ABSTRACT:
Silicate filled polyolefin resin composites exhibit improved mechanical properties if the silicate filler and polyolefin resin are specially combined with additives comprising chlorinated aliphatic compounds. The composites are preferably made from blends comprising about 1-36 parts by weight silicate flakes or fibers, 9 parts by weight propylene resin and minor effective amounts of the additive. Various processing techniques such as selecting the time the blends reside at melt temperatures during compounding permits development of advantageous properties.
