ABSTRACT:
Flexible polyurethane foams are anchored to themselves or to other compatible thermoplastic materials by the application of pressure and heat to such foams which contain at least 50 parts by weight per 100 parts of polyol in the foam formulation of at least one solid theromplastic resin composition having a particle size greater than 18 mesh (1.0 mm. sieve opening) and no larger than about 21/2 mesh (about 8 mm. sieve opening), preferably in the range of 16 mesh (1.2 mm. sieve opening) to 8 mesh (2.4 mm. sieve opening), in the U.S. Sieve Series.
