Abstract

Cellular polymeric material in the form of separate and/or interconnected filaments and/or strands may be further expanded by heating to a temperature which is above 85 DEG C. but below the softening temperature of the polymeric material. The polymeric material contains a vaporizable expanding agent, absorbed in some way, which will be released into the cell spaces at temperatures above 85 DEG C. Suitable polymeric material is polystyrene or a styrene interpolymer containing at least 50% by weight of styrene and the heating of the material may be by direct contact with a liquid or vapour having no solvent action on the polymer, e.g. water or steam. The filaments and/or strands may be crushed before the further expansion to provide a finished product which has a finer cell structure and is more flexible. Articles may be produced from the filaments and/or strands either alone or in a combination with cellular or non-cellular materials, by direct bonding. Suggested articles are bottle sleeves, decorative tiles, building panels and packaging materials.
