Is nitrile rubber better than silicone rubber in chemical resistance?

The material of zhidao is different for different media. It can be selected according to the actual media. Nitrile [jing] rubber is made from butadiene and acrylonitrile by emulsion polymerization. Nitrile rubber is mainly produced by low-temperature emulsion polymerization, which is extremely oil-resistant. Good, high abrasion resistance, good heat resistance and strong adhesion. The disadvantages are poor low temperature resistance, poor ozone resistance, poor electrical performance, and slightly lower elasticity.silicone nbr rubber handle grip

Silicone rubber has excellent heat resistance, cold resistance, dielectric properties, ozone resistance and atmospheric aging resistance. The outstanding performance of silicone rubber is the wide use temperature, which can be at -60 ℃ (or lower temperature) to + Long-term use at 250 ℃ (or higher temperature). However, the mechanical properties of silicone rubber such as tensile strength and tear strength are poor. At room temperature, its physical and mechanical properties are not as good as most synthetic rubbers. In addition to nitrile silicone and fluorosilicone rubber, the general silicone rubber is resistant to oil and solvents. Poor, so silicone rubber is not suitable for occasions under ordinary conditions, but the capacity is very suitable for many specific occasions.
