Gama-Sperse® 80

Gama-Sperse® 80 by Imerys is a dry fine ground, white calcitic marble (untreated calcium carbonate). It provides improved rheological, mechanical, dispersion and optical properties. Gama-Sperse® 80 is used in rigid PVC compounds, polyefin compounds, calendered sheeting, PVC flexible footwear, profile extrusions and flexible applications. Its fine particle size and low 325 mesh offers good performance in applications where a high Hegman grind and a smooth surface are required.
