 times that of fluororubber.
3. Silicone rollers have special surface properties and physiological inertness, with a surface energy lower than that of most organic materials. Therefore, they have low moisture absorption, absorbing only 1% of water when soaked for a long time, with minimal decline in physical and mechanical properties, and good anti-mold performance, making silicone suitable for underwater operations or humid environments. In addition, silicone rollers do not stick to many materials, serving as a separating agent.
4. Silicone rubber is odorless and non-toxic, with no adverse effects on the human body, and the body's reaction is mild, exhibiting excellent physiological inertness and aging resistance.
5. High breathability, silicone rollers have extremely superior breathability compared to other polymer materials, with a permeability to air at room temperature 30-40 times that of natural rubber. In addition, silicone rollers also exhibit selectivity for gases, with different permeability for different gases.
