Uncoated Precipitated calcium carbonate

Light calcium carbonate, also known as precipitated calcium carbonate, has active light calcium carbonate and ordinary light calcium carbonate. It is commonly used as a filler and is widely used in daily chemical industries such as artificial floor tiles, rubber, plastics, papermaking, coatings, paints, inks, cables, building supplies, food, medicine, textiles, feed, dental paste, etc. As a filler, it increases the volume of products and reduces production costs.

Product Overview

YINGFENG is a micro-scale uncoated precipitated calcium carbonate according to norm ISO 3262 part 6. uncoated precipitated calcium carbonate is a white and odorless powder prepared by calcium carbonate precipitation, dehydration, drying and crushing. It could be in the form of slurry. YINGFENG micro-scale uncoated precipitated calcium carbonate exhibits specific topography, high whiteness, purity, and dispersity. High retention, brightness, opacity, strength, and bulk et al. Could be obtained when paper was filled or coated with YINGFENG micro-scale uncoated precipitated calcium carbonate. YINGFENG micro grade uncoated precipitated calcium carbonate is most commonly used in paint, rubber, and plastics et al. As an extender for titanium dioxide. uncoated precipitated calcium carbonate can provide functionalities, increasing the performance of the resin, adding thickening, unsinkability, impact strength, flexural modulus (stiffness), dimensional stability, and surface finish. This minerals is also used as cost-reducing fillers by extending or replacing the more expensive resins.
