Abstract
PURPOSE: To provide the title foam consisting of non-colored, high foaming, even and fine foam by heating and blowing after adding hexamine to the foaming composition containing azodicarbonamide as foaming agent and introducing a bridge formation.
CONSTITUTION: To heat and blow the foaming resin molding, which is a mixture of azodicarbonamide as foaming agent 0.5W50 by weight of polyolefin resin 100 parts by weight and of hexamethylenetetramine (hexamine) 0.5W50 parts by weight of azodicarbonamide 100 parts by weight, after, or while introducing bridge formation. By using hexamine in the most possible minute state, the mulling property with resin will improve so as to provide the envenly whitened foam.
