摘要:
A thermoplastic molding composition suitable for the preparation of foam is disclosed. The composition comprises a thermoplastic resinous component and a foaming agent which includes A) (i) 0.01 to 4.8% alumina hydrate (aluminum hydroxide) in combination with (ii) 0.01 to 4.8% of an acidic additive or B) 0.01 to 4.8% of the reaction product of said (i) and said (ii), the percentages being relative to the weight of the composition to be foamed. The invention is based on the finding that the foaming of the composition does not lead to any significant reduction in molecular weight of the resinous component or to troublesome discoloration of the foam, even during its re-extrusion.
