Closed Cell Foam Manufacturer | EVA, PE, EPDM Solutions

As a closed cell foam manufacturer with decades of expertise, we control the entire expansion process for EVA, PE, EPDM, and TPE materials, resulting in foams with independent, non-interconnecting cells that provide exceptional buoyancy, thermal insulation, and compression resistance. Our manufacturing capabilities include continuous sheet extrusion for uniform thickness up to 50mm and compression molding for complex shapes like seals or bumpers. We regularly supply closed-cell foam to industries where moisture exclusion is critical, such as marine fendering, outdoor sport flooring, and agricultural tank insulation. Furthermore, we offer customized cell sizes, from fine (0.1mm) for smooth surfaces to coarse (1mm) for high compressibility, enabling engineers to fine-tune performance. Our in-house testing lab measures water absorption (typically <0.1% by volume), thermal conductivity, and recovery after repeated loading, ensuring each batch meets application-specific requirements before shipping to clients in the footwear, packaging, or construction sectors.
