摘要 |
<p>Production of a polyurethane integral foam involves reaction of an isocyanate component comprising (i) an optionally modified organic polyisocyanate and/or its pre-polymer and (ii) an inorganic zeolite with a specified polyol composition : Production of a polyurethane integral foam involves reaction of an isocyanate component comprising (i) an optionally modified organic polyisocyanate and/or its pre-polymer and (ii) an inorganic zeolite with a polyol composition comprising (A) a polyol of hydroxy number 20-1050 (especially 200-900) and functionality 2-6 (especially 2-5) and/or a mixture of polyols with calculated average OH number 250-650 (especially 350-500) and calculated average functionality 2.5-5 (especially 3-4.5); (B) water; and optionally (C) chain- extenders, crosslinkers, activators and/or conventional additives.</p> |
