Allzone Trading is a Toronto-area distributor of ground calcium carbonate (GCC), precipitated calcium carbonate (PCC) and CaCO3 filler masterbatch for plastic converters across Ontario, Quebec and Western Canada. We carry coated (stearic-acid surface-treated) and uncoated grades from D50 1.5 µm down to fine 0.8 µm powders, plus ready-to-extrude PE/PP carrier masterbatch at 60–80% loading.
Whiteness ≥ 96, Brightness ≥ 94, +325 mesh ≤ 0.05%
Oil absorption 18–22 g/100g, moisture ≤ 0.3%
Specific surface area 8–11 m²/g — for PVC and rigid film
MFI 4–6, ash 73–77%, raffia / blown film
MFI 8–12, ash 78–82%, injection / woven sacks
Uncoated CaCO3 is the lowest cost per kilogram but tends to absorb moisture and lower MFI. Stearic-acid-coated grades cost roughly 8–12% more but disperse cleanly in PE and PP at letdown ratios above 30%, protect screw barrels from build-up and reduce die-lip drool on blown-film lines. For Canadian converters running winter-grade resin with high stiffness requirements, coated GCC at D50 1.5 µm is the standard recommendation.
Buying CaCO3 as a 75–80% loaded masterbatch eliminates dust on the shop floor, removes the need for a separate gravimetric feeder and gives consistent dispersion run to run. For Ontario converters running multiple SKUs per day, the small carrier cost is more than offset by lower scrap rates and operator safety. Allzone stocks raffia-grade (PE carrier, MFI 4–6) and injection-grade (PP carrier, MFI 8–12) in Richmond Hill.
Most GTA customers receive same-week LTL delivery on pallets of 1,000 kg FIBC. Quebec and Maritime customers ship in 24-ton FTL truckloads ex-Richmond Hill. Direct container drops to converters in Mississauga, Brampton, Vaughan, Concord, Markham and Woodbridge are scheduled weekly. Western Canada (Calgary, Edmonton, Vancouver) ships rail-intermodal in 20-ton FCL.
We sell from a single 25 kg bag up to a full 20-ton FCL container. For first-time orders we recommend a 1,000 kg FIBC trial.
Yes — our PCC 0.8 µm grade carries a food-contact and pharma-grade COA. Documentation is provided per shipment.
Yes. Send us your current TDS or a 2 kg sample and our lab in Richmond Hill can match MFI, ash, moisture and dispersion on a custom carrier (PE, PP, PS, PA, PET).
Orders confirmed before 11 am ship the same day with next-business-day delivery anywhere from Oshawa to Burlington.
