Reinforcing compositions for thermoplastic polymers, including a synergic combination of micronized silica and of calcium salt which have improved anticaking and flow properties

摘要

The invention relates to reinforcing compositions for thermoplastic polymers which have improved anticaking and flow properties, which include an impact additive and a synergic combination including a micronized silica and at least one calcium salt. These compositions are very particularly suitable for the reinforcement of PVC.
