Hard foam is a polyether-based polyurethane foam engineered for enhanced firmness and durability. Offering a high load-bearing capacity, it delivers superior structural support while retaining essential flexibility. This foam can be easily die-cut, milled, and laminated with other materials, making it highly versatile for applications that demand strength and resilience. Additionally, our 40-hard foam grade provides excellent acoustic damping properties, making it particularly well-suited for high-KVA generator sets and refrigeration equipment.
