Abstract

A hot-melt composition is provided. The hot-melt composition includes thermoplastic polyurethane (TPU) and polyvinylchloride (PVC), the weight ratio of TPU over PVC is in the range of 50/50 to 95/5, and the TPU and PVC together forms at least 50% w of the composition.

First claim

1 . A hot-melt composition comprising thermoplastic polyurethane (TPU) and polyvinylchloride (PVC), wherein the weight ratio of TPU over PVC is in the range of 50/50 to 95/5, the TPU and PVC together forming at least 50% w of the composition.

2 . The composition according to claim 1 , wherein said TPU is selected from the group consisting of polyester-based, polycaprolactam-based, and polyether-based TPU.

3 . The composition according to claim 1 , wherein said PVC has an average molecular weight in the range of 30,000 to 250,000.

4 . The composition according to claim 1 , wherein said composition has melting temperature in the range of 75 to 125°C.

5 . The composition according to claim 1 , wherein said TPU and said PVC together provide the composition.

6 . A flooring product comprising an outer backing provided from the hot-melt composition according to claim 1 .

7 . The flooring product according to claim 6 , wherein the flooring product is selected from the group consisting of synthetic-based flooring products, carpets, and rugs.

8 . The flooring product according to claim 6 , wherein said outer backing has a thickness in the range of 0.5 to 4.0 mm.

9 . The flooring product according to claim 6 , wherein said outer backing is provided as dots, rills, or discrete blotches.

10 . The flooring product according to claim 6 , wherein said outer backing is provided as a substantially uniform layer of hot-melt composition.

11 . The flooring product according to claim 6 , wherein the hot-melt composition is applied by spraying.

12 . The flooring product according to claim 6 , wherein the hot-melt composition covers more than 25% of a lower surface of the flooring product.

13 . A method to provide a flooring product, the method comprising:
providing a flooring product having a first side and a second side; and applying a hot-melt composition to the second side for providing a backing, wherein the hot-melt composition comprises thermoplastic polyurethane (TPU) and polyvinylchloride (PVC), and wherein the weight ratio of TPU over PVC is in the range of 50/50 to 95/5, the TPU and PVC together forming at least 50% w of the composition.

14 . The method according to claim 13 , wherein the hot-melt composition is applied by melting the hot-melt composition and spraying said molten hot-melt composition to the second side of the floor covering.

15 . The method according to claim 14 , wherein the hot-melt composition is applied by melting the hot-melt composition using a hot melt gun.
