Polyurethane soft foams can typically withstand a wide range of temperatures, unlike thermoplastics and rubber. Polyurethane material can often maintain its original shape and physical properties even in the harshest conditions. The inclusion of acrylate which is a special flame retardant impregnation for fire protection greatly increases the range of applications.
Standard thermoset polyurethanes can typically withstand temperatures between minus 60°C to 95°C. However, some polyurethane chemistries can have a higher tolerance to temperature, as high as 165°C.
