Non-textile polymer compositions and methods
View Patent ↗Included are nylon and polyurethane urea compositions such as in the form of powders, beads and flock to be included in extruded and molded articles containing a thermoplastic resin such as nylon 12. The addition of the powders, beads or flock improve flexibility and shape retention of such molded articles, for example in eyewear frames.
1. An article with improved shock resistance, flexibility and shape retention, said article formed by:
(a) preparing a polyurethane composition in the form of a first mixture comprising:
i) powder and flock or
ii) beads and flock or
iii) powder, beads, and flock;
(b) combining said first mixture with a thermoplastic polymer, wherein the thermoplastic polymer is selected from the group consisting of polyethylene, polycarbonate, polyvinyl chloride (PVC), polymethacrylate, and combinations thereof, to form a second mixture; and
(c) extruding or molding said second mixture in the form of said article.
2. The article of claim 1 , wherein said thermoplastic polymer is polycarbonate.
