Silicone rubber compound is a kind of 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 spark, chemical stability, weathering resistance, radiation resistance, physiological inertia, good air permeability, can be widely used in aviation, cables, electronics, electrical appliances, chemicals, instruments, cement, automobiles , construction, food processing, medical equipment and other industries, used for mechanical deep processing such as molding and extrusion.

The mixed rubber is made by adding silicone rubber raw rubber to a double-roll rubber mixing machine or a closed kneader and gradually adding silica, silicone oil, etc. and other additives for repeated refining.

According to the different fillers and additives added, the performance of silica gel is also different. Mainly 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 so on.

The molding of the mixed rubber requires the application of a certain temperature and pressure under the action of the vulcanizing agent (it is only required for the solid state, the purpose is to prevent the generation of air bubbles). For example, HTV needs to be around 165°C, and LSR needs to be around 140°C.
