Luzenac R7

Luzenac R7 is high brightness, high purity, very platy, ultrafine talc with excellent top-size control that has been treated to provide improved scratch and mar resistance, dispersion, and color-matching along with excellent stiffness, HDT, dimensional stability, impact strength, and aesthetics in high performance plastics. It is compacted for maximum extruder throughput, minimum dust, and improved dispersion.

Luzenac R7 is used for reinforcement of plastics mainly in engineering thermoplastics where it significantly improves dispersion and impact resistance of the final compounds, and in polyolefin compounds (especially polypropylene and TPOs) where it improves scratch and mar resistance of talc-filled compounds without negatively impacting stiffness and other mechanical properties of the compound. The use of Luzenac R7 could also results in some improvements in brightness and thermal stability of plastic compounds.
