The liquid silicone rubber (LSR) market is witnessing robust growth, driven by the material’s unique properties and expanding application across industries such as automotive, healthcare, electronics, consumer goods, and industrial manufacturing. Known for its excellent flexibility, high thermal stability, biocompatibility, and chemical resistance, LSR is becoming an essential material for high-performance components and devices.
What is Liquid Silicone Rubber (LSR)?
Liquid silicone rubber is a two-part platinum-cured elastomer that is processed through liquid injection molding (LIM). Unlike traditional rubber or thermoplastics, LSR combines the durability of rubber with the ease of precise, high-speed molding.
Key Applications:
Medical Devices: Due to its biocompatibility and hypoallergenic nature, LSR is widely used in catheters, baby care items, respiratory masks, and wearable health devices.
Automotive Components: LSR’s resistance to extreme temperatures and its ability to seal and dampen vibrations make it ideal for gaskets, connectors, and seals in EVs and fuel systems.
Electronics & Appliances: LSR is used in keypads, insulating elements, LEDs, and cable assemblies due to its excellent dielectric properties.
Consumer Products: Its soft texture and durability make it perfect for kitchenware, baby products, and wearable accessories.
Market Growth Drivers:
Rising Demand in Healthcare: With the global medical devices industry expanding, especially post-COVID-19, the demand for safe and durable materials like LSR has surged.
