ABSTRACT:
An extruded synthetic resin foam comprises a cell structure of substantially two different cell sizes, the smaller size being not more than about 0.25 mm while the other size is from about 0.4 to about 1 mm. The cells are dispersed in an island in the sea manner. A foam such as a styrenic foam is produced by forming a mixture of synthetic resin, a fine mineral powder having hydroxyl groups, and a cell controlling agent, incorporating a volatile foaming agent and extruding the mixture to form a foam. The powder has a particle size of not more than 100 nm and may be a silica having silanol groups.
