PRODUCTION OF FLAME-RETARDANT REBONDED FOAM

摘要

The present invention is directed to a method of producing flame-retardant rebonded foam by bonding the chips of polyurethane foam with one another using a urethane adhesive, characterized by adding 15 to 40 parts by weight of thermally expansible graphite as the flame retarder to 100 parts by weight of the chips. The obtained rebonded foam has a remarkably excellent flame retardancy.
