High-whiteness ground calcium carbonate (GCC) — coated and uncoated, ~1250 mesh — for masterbatch, film, and PVC. Kantor Materials produces it through a vertically integrated Vietnamese operation and supplies it alongside China-origin resin as a single sourcing relationship.
A premium grade where it counts — high whiteness and fine, consistent particle size for applications where domestic mid-grade powder underperforms or pushes up TiO₂ cost. Final spec is confirmed per lot against your application.
Whiteness sells the white-and-opaque segment (masterbatch, white film, caps, light PVC). It is not a substitute for TiO₂ — CaCO₃ extends titanium dioxide, it does not replace it. We will tell you where the grade earns its premium and where ordinary filler is the right call.
A converter importing resin from China and filler from Vietnam is running two certificate-of-origin regimes, two suppliers, and two FX exposures. We handle both — China-origin resin on Form E and premium Vietnamese GCC on its preferential certificate (Form D within ASEAN, Form AI into India) — as one quotation, one set of documents, and one point of accountability.
That puts one party accountable for getting both certificate regimes right, simplifies coordination, and gives you a single point of accountability for the quality of what arrives — while either input can still be sourced on its own.
The cleanest fit. High-whiteness fine powder for compounders making CaCO₃ masterbatch for sacks, film, and sheet.
Where whiteness, fine particle size, and coated dispersion matter most — thin gauges expose agglomeration and specks.
Pipe, profile, and fittings where a high-whiteness filler protects appearance at higher loadings.
Opaque-white bottles, caps, and closures — the segment where whiteness genuinely earns its premium.
A premium filler is only worth it if the second container matches the first. The grade is specified up front, with full lot documentation available on qualification.
Kantor-branded TDS covering whiteness, particle size, purity, oil absorption, and coating level.
Whiteness, D50, CaCO₃ content, residue, and moisture confirmed per production lot.
Form D or Form AI for Vietnam-origin GCC, and Form E for China-origin resin — preferential duty where it applies.
Third-party heavy-metals panels (Pb / As / Cd / Hg) available on request to support food-contact and premium qualification programs.
Send your application, target loading, and required fineness. We will respond with a matching grade, the documentation, and advice on running a one-lot line trial.
