Extended data
Main properties of silicone rubber
(1) High temperature performance. The remarkable feature of silicone rubber is its high temperature stability. Although the strength of silicone rubber at room temperature is only half that of natural rubber or some synthetic rubber, it can still maintain certain flexibility, resilience and surface hardness at high temperature above 200℃, and its mechanical properties have not changed obviously.
(2) The glass transition temperature of silicone rubber with low temperature performance is generally -70~-50℃, and the special formula can reach-100℃, which shows its excellent low temperature performance. This is of great significance to the aerospace industry.
(3) The Si-O-Si bond in weather-resistant silicone rubber is very stable to oxygen, ozone and ultraviolet rays, and has excellent weather resistance without adding any additives.
(4) Electrical performance. Silicone rubber has excellent insulation, corona resistance and arc resistance.
(5) Physical and mechanical properties. The physical and mechanical properties of silicone rubber are worse than ordinary rubber at room temperature, but better than ordinary rubber at 150℃ high temperature and -50℃ low temperature.
(6) Oil resistance and chemical reagent resistance. Ordinary silicone rubber has moderate oil resistance and solvent resistance.
(7) air permeability. The permeability of silicone rubber to air, nitrogen, oxygen, carbon dioxide and other gases at room temperature is 30-50 times higher than that of natural rubber.
(8) physiological inertia. Silicone rubber is non-toxic, tasteless and odorless, does not adhere to human tissues, has anticoagulant effect, and has minimal reactivity to human tissues. Is especially suitable as a medical material.
