"Skinless sponge" is a revolutionary extruded sponge product that does not have the accompanying surface layer (skin layer) typically found in extruded molded products.
Inquire About This Product
basic information
Typically, sponge products made from extruded materials using a linear hot air vulcanization device always form a skin layer on the surface during molding with high-temperature hot air. "Skinless sponge" is a revolutionary product that overturns this basic concept. Despite lacking a skin layer, its unique foaming structure results in low water absorption, effective thermal insulation, soundproofing, and excellent shock absorption. Additionally, because conventional sponge products have a skin layer, drilling holes with tools like drills can cause the material to wrap around, requiring pre-punching before drilling. However, since there is no skin layer, it can be processed directly with drills, allowing for cost reduction in processing. The material can be EPDM, with a hardness of approximately 40° (JIS E).
