APG 0731FIRM - Firm Density Red Silicone Closed Cell Sponge is a versatile and durable material that is often used in gasketing applications where a soft, compressible material is needed. This makes it an excellent choice for gasketing applications that require a material that is able to withstand high levels of heat and pressure. In addition to its excellent thermal and mechanical properties, closed cell sponge silicone also offers good resistance to chemicals and other environmental factors, making it a versatile and reliable choice for a wide range of applications.
