Liquid silicone rubber (LSR) is a polysiloxane-based liquid elastomer material that forms a high-performance elastomer through cross-linking and curing. Its core advantages lie in the ease of liquid processing and the exceptional performance of the cured material. LSR has become a key material in high-end manufacturing, biomedicine, electronics, and other fields.
As a high-performance elastomeric material, liquid silicone rubber has superior properties: excellent high and low temperature resistance, radiation resistance, aging resistance, chemical resistance and weather resistance, flame retardancy, non-toxic combustion products, high tear resistance, low compression deformation, electrical insulation and conductivity, odorless and tasteless, good mechanical strength and processing performance. It can also be modified with additives to obtain other properties.
Core Performance Advantages
Adaptable to Extreme Environments, Meeting Diverse Needs
1. Liquid Processing, Efficient Molding
Excellent fluidity enables automated production through injection, extrusion, and casting processes, eliminating the need for traditional rubber mixing and vulcanization steps and reducing scrap.
Suitable for complex structures and high-precision products (e.g., micron-level parts), such as medical catheter connectors and electronic connectors.
2.Wide Temperature Stability and Strong Weather Resistance
Operating Temperature Range: -60°C to 200°C (Special formulations can reach over 300°C), maintaining elasticity even in extreme temperatures.
Resistant to UV and ozone degradation, suitable for outdoor or harsh environment applications (e.g., aerospace seals and automotive engine compartment components).
3. Adjustable Mechanical Properties, Versatile Functionality
A wide hardness range (Shore hardness 10A to 80A), with fillers to adjust strength and wear resistance.
High elongation (300% to 800%) and tear resistance make it suitable for applications requiring flexibility (e.g., wearable device buttons and flexible sensor packaging).
4. Safe, environmentally friendly, and highly adaptable.
Addition-molded LSR releases no byproducts and complies with food contact and medical standards, including those of the FDA and ISO 10993.
It offers excellent electrical insulation (dielectric constant as low as 2.5) and chemical resistance (acids, alkalis, and oils), making it suitable for electronic and electrical packaging.
