Title:
METHOD OF RECYCLING MOLDED PRODUCT OF FOAM PARTICLES
Document Type and Number:
WIPO Patent Application WO/1994/003323
Kind Code:
A1
Abstract:
A method of recovering reusable foam particles from a molded product of foam particles which is manufactured by using foam particles coated with a thermoplastic resin having a melting point lower than that of the synthetic resin constituting the foam particles, or a solubility different from that of the same synthetic resin, comprising the steps of heating the thermoplastic resin so as to soften or melt the same or dissolving the thermoplastic resin in a solvent, so as the reduce the bonding strength of the foam particles, and separating the foam particles from the molded product by applying a shearing force to the molded product in such a bonding strength-reduced state.
