Liquid silicone rubber (LSR) is a high-purity, two-component platinum-cured elastomer that is flexible, durable, and temperature stable. Unlike normal silicone rubbers, LSR is liquid, making it perfect for injection molding. This allows for the fabrication of complex and intricate shapes with high precision, making it suitable for a wide range of demanding applications. LSR has good biocompatibility, making it suitable for medical devices, as well as outstanding electrical insulating qualities, which are necessary for electrical and electronic components.

Furthermore, LSR is extremely resistant to solvents, UV light, and weathering, ensuring long-term performance in harsh situations. Its adaptability is further improved by its capacity to be colored, transparent, or translucent, and it may be tailored to specific needs such as hardness, tensile strength, and elongation. These properties make LSR a popular material in areas that require dependability and performance, such as automotive, healthcare, consumer products, and construction among others.
