Abstract:
1. A gel article comprising a soft gelatinous elastomer composition formed from (I) 100 parts by weight of one or a mixture of two or more block copolymer(s); and (II) about 250 to about 1,600 parts by weight of one or more selected plasticizer(s) being in sufficient amounts to achieve a gel rigidity of from about 20 gram Bloom to about 1,800 gram Bloom; said block copolymers selected from one or more (1) hydrogenated poly(styrene-isoprene/butadiene-styrene) block copolymer(s) comprising poly(styrene-ethylene/ethylene-propylene-styrene) and (2) hydrogenated controlled distribution poly(styrene-butadiene-styrene) block copolymer(s) comprising poly(styrene-ethylene-butylene-ethylene-butylene/styrene-ethylene-butylene-styrene); (III) said gel article comprising one or more arrays of two or more internal directionally collapsible cavities, said arrays selected from one or more of the group of radial arrays, sun burst arrays, slanted arrays, anti-symmetric arrays, off-centered arrays, symmetric arrays, random arrays, and selected profile arrays, said arrays capable of directionally collapsing under a selected pressure load applied to said gel article.
