Detailed Product Description

To manufacture such materials modified polystyrene or other thermoplastic material (polyvinyl acetate, etc.) can be used. Modified polymer is mixed with low boiling substance (isopentane or its fraction), is poured into a hollow autoclave and heated to 180 o C. Then the pressure is released and the foaming polymer fills completely the hollow autoclave of the set shape. In certain time, depending on the modified polymer, the autoclave must be opened and porous polymer is taken out. Thermal and sound insulating materials will have higher mechanical strength than polysterene manufactured in usual method, as foaming material will have cross closs-links between polymer chains formed by oligomer oxide materials.
