GEL PAD, MANUFACTURE AND USE

A gel of specific composition is encased in a flexible elastic casing to form a gel pad. The gel used is made up of (a) 15-62 weight % (based on (a)+(b)) of a high molecular weight covalently cross-linked polyurethane matrix and (b) 85-38 weight % (based on (a)+(b)) of a liquid dispersing agent. The...

Zusammenfassung:	A gel of specific composition is encased in a flexible elastic casing to form a gel pad. The gel used is made up of (a) 15-62 weight % (based on (a)+(b)) of a high molecular weight covalently cross-linked polyurethane matrix and (b) 85-38 weight % (based on (a)+(b)) of a liquid dispersing agent. The liquid dispersing agent is a polyhydroxy compound having an average molecular weight between 1000 and 12,000, and an OH number between 20 and 112. This dispersing agent contains essentially no hydroxy compounds with a molecular weight below 800. The gel may also include fillers and/or additives known to those in the art. Suitable casing materials include polyurethane films, woven fabrics, knitted fabrics, and mesh fabrics. These gel pads are particularly useful as mattress, mattress inserts, wheelchair cushions, car seats, car seat supports and as pad elements for upholstered furniture.
