GK-300 Silicone Foam | Matte Surface Flame Retardant Gasket Material

The GK-300 silicone foam is a soft silicone sponge material specially formulated for fabricating high-performance gaskets, seals, cushions, and fire stops that need to meet strict reliability requirements for extreme temperature, flame retardancy, non-toxicity, or other demanding conditions. Engineered with resistance to environmental extremes, plus mechanical resilience and safety features, this material is widely used in transportation equipment, communications enclosures, electronic products, industrial machinery, and home appliances. The GK-300 silicone foam is available in two surface types: matte (standard) and glossy. The matte surface offers a consistent, professional finish ideal for visible sealing applications. The glossy surface provides a degree of slip resistance, making it suitable for applications where enhanced grip is required. The material can be custom fabricated to customer specifications, including die-cutting for custom shapes and dimensions.
