PROCESSO PARA A PREPARACAO DE UM CORPO DE MOLDAGEM DE POLIVINILBUTIRAL E FOLHAS ASSIM PREPARADAS
A polyvinylbutyral moulding is produced by extruding a moulding composition containing polyvinylbutyral, plasticiser, a phenolic stabiliser and a triester of phosphorous acid. Before or during the extrusion, A) 0.05 - 0.5% by weight of the phenolic stabiliser and B) 0.02 - 0.5% by weight of a phosph...
