Abstract

1411958 Fibre-containing foamed laminates BAYER AG 21 Dec 1972 [23 Dec 1971] 59118/72 Heading B5N [Also in Division C3] Foamed laminated plates are prepared by pouring on to a stack of fibre mats, each consisting of glass fibre or the middle one consisting of sisal or polyamide and the outer ones of glass silk, a mixture which forms upon reaction a hard foamed polyurethane resin which can be reversibly hot formed and which comprises a biuret polyisocyanate prepared by adding water to an isomeric mixture of tolylene-diisocyanate containing castor oil polyglycol ether and then heating; a polyether which is the reaction product of bisphenol A and propylene oxide, subsequently reacted with ethylene oxide, water as blowing agent, a silicone foam stabilizer, triethylamine or dibutyl tin dilaurate as catalyst, and completing the reaction in a mould by heating. The moulding may be carried out between ABS cover foils.
