Abstract
A tear and fatigue resistant gel article comprising two or more communicating internal volumes like cavities when depressed by external pressure or force is capable of collapsing unto itself in a controllable and directionally preselected manner by venting static air within said internal through openings in said gel article, said gel article is made from gel compositions having rigidity of from about 20 gram Bloom to about 1,800 gram Bloom suitable for cushioning and other uses.
Claims7
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 styrene-isoprene/butadiene-styrene block copolymer(s) and (2) hydrogenated controlled distribution styrene-isoprene/butadiene-styrene block copolymer(s);
- (III) said gel article having two or more internal directionally collapsible cavities in connecting communication through one or more openings to an external surface of said gel article.
