ABSTRACT:
The use of comminuted, recycled glass powders as a filler in molded plastic parts is disclosed. The recycled glass preferably has rounded edges, which is a distinct advantage over conventional ground glass which has extremely sharp edges. Suitable comminuted glass is free from contaminants such as grinding compounds. The comminuted recycled glass filler can be used with a variety of different thermoplastics commonly used to in injection molding, rotational molding, and blow molding of plastic parts.
