Blended silicone rubber is a kind of synthetic rubber with excellent comprehensive performance, which can be widely used in aviation, cable, electronics, electrical appliances, chemical industry, instrumentation, cement, automobile, construction, food processing, medical devices and other industries, as well as for molding, extrusion and other mechanical deep processing.

Blended silicone rubber has the following characteristics:

1. It has chemical stability, weather aging resistance, radiation resistance, physiological inertia and good air permeability.

2. It has excellent thermal stability, high and low temperature resistance, can work under -60 ℃ ~ +250 ℃ for a long time, ozone resistance, weather resistance, good electrical performance, and strong resistance to corona, arc and spark.

3. It has excellent oil resistance and good processability.

4. Excellent high and low temperature resistance, can be used for a long time in the range of -60 ℃ ~ +20 ℃.

5. With excellent mechanical properties and aging resistance, it can be used to manufacture all kinds of oil resistant seals, oil seals, etc.

Silicone rubber compound is a kind of synthetic rubber with excellent comprehensive performance. It is made by adding silicone rubber raw rubber to double roll rubber mixer or closed kneader, gradually adding white carbon black and other additives, repeatedly refining evenly, and mixing according to the technical requirements of users' products. It is mainly used for molding and extrusion products processing.

Silicone compound has excellent thermal stability, high and low temperature resistance, can work under -60 ℃ ~ +250 ℃ for a long time, ozone resistance, weather resistance, good electrical properties, strong resistance to corona, arc and electric spark, chemical stability, weather aging resistance, radiation resistance, physical inertia and good permeability. It can be widely used in aviation, cable, electronics, electrical appliances, chemical industry, instrumentation, cement, automobile, construction, food processing Medical devices and other industries are used for deep processing of molding, extrusion and other machinery.

Batch compounding process of mixed silicone rubber batch compounding process is used to prepare mixed silicone rubber in kneader and internal mixer. In industrial production, in order to produce mixed silicone rubber in large quantities, large kneaders equipped with two mixing paddles are often used, with a capacity of several cubic meters; In order to mix the raw materials uniformly, a long mixing time is required. Mixing silicone rubber adopts an internal mixer equipped with two propellers in the tank and a pressurized block on the upper part, which can make the raw materials mixed in the compressed state, and can produce evenly mixed silicone rubber in a short time.
