*The physical properties listed above are obtained by conducting tests according to ASTM D -1564. The flame retardant property is obtained by using the test method U.L. 94, standard for safety. The rating is 94 HF – 1 U.L. 94 is to be used as a small scale / laboratory comparative test and is not intended for use as a fire hazard rating. Polyurethane foams containing a flame retardant additive will burn.
