CALCIUM SULPHATE CAS-20™-4

1 of 1 products in this brand
CALCIUM SULPHATE CAS-20™-4 is an anhydrous calcium sulfate known for its exceptional whiteness and finely divided particulate nature. It is produced from high-purity gypsum rock through controlled calcination and precise grinding processes, which significantly diminish its moisture absorption tendencies. It finds application as a filler, allowing for high loadings while consistently delivering a remarkable blend of properties and a pleasing surface appearance.
