Abstract
The present invention is directed to a process for forming a thermoplastic composition from carpet wherein a carpet sample are melt blended without separating the carpet into its component parts. The process of the present invention produces a thermoplastic composition useful as a substitute for virgin thermoplastics in a variety of applications.
Claims7
A process for forming a thermoplastic composition from at least one carpet sample comprising a plurality of polymeric components, said sample including a plurality of nylon tufts, at least one polyolefin backing and styrene-butadiene rubber adhesive, said process comprising the steps of:
- (a) providing at least one unseparated carpet sample;
- and
- (b) melt blending said unseparated carpet sample under conditions of temperature, pressure and intensive mixing sufficient to produce a thermoplastic composition wherein all of said polymeric components are reduced to a flowable liquid form.
