POLYESTER RESINS FOR POLYURETHANE FOAMS |
摘要 |
<p>The machine processing character as well as the stress-strain properties of polyester polyurethane foam are improved by the use of a cross-linking polyol, a viscosity increasing dicarboxylic acid or anhydride such as phthalic anhydride, and by the use of specific minor amounts of poly(oxyethylene) glycol, in the esterification formula of foam grade polyester resins. A nonhydrophillic flexible polyester based polyurethane foam is produced.</p> |
