Abstract

Hermetic rigid cellular material based on polyvinyl chloride is prepared by homogeneously mixing a resin having polyvinyl chloride as the main constituent, an organic isocyanate, an organic acid anhydride and less than 5%, based on the weight of the resin, of a heat decomposable blowing agent; heating said mixture in a mould under pressure; cooling and removing the material from the mould; and placing the material in a warm chamber at 90 DEG -100 DEG C. in the presence of water vapour. Plasticizers, colouring materials and stabilizers may also be included in the expandable mixture. In an example, a cellular material is prepared from a paste comprising polyvinyl chloride, toluene diisocyanate, phthalic anhydride, azoisodibutyric dinitrile, calcium carbonate and an oil resulting from the distillation of mineral oil.ALSO:Hermetic rigid cellular material based on polyvinyl chloride is prepared by homogeneously mixing a resin having polyvinyl chloride as the main constituent, an organic isocyanate, an organic acid anhydride and less than 5%, based on the weight of the resin, of a heat decomposable blowing agent; heating said mixture in a mould under pressure, cooling and removing the material from the mould, and placing the material in a warm chamber at 90-100 DEG C. in the presence of water vapour.
