One of the most commonly used lead wires in motors is the JG silicone rubber lead wire, which is widely applicable in view of the diversified characteristics of its insulating materials. Such as high temperature suitability, low temperature suitability, weather resistance, impregnation resistance, insulation properties and good physical properties, today to share with you the main performance characteristics of silicone rubber.


Low temperature performance. The glass transition temperature of silicone rubber is generally -70~-50 ° C, and the special formula can reach -100 ° C, indicating that its low temperature performance is excellent. This is of great significance to the aviation and aerospace industry.


High temperature performance. The remarkable feature of silicone rubber is high temperature stability, although the strength of silicone rubber at room temperature is only half of natural rubber or some synthetic rubber, but in the high temperature environment above 200℃, silicone rubber can still maintain a certain flexibility, resilience and surface hardness, and mechanical properties have no significant change.


Weather resistance Silicone rubber has excellent weather resistance without adding any additives.


Electrical insulation properties. Silicone rubber has excellent insulation properties, corona resistance and arc resistance are also very good.


Good physical and mechanical properties. The physical and mechanical properties of silicone rubber at room temperature are worse than that of general rubber, but at high temperatures of 150 ° C and low temperatures of -50 ° C, their physical and mechanical properties are better than that of general rubber.


Corrosion resistance and gas permeability. Silicone rubber has oil resistance and chemical reagent properties; 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.
Physiological inertia. Silicone rubber is non-toxic, tasteless, odorless, non-adherent to human tissue, has an anticoagulant effect, and has very little reactivity to body tissue. Especially suitable for use as medical materials.
