摘要:
This relates variously to techniques for comminuting polymeric foams, to techniques for preparing polymeric foams containing that comminuted foam, and to the resulting comminuted foam powder and polymeric foams. The procedures may be used on foams containing production contaminants such as polyolefins, paper, and foam skins and on other foams containing consumer contaminants such as wood, metal, leather, etc. The comminuted foam powder, with or without contaminants, preferably is screened or sifted to obtain a foam powder having a particle size of about 2 mm or less.
摘要:
The embodiments of the invention are directed to a composite material comprising a fiber reinforcing material, a binder resin and polyurethane foam particles. Other embodiments are related to a process for manufacturing a composite material comprising a fiber reinforcing material, a binder resin and polyurethane foam particles, the method comprising depositing the binder resin and polyurethane foam particles the fiber reinforcing material to form a composite precursor and treating the composite precursor to form the composite material
