Abstract: Rigid, closed-cell polyurethane foams are produced by a RIM process by reacting an organic polyisocyanate with an isocyanate-reactive mixture in which a significant amount of a bio-based polyol is present. The foams produced by this process are characterized by improved heat sag and heat distortion temperature.

Abstract: A flexible gastight material for a landfill site includes a component A and a component B, the component A including: at least one of polypropylene glycol with a molecular weight of 600-4000, polytetrahydrofuran diol with a molecular weight of 1000-3000, polycaprolactone diol with a molecular weight of 1000-3000, and polycarbonate diol with a molecular weight of 1000-3000; and at least one of 2,4′-diphenylmethane diisocyanate, 4,4′-diphenylmethane diisocyanate, toluene diisocyanate, isophorone diisocyanate, and hexamethylene diisocyanate. The flexible gastight material for the landfill site provided in the present application has a micro-closed-cell foam structure. The closed-cell elastic structure of the flexible gastight material may block the volatilization of toxic and harmful odors, and may cut off the diffusion path of the odors by combining with gas treatment systems at the landfill site. The flexible gastight material has excellent water blocking and gas sealing performance.
