Liquid Silicone rubber(LSR) is a kind of non-toxic, heat resistant, high resilience flexible thermosetting transparent organic silica-gel, its sulfur change behavior is mainly manifested as low viscosity, rapid curing, shear thinning, and high thermal expansion coefficient. Two-component liquid silicone rubber with high transparency, high strength, and tear resistance is suitable for the injection molding process.
The comprehensive use of silicone in the market because it will not release toxic substances and soft and comfortable touch, has high temperature and low temperature (-60C ~+ 300C), and has good physical and chemical properties. Strong elasticity, superior leakproofness, excellent electrical insulation, and resistance to chemicals, fuel, oil, and water drive silicone to be a good material for coping with an adverse environment.

Silicone typically can distinguish between solid and liquid. The processing method of solid silicone mainly takes thermal transfer, however, liquid silicone rubber prefers injection molding. Liquid silicone rubber(LSR) on the investment in equipment and raw material cost is high, but the superiority of fast production speed, low degree of processing, and low rate of material waste are the major reasons for liquid silicone injection molding in the pursuit of precision, speed, automation industry. Liquid silicone rubber injection molding undoubtedly be the new trend in the silicone industry.

Under various applications and different level of hardness, liquid silicone rubber mainly includes:

Silicone rubber is commonly founded in the manufacturing of custom LSR parts. LSR parts are applied in many industries, including Automotive, Medical, Life & Science, etc. Its flexible hardness and resistance make them a good choice for gaskets and o-rings. Their conductivity makes them ideal for seals, LED lighting, and touchpad. Its waterproof, oil and chemical resistance, and temperature endurance offer suitable situation for automotive and aerospace components.
