Liquid silica gel (LSR) is widely used in medical, electronic and electrical, food, mother and baby industries due to its many advantages such as heat and weather resistance, non-toxicity, electrical insulation, biocompatibility, colorless and transparent, and tear resistance. Liquid silicone rubber is an ideal material for very demanding applications due to its unique properties, including:

1. Biocompatibility
After extensive testing, liquid silicone rubber has proven to have excellent compatibility with human tissues and body fluids. Compared with other elastomers, liquid silicone rubber can resist bacterial growth and will not contaminate or corrode other materials. LSR is odorless and tasteless and can be sterilized by a variety of methods, including steam autoclaving, ethylene oxide (ETO), gamma, electron beam and many other techniques.

2. Durability
Liquid silicone rubber parts can withstand extreme temperatures, which makes them ideal for components under the hood and near the engine. Parts manufactured by injection molding of liquid silicone rubber are flame retardant and will not melt, which is a serious problem for parts manufactured by plastic injection molding.

3. Chemical resistance
Liquid silicone rubber is resistant to water, oxidation and certain chemical solutions, such as acids and alkalis.

4. High temperature resistance
Compared with other elastomers, molded silicone can withstand various high/low temperature extremes. For example, Silastic LSR, which is continuously used by Dow Corning, can be stable in the temperature range of –60°C to +180°C.

5. Mechanical properties
Liquid silicone rubber has good elongation, high tear strength and tensile strength, excellent flexibility and a hardness range of 5 to 80 Shore A.

6. Electrical performance
Liquid silicone rubber has excellent insulating properties. Compared with conventional insulating materials, silicone can work at higher and lower temperatures.

7. Transparency and pigmentation
Liquid silicone rubber has natural transparency, which is conducive to the production of colorful products.
