Liquid Silicone Rubber For Silicone Sponge
Liquid Silicone Rubber (LSR) for silicone sponge employs a foaming system and various molding methods (extrusion, compression, injection) to produce lightweight, resilient foam structures offering shock absorption, waterproof sealing, weather resistance, and soft comfort. Widely used in gaskets, medical devices, vibration-damping components, and food-contact applications, it allows formulation and foaming adjustments to achieve different hardness levels and rebound properties. As a result, these products maintain long-term stability and durability across a broad temperature range and in both indoor and outdoor environments.
