Abstract: A polyurethane foam is obtained by reacting total amount of (cyclo)aliphatic isocyanate with a portion of compound (B) containing 2 or more isocyanate-reactive hydrogen atoms to give prepolymer which is reacted with remaining compound (B), or vice-versa. The foam has yellowness index, based on ASTMD 1925-70 of less than 30 and tensile strength based on DIN 53571 of 60 kPa or more. Independent claims are included for the following: (1) preparation of polyurethane foam by the above mentioned reaction; and (2) use of polyurethane foam.
