Silicone Rubber

Description of silicone rubber
        Two component silicone rubber can maintain elasticity for a long time in the temperature range of 65 ~ 250 ℃, and has excellent electrical properties and chemical stability. It can resist water, ozone and climate aging. In addition, it has simple usage and strong process applicability.
        Therefore, silicone rubber is widely used as potting and molding materials. After various electronic and electrical components are coated and potted with room temperature vulcanized silicone rubber, they can play a protective role against moisture (corrosion, shock, etc.). Performance and stability parameters can be improved. Two component RTV silicone rubber is especially suitable for deep potting materials and has faster vulcanization time, which is better than single component RTV silicone rubber.


Application and Advantages of silicone rubber
        Silicone rubber is including food grade silicone, medical grade silicone, skin safe silicone and industry grade silicone, has quite wild applications, such as:

        1. Silicone potting compound for electronic components, such as PCB, circuit board, transformer, connectors, LED, power supplies and so on, or as media for air filter

Advantages:
1) Good adhesion, flame retardant, waterproof, fire proof, insulation, moisture proof, quake-proof/ withstand vibration, thermal conductive, electrical conductive, Antistatic, excellent flow leveling, adjustable working time, good refracting, excellent electrical properties and so on.

2) Compared with epoxy resin, it has better modification ability and electrical insulation ability, high and low temperature resistance, climate aging resistance, ozone resistance, hydrophobia, non-flammability, non-toxic, non-corrosive and physiological inertia, etc.

3) Good cold and heat shock resistance, withstanding the cold and heat shock of - 60 C - 200 C, non-cracking, maintaining elasticity, sealing performance, moisture-proof/waterproof performance is superior.

4) After curing, it is an elastomer with good impact resistance, anti-ultraviolet and anti-atmospheric ageing weatherability, no exothermic heat during curing, little stress on electronic components, insufficient strength and low shrinkage.

5) It can be adjusted into flame retardant, insulating and conductive properties, with silicon-oxygen (Si-O) bond as the main chain structure, which is superior to other filling materials in life, poor adhesion and low strength.

6) It can be operated in all kinds of harsh environments without too much requirement for the environment (Moisture, salt fog, dust, vibration, heat, deep sea, cold, etc.).
