What is Liquid Silicone Rubber?
Silicone Rubber is widely accepted terminology used among in the synthetic rubber industry. Similarly, the terms such as liquid silicone rubber molding, liquid silicone rubber injection molding, liquid silicone molding, silicone liquid molding, liquid silicone injection molding, silicone injection molding, LIM molding, silicone rubber molding and silicone molding are all used frequently and mostly interchangeably.
Liquid silicone rubber (LSR) is very low viscosity silicone that can be intended for use in liquid injection molding (LIM) equipment or cast into silicone rubber sheets. LSRs are generally injection molded or cast while gum based silicones are typically compression molded.
LSR Characteristics
1.Biocompatibility
Under extensive testing, liquid silicone rubber has demonstrated superior compatibility with human tissue and body fluids.
In comparison to other elastomers, LSR is resistant to bacteria growth and will not stain or corrode other materials.
LSR is also tasteless and odorless and can be formulated to comply with stringent FDA requirements.
The material can be sterilized via a variety of methods, including steam autoclaving, ethylene oxide (ETO), gamma, e-beam and numerous other techniques.
2. Durable
LSR parts can withstand extreme temperatures, which makes them an ideal choice for components under the hood of cars and in close proximity to engines. Parts fabricated via liquid silicone rubber injection molding are fire-retardant and will not melt.
3. Chemical resistance
Liquid silicone rubber resists water, oxidation and some chemical solutions such as acids and alkali.
4. Temperature resistance
Compared to other elastomers, silicone can withstand a wide range of high/low temperature extremes.
5. Mechanical properties
LSR has good elongation, high tear and tensile strength,excellent flexibility and a hardness range of 5 to 0 Shore A.
6. Electrical properties
LSR has excellent insulating properties, which offer an appealing option for a host of electrical applications. Compared to conventional insulating material, silicone can perform in far higher and lower temperatures.
7. Transparency and pigmentation
LSR possesses a natural transparency, which makes it possible to produce colorful, custom, & molded products.
