(1) High temperature performance. The remarkable feature of silicone rubber is its high temperature stability. it can still maintain at a high temperature above 200°C. Certain flexibility, resilience and surface hardness, and no obvious change in mechanical properties.
(2) Low-temperature performance. The glass transition temperature of silicone rubber is generally -70~-50℃, and the special formula can reach -100℃, indicating its low temperature performance Excellent. This is of great significance to the aviation and aerospace industries.
(3) Anti aging. The Si-O-Si bond in weather-resistant silicone rubber is very stable to oxygen, ozone, and ultraviolet rays. Without any additives, it has excellent weather resistance.
(4) Electrical properties. Silicone rubber has excellent insulation properties, and arc resistance is also very good.
(5) Physical and mechanical properties. The physical and mechanical properties of silicone rubber at room temperature are worse than general rubber, but in At a high temperature of 150°C and a low temperature of -50°C, its physical and mechanical properties are better than general rubber.
(6) oil and chemical resistance. Ordinary silicone rubber has medium oil and solvent resistance.
(7) Gas permeability. At room temperature, the permeability of silicone rubber to air, nitrogen, oxygen, carbon dioxide and other gases is 30-50 times higher than that of natural rubber.
(8) Physiologically inert. Silicone rubber is non-toxic, odorless, odorless, and does not adhere to human tissues. Anticoagulant effect and very little reactivity to body tissues. It is especially suitable as a medical material.
