Purchase this item and get PU28 is a low-density open-cell polyurethane foam with a density of approximately 28 kg/m³. While soft, it sits toward the higher end of the low-density PU foam range, giving it improved durability and resistance to breakdown compared to lighter foams.
Its structure provides reliable cushioning and moderate firmness, making it suitable for lining cases that protect frequently handled yet delicate items such as instruments or technical equipment. The foam compresses easily while maintaining enough resilience to hold items securely in place.
In addition, its open-cell composition allows it to function as an entry-level acoustic absorption material, helping to reduce echo and ambient noise.
