Abstract
Official abstract text for this publication.
A foam-molded polyurethane foam for a seat pad, particularly for a vehicle, that reduces both shakiness and stress relaxation is provided. The polyurethane foam contains a foaming liquid containing (A) a polyol, (B) a polyisocyanate, (C) water and (D) a catalyst. The polyol (A) contains from 40 to 50% by mass of (a-1) a polyether polyol having a molar ratio of repeating units derived from ethylene oxide and propylene oxide of from 5/95 to 25/75 and a number average molecular weight of from 6,000 to 8,000, and from 5 to 15% by mass of (a-2) a polyether polyol having a molar ratio of repeating units derived from ethylene oxide and propylene oxide of from 0/100 to 20/80 and a number average molecular weight of from 600 to 2,000. The amount of water (C) is 2.0 parts by mass or more per 100 parts by mass of the polyol (A).
First claim
Opening claim text (preview).
The invention claimed is: 1. Polyurethane foam for a seat pad, comprising a foaming liquid containing (A) a polyol component, (B) a polyisocyanate component, (C) water and (D) a catalyst, which has been foam-molded, wherein the polyol component (A) contains from 40 to 55% by mass, based on the polyol component, of (a-1) a polyether polyol, which is obtained through ring-opening polymerization of ethylene oxide and propylene oxide, having a molar ratio of repeating units derived fr…
