basic information
Characteristics of Urethane Foam and Urethane Sponge Urethane foam is made primarily from polyols and polyisocyanates, mixed with foaming agents, stabilizers, catalysts, colorants, and other components, and is foamed while being polymerized. The type that has interconnected bubbles, is soft, and has good resilience is called "soft urethane foam." Urethane foam can be classified into two types: "ether-based" and "ester-based," depending on the type of polyol used. Ether-based Urethane <Features> Compared to ester-based, it is lightweight and has greater physical strength, such as tensile strength. It has excellent cushioning properties. It is chemically stable against water. It has excellent chemical resistance. Applications: Furniture, bedding, automobiles, etc. Ester-based Urethane <Features> It has superior mechanical strength compared to ether-based. It has excellent sound-absorbing properties. It has excellent oil resistance and abrasion resistance. Applications: Acoustics, building materials, various industrial materials.
