Abstract
The invention is a laminate and a method for making the laminate, where the laminate has good scuff resistance, good abrasion resistance, good low temperature properties, and excellent resistance to delamination. The laminate is constructed of a polyurethane primer coated scrim fabric that is laminated to a cast extruded compounded PVC film. The film composition is predominately polyvinyl chloride (PVC), a thermoplastic polyurethane polymer (TPU), and a polytetrafluoroethylene micronized wax. The method for forming the laminate is a) providing a compounded PVC and a primer coated scrim fabric; b) extruding the compounded PVC forming a cast extruded compounded PVC film; and c) laminating the compounded PVC film to the primer coated scrim fabric.
Claims30
A laminate, comprising:
- a primer coated scrim fabric;
- and a cast extruded compounded PVC film, wherein said cast extruded compounded PVC film is comprised of:
- a thermoplastic polyvinyl chloride polymer (PVC), a thermoplastic polyurethane polymer (TPU), and a fluoroethylene polymer.
A method for forming a laminate having superior scuff and abrasion resistance, said method comprising the steps of:
- a) providing a compounded PVC, where said compounded PVC comprises a thermoplastic polyvinyl chloride polymer (PVC), a thermoplastic polyurethane polymer (TPU), and a fluoroethylene polymer;
- b) extruding the compounded PVC forming a cast extruded compounded PVC film;
- and
- c) laminating the compounded PVC film to a scrim fabric having a polyurethane primer coating.
A method for forming a laminate having superior scuff and abrasion resistance, said method comprising the steps of:
- a) providing a compounded PVC film, where said compounded PVC film is comprised of PVC, TPU, and a fluoroethylene polymer;
- b) providing a scrim fabric with a polyurethane primer coating;
- c) providing an extrudable adhesive comprised of PVC and TPU;
- d) extruding the adhesive through a die onto a two roll nip to which is fed the compounded PVC film and the primer coated scrim fabric, where said die has a compression roll and a steel roll, and wherein said primer coated scrim fabric partially wraps the compression roll;
- and
- e) laminating the compounded PVC film to the primer coated scrim fabric.
