Pme Asia Group supplies natural wollastonite powder, a calcium silicate mineral with the formula CaSiO₃. The product appears as a white crystalline powder with a pearl‑like luster, and typical whiteness levels range from 90 % to 94 %. Its bulk density lies between 2.87 and 3.09 g cm⁻³, while the Mohs hardness is reported between 4.5 and 6.0. The mineral melts at a typical temperature of 1540 °C and exhibits low heat swelling and low loss on ignition.
Standard particle morphology is needle‑like, which provides reinforcement benefits in composites. Typical moisture absorption for wollastonite is low, often below 0.2 % by weight, making it suitable for moisture‑sensitive applications. The powder’s silica (SiO₂) content falls between 48 % and 51 %, and calcium oxide (CaO) around 47 %, with minor aluminium oxide present. These composition ranges align with industry specifications for high‑purity filler grades.
The material is widely used as a filler in ceramics, as a reinforcement in plastics, as a brightening agent in paints and as a flux in metallurgy. Pme Asia Group ships the powder from Kolkata, West Bengal in 1‑tonne jumbo bags or bulk bags, ready for large‑scale industrial consumption. Prospective buyers should ask the supplier to confirm the exact batch analysis, any required certifications such as ISO 9001, and the anticipated delivery schedule.

Importers should obtain a recent batch analysis report and any applicable quality certificates, such as ISO 9001 or SGS test results, to confirm the chemical composition and whiteness claims. Request a sample of the powder to assess particle morphology and moisture content before finalising the purchase. Verify the supplier’s export licence and confirm the minimum order quantity and lead‑time for the chosen packaging format.
Shipping from Kolkata generally uses container freight, with the powder loaded into sealed jumbo bags placed on pallets. Buyers need to agree on the Incoterm, commonly FOB Kolkata Port or CIF a destination port, and clarify whether the bags will be shipped pre‑sealed or require on‑site repacking. Freight costs should be calculated using the bulk density and bag weight provided by the supplier.
A pre‑shipment inspection by an independent laboratory can verify the reported SiO₂, CaO and whiteness levels, as well as moisture content. Upon arrival, perform a visual check for bag integrity and conduct a quick moisture test to ensure the low absorption claim holds. Retain all inspection certificates and ensure the purchase contract includes clear terms for returns or non‑conforming batches.
