Abstract

Reinforced articles particularly adapted for use in combination with an adhesive to form reinforced adhesive tape articles that are stretchable as well as hand-tearable along with being highly conformable and cinchable.

First claim

What is claimed is:

1. A conformable reinforced article for use in a reinforced tape, the reinforced article comprising: a backing layer having opposing first and second major surfaces wherein the backing layer is a continuous elastomeric polymeric film and the material of the backing layer is selected from the group consisting of polyolefin elastomers, polypropylene elastomers, polyvinyl elastomers, polyurethane elastomers, and any combination thereof; and, an elastomeric polymeric reinforcing material layer carried along at least one of the first and second major surfaces, wherein the reinforcing material layer is made of a reinforcing scrim material, and wherein the reinforced article exhibits hand-tearability in straight or transverse directions with respect to the length of the article, an elongation extension at break of about 25 to 60%, and a tensile strength greater than about 10 lb/in (17 N/cm) at break.

2. The reinforced article of claim 1 , wherein the tensile strength of the reinforced article is between about 20 to 40 lb/in (35 to 70 N/cm).

3. The reinforced article of claim 2 , wherein the reinforced article exhibits an elastic recovery from about 80 to 90%.

4. The reinforced article of claim 1 , further wherein the backing layer exhibits an elongation extension at break of at least 50%.

5. The reinforced article of claim 1 , further wherein the backing layer exhibits an elongation extension at break of about 300 to 500%.

6. The reinforced article of claim 1 , wherein the reinforcing scrim material is selected from the group consisting of fiberglass, acetate, acrylic, modacrylics, rayon, nylon, polyester, cotton, polyethylene, polypropylene, polyamine, Kevlar, and any combination thereof.

7. The reinforced article of claim 6 , wherein the reinforcing scrim material is made of partially oriented yarn having a drawn down elongation value in a range of from about 30% to about 60%.

8. The reinforced article of claim 7 , wherein the partially oriented yarn reinforcing scrim has a drawn down elongation value in a range of from about 40% to about 55%.

9. The reinforced article of claim 1 , wherein the backing layer has a thickness of about 1.0 mil to about 7.0 mils (0.002 cm to about 0.018 cm).

10. A reinforced adhesive tape article comprising:
a reinforced article including:
a backing layer having opposing first and second major surfaces wherein the backing layer is a continuous elastomeric polymeric film and the material of the backing layer is selected from the group consisting of polyolefin elastomers, polypropylene elastomers, polyvinyl elastomers, polyurethane elastomers, and any combination thereof,
an elastomeric polymeric reinforcing material layer carried along at least one of the first and second major surfaces, wherein the reinforcing material layer is made of a reinforcing scrim material, and
wherein the reinforced article exhibits hand-tearability in straight or transverse directions with respect to the length of the article, an elongation extension at break of about 25 to 60%, and a tensile strength greater than about 10 lb/in (17 N/cm) at break; and

an adhesive layer applied to the reinforcing material layer.

11. The reinforced adhesive tape article of claim 10 , wherein:
the backing layer exhibits an elongation extension at break of about 300 to 500%;
the reinforcing material layer is a partial oriented yarn (POY) scrim having a drawn down elongation of about 60%; and
the reinforced article exhibits an elongation extension at break of 41 to 59%.

12. The reinforced adhesive tape article of claim 10 , wherein the adhesive layer includes a pressure-sensitive material.

13. The reinforced adhesive tape article of claim 12 , wherein the pressure sensitive material is selected from the group consisting of: natural rubber, synthetic rubber, synthetic elastomers, acrylates, and blends thereof.
