ABSTRACT:
Disclosed is a method for injection molding certain hydrodisintegratable materials which, when injection molded to form a desired object, acquire and maintain the desired shape. The method includes the steps of maintaining extrusion temperatures of the hydrodisintegratable material at or below about 250 degrees F. and maintaining the temperature of the mold at or below about 55 degrees F. In the presence of water, the molded object has the ability to rapidly disintegrate and disperse when subjected to standardized agitation testing.
