Luzenac R7

Chemical Name: Talc
Chemical Family: Silicates

Luzenac R7 is a 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 esthetics in high-performance plastics. It is compacted for maximum extruder throughput, minimum dust, and improved dispersion.
