Description: U-1923 is a medium to firm density cellular polyurethane foam. This open cell sponge consists of ether polyurethane polymers. U-1923 and its family, have been specially developed for high resiliency and high rebound. This foam has a very low compression set, is breathable, dimensionally stable, and environmentally friendly. U-1923 meets the FMVSS-302 Flammability rating, and has a temperature range of -40° F to 250° F, allowing it to be used in automotive applications.
U-1923’s excellent compression set characteristics and strength allow it to be used in many applications such as automotive, electronic, orthopedic goods, medical and safety equipment. Its low compression set makes it an attractive, economical choice for any application that requires a consistent thickness, such as spacers or fillers.
U-1923’s has a compression deflection @ 25% of 12 +/-3 psi, falling into the medium-firm “3” Grade of ASTM D1056. Other grades can be softer or firmer, depending on application. All cellular urethane products can be supplied with or without adhesive backing in full rolls up to 60" wide, or slit rolls as narrow as ¼". We can also die cut or waterjet cut parts to your exact specifications.
