POLYURETHANE BASED GEL COMPOSITION

摘要

A polyurethane gel for comfort applications includes a reaction product of a composition that includes (1) from 5 wt% to 35 wt% of a prepolymer component, based on a total weight of the composition, the prepolymer component including a reaction product of an isocyanate component that includes diphenylemethane diisocyanate (MDI) and a polyol component that includes a polyoxyethylene - polyoxypropylene polyol that has an polyoxyethylene content greater than 65 wt%, based on a total weight of the polyoxyethylene polyoxypropylene polyol, and (2) a remainder of a prepolymer-reactive component that includes an amine-terminated polyol and a propylene oxide-ethylene oxide based monol or polyol. The composition excludes any plasticizers.
