Silicone Foam

Silicone foam is manufactured using platinum-cured liquid silicone rubber. The raw compound is foamed on a continuous calendering production line and then thermally cured. By varying the formulation ratios and curing parameters, silicone foam products with different densities, softness/hardness, and cell structures are created. Silicone foam typically has a smooth skin surface, which is a result of the production process. Open-cell silicone foam is widely used for cushioning, dust sealing, or light sealing applications. Closed-cell silicone foam is used for outdoor gaskets, flush gaskets, and resilient cushioning pads.
