Process for the manufacture of an agglomerated abrasive material.

摘要

Agglomerated abrasive material suitable for use in liquid abrasive cleaning compositions comprises inorganic filler and a polymeric binding agent selected from polyalkylenes, copolymers of polyalkylenes with each other and copolymers of polyalkylenes with up to 30% by weight of monomers containing a carboxylic acid or ester group. These agglomerates can be prepared by a process in which a melt of inorganic filler in polymeric binding agent is formed and thereafter further inorganic filler is added to the melt to raise the weight ratio of inorganic filler to binding agent above a level at which the melt spontaneously crumbles.
