The present invention relates to thermoplastic resin compositions,
particularly polyolefines, polyvinylchloride and polyamide. The
thermoplastic resin compositions contain between 3 and 400% by weight of
filler based on the weight of the resin, said filler comprising talc and
microsilica where the weight ratio between talc and microsilica is between
15:1 and 1:15. The invention further relates to a method for the
production of thermoplastic resin compositions, and to a filler blend for
use in thermoplastic resins, said blend containing talc and microsilica in
a weight ratio between 15:1 and 1:15.
