Liquid Silicone Rubber (LSR) has a wide range of applications in the medical, electrical and electronic, food and 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, which include:
1, biocompatibility
After extensive testing, liquid silicone rubber has been shown to have excellent compatibility with human tissue and body fluids. In contrast to other elastomers, liquid silicone rubber resists 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, e-beam and many other techniques.
2. Durability
Liquid silicone rubber parts can withstand extreme temperatures, making them ideal for components under the hood and near the engine in automobiles. Parts made through liquid silicone rubber injection molding are flame retardant and will not melt, which is a serious problem for parts made through plastic injection molding methods.
3, chemical resistance
Liquid silicone rubber is resistant to water, oxidation and certain chemical solutions such as acids and alkalis.
4, high temperature resistance
Molded silicone can withstand a variety of high/low temperature limits compared to other elastomers. For example, Dow Corning's Silastic LSR for continuous use can be stabilized over a temperature range of -60°C to + 180°C.5 Mechanical Properties
5, mechanical properties
Liquid silicone rubber has good elongation, high tear and tensile strength, excellent flexibility and a hardness range of 5 to 80 Shore A. The liquid silicone rubber has good elongation, high tear and tensile strength, excellent flexibility and a hardness range of 5 to 80 Shore A.
6、Electrical properties
Liquid silicone rubber has excellent insulating properties, compared with conventional insulating materials, silicone can work at higher and lower temperatures.
7, transparency and coloration
Liquid silicone rubber has a natural transparency, conducive to the production of colorful products.
