Patent ID: 7335416

Claim:
A convex body-side flange of an ostomy device, having formed thereon a layer of a mouldable, pressure-sensitive, hydrocolloid adhesive composition comprising a continuous phase of a mixture of (a) a thermoplastic elastomer, present in an amount of 1-5 wt. % of the composition, (b) a liquid rubber, wherein the weight ratio of thermoplastic elastomer to liquid rubber is 1:0.5 to 1:7, (c) polyisobutylene having a viscosity-average molecular weight of from 35,000-70,000, present in an amount of from 25-45 wt. % of the composition, (d) a low molecular weight liquid polybutene, present in an amount of from 5-20 wt. % of the composition; and a discontinuous phase of one or more water-soluble and/or water swellable absorbent polymers.
