## Abstract

An adhesive bandage composition uses a blend of polyisobutylene, polybutene, butyl rubber with reinforcing fiber, filler material and zinc oxide blended under heat and rolled into a thin sheet. The sheet of adhesive material can be attached to a bandage material on one side and covered with a protective paper on the other and cut to shape for application to a body surface.

## Claims

### Claim 1

An adhesive bandage material adapted to be formed into sheet material and applied to a bandage cloth comprising:
a blend of 20-35% by weight of polyisobutylene and polybutene;
5-15% by weight of butyl rubber;
1-10% by weight of reinforcing fibers of aromatic polyamide fibers;
1/2-4% by weight of zinc oxide;
talc filler material; and
ethyl alcohol to thereby form a viscous material capable of being formed in a sheet for attachment to bandage cloth.

### Claim 2 (depends on 1)

The adhesive bandage material in accordance with claim 1, including 30-60% by weight of talc filler.

### Claim 3

An adhesive material composition comprising:
a blend of about 15% by weight of polyisobutylene and about 20% by weight of polybutene with about 10% by weight of butyl rubber, aromatic polyamide fibers, filler material, 1/2-4% by weight of zinc oxide and ethyl alcohol.

### Claim 4 (depends on 3)

An adhesive material in accordance with claim 3, which includes 50% by weight of talc filler, 3% by weight of reinforcing fiber and 2% by weight of zinc oxide.
