Abstract:
A moldable heterogeneous composite material has a continuous plastic phase ( ) and a discrete phase of unground rubber ( ) dispersed in the continuous phase. The composite material can be formed from thermoplastic or thermosetting materials and pieces of rubber from used tires. The composite material of the present invention can be molded in a process having the steps of providing a flowable melt of plastic material ( ), providing unground rubber pieces ( ), mixing the plastic material with the rubber pieces to form a composite material, and molding the composite material into an article ( ) having a desired shape. Molded articles formed from the composite of the present invention have high rigidity and good durability.
