Import Calcium Carbonate Powder — Buy in Bulk from Supplier in Viet Nam

Caco3-YBC Vietnam Joint Stock Co. supplies calcium carbonate powder with a stated purity level exceeding 98%, making it suitable for industrial applications where consistency is critical. The product is characterised by low impurity content, with magnesium oxide (MgO) below 0.4%, silica (SiO2) below 0.2%, and iron oxide (Fe2O3) below 0.1%, which minimises discolouration or chemical interference in end products. The fine particle size is engineered for uniform dispersion in matrices like plastics, rubber, and coatings.

This grade of calcium carbonate is classified as GCC (ground calcium carbonate), typically produced from high-purity limestone through mechanical grinding and classification. Standard industry specifications for such grades include a top cut of 45 microns or finer, with a d50 (median particle size) around 5 microns for optimal performance in fillers and extenders. The material’s low oil absorption, often below 15 g/100g, ensures minimal impact on the rheology of liquid systems, while its high brightness (typically ≥ 92) enhances the visual appeal of coated papers and paints.

Primary buyers include manufacturers of PVC profiles, masterbatches, and adhesive formulations, where the powder serves as a reinforcing filler to improve stiffness and impact resistance. For bulk orders, the material is supplied in 1-tonne jumbo bags or 50 kg sacks, with optional coating agents like stearic acid to enhance compatibility with hydrophobic polymers. Buyers should confirm the coating type and loading, as well as the supplier’s ability to meet specific sieve residue or surface treatment requirements.

Caco3-YBC Vietnam Joint Stock Co. is headquartered in Hanoi, with its address at 1-N8B, Nguyen Thi Thap Street, Nhan Chinh Ward, Thanh Xuan District. The company operates as an imported-tier supplier, indicating it engages in cross-border trade of mineral additives, likely sourcing raw materials from international markets for processing or redistribution. Its harbor trust tier suggests a verified business presence but does not imply production or certification details beyond basic legitimacy.

The supplier’s profile currently shows a response rate of 0.00 and no recorded average response time, which may indicate limited engagement or operational delays. The listing does not disclose manufacturing capacity, quality management systems, or third-party certifications like ISO or SGS, so buyers are advised to request these documents directly to assess compliance with their technical and regulatory requirements.
