Silicone rubber has excellent heat resistance, cold resistance, dielectric properties, ozone resistance and atmospheric aging resistance. The outstanding performance of silicon rubber is its wide use temperature, which can be at -90℃ (or lower temperature) to +300 Long-term use at ℃ (or higher temperature). However, the mechanical properties of the tensile strength and tearing strength of silicone rubber are poor, and its physical and mechanical properties are not as good as most synthetic rubbers at room temperature. In addition to nitrile silicone and fluorosilicone rubber, general silicone rubber has poor oil and solvent resistance. Good, so silicone rubber is not suitable for occasions under ordinary conditions, but it is very suitable for many specific occasions.
It is worth mentioning that in biomedical engineering, polymer materials play a very important role, while silicone rubber is a particularly important type of medical polymer materials. It has excellent physiological inertness, non-toxic, odorless, and non-toxic. Corrosion, anti-coagulation, good compatibility with the body, can withstand harsh disinfection conditions. According to needs, it can be processed into tubes, sheets, films and special-shaped components, which can be used as medical equipment, artificial organs, etc. Nowadays, there are specialized medical grade silicone rubber at home and abroad.
