Liquid Silicone Rubber (LSR) is a highly elastic polymer composed of silicone units. At room temperature, LSR exists in a liquid state and can solidify into a durable material when heated.
It is often injected into silicone mold cavities to produce various high-precision components. Generally, liquid silicone rubber has low compression, good stability, and can withstand extremely high and low temperatures.
This material is frequently used to create gaskets, membrane seals, electrical connectors, multi-pin connectors, baby products requiring smooth surfaces, kitchen utensils, and more.
Properties of Liquid Silicone Rubber:
- Odorless and Tasteless: LSR has no odor or taste, making it ideal for manufacturing food, beverage, and child-friendly products.
- Mechanical Properties: LSR features excellent elongation, tensile strength, tear strength, and remarkable flexibility.
- Durability: LSR parts have a long lifespan, are wear-resistant, and withstand extreme temperatures, making them suitable for outdoor applications.
- Chemical Resistance: LSR is resistant to water, oxidation, and certain chemical solutions such as acids and bases. It can also be sterilized by various methods.
- Heat Resistance: LSR can endure both high and low temperatures without deformation or damage.
- Biocompatibility: LSR is compatible with human tissue and body fluids, is hypoallergenic, non-toxic, and resistant to bacterial growth.
- Electrical Properties: LSR exhibits excellent insulation properties, beneficial for various electrical applications. Silicone can operate at much higher and lower temperatures than traditional insulating materials.
- Transparency and Pigmentation: Liquid silicone rubber is naturally transparent. Its base color is white, making it suitable for coloring, allowing for the production of custom-molded items in a wide range of aesthetically pleasing colors.
- Ease of Processing: It can be easily processed by various methods, including molding, injection molding, and coating.
- Dimensional Stability: It has high dimensional stability, with minimal deformation over time.
