Silicone rubber compound is a synthetic rubber with excellent comprehensive properties. It has excellent thermal stability, high and low temperature resistance, can work for a long time at -60℃～＋250℃, anti-ozone, weather resistance and good electrical properties, strong resistance to corona, arc, and electric spark, and chemical stability , weather resistance, radiation resistance, physiological inertia, good air permeability, can be widely used in aviation, cables, electronics, electrical appliances, chemicals, instrumentation, cement, automobiles, construction, food processing, medical equipment and other industries, and used for molding, extrusion and other machinery deep processing.
The silicone rubber compound manufactured by SiSiB Silicone China is made by adding raw silicone rubber to a two-roll rubber mixing machine or a closed kneader by gradually adding white carbon black, silicone oil, and other additives.
According to the different silicone additives and fillers added, the performance of silica gel is also different. Mainly manifested in: physical properties (hardness, tensile strength, elongation, tear strength, shrinkage, plasticity, specific gravity), electrical properties, chemical stability (temperature resistance, weather resistance, acid and alkali corrosion resistance) and other aspects.
The molding of the rubber compound requires a certain temperature and pressure to be applied under the action of the vulcanizing agent (only required for the solid state, the purpose is to prevent the generation of bubbles). For example, HTV should be around 165°C, and LSR should be around 140°C.
