Kind Code:
B2
Abstract:
A method of preparing a polystyrenic foam having improved uniformity of properties across its cross-section involves passing the foam immediately after its extrusion through a molding (or shaping) device which is heated or maintained at an elevated temperature rather than being cooled or uninsulated. It is further preferred to post-expand the resultant foam in hot air.
