METHOD OF PRODUCING A SURFACE PROTECTION COMPOSITE |
摘要 |
The present invention provides a method of making a three-layer aliphatic thermoplastic polyurethane (TPU); surface protection composite. The method involves extruding- an aliphatic thermoplastic polyurethane (TPU) layer onto a substrate layer at the flat die extrusion nip -comprising a rubber roller in the back position and. a steel, roller in the front position; cooling the extruded aliphatic: thermoplastic polyurethane; feeding the two-layer thermoplastic polyurethane (TPU) composite film into a downstream nip comprising at least one rubber roller; and laminating a flexible polymer interleaf film onto the exposed thermoplastic polyurethane (TPU) side of the two-layer composite under pressure in that nip. The surface protection, composite of the present invention; may be included in a variety of products for use in automotive, electronics: or furniture applications |
