Natural Calcium Carbonates have been essential components of PVC window profile, paneling and foam board formulations for decades. In particular, they increase the hardness and impact strength of end products. The higher hardness allows the wall thickness to be reduced and therefore saves material.
Niğtaş offers a wide range of standard and special calcium carbonate products with different particle sizes and whiteness values for profile, paneling and foam board applications. Our coated product range improves the strength properties of end products, regulates viscosity, and provides a brighter and smoother surface due to its excellent dispersion properties in PVC polymers. Our products are chemically very pure and white, which saves pigments and reduces costs.
Thanks to their uniform grain size distribution curves, superior dispersion capabilities, whiteness properties and coating technologies compatible with PVC polymers, our GLS series coated products developed for the profile industry offer advantages such as easy demolding, fringing prevention, high gloss and impact resistance in profile production.
