Buyer intent coverage
Calcium carbonate filler — what it is, where it is used, how it is chosen
Calcium carbonate is the highest-volume mineral filler in plastics, coatings, adhesives and construction products, used both to replace polymer volume and to modify stiffness, surface and thermal behaviour. Ground and precipitated grades behave differently, and stearate coating changes how well the mineral disperses in a non-polar polymer. Buyers should specify particle size, top cut and coating status, because those three variables control almost everything the filler does in a compound.
Primary uses
- Replacing polymer volume to reduce compound cost
- Increasing stiffness and dimensional stability
- Improving surface finish and printability
- Extending coatings, adhesives and sealant formulations
Applications
- Filled polyolefin compounds and filler masterbatch
- Rigid vinyl pipe, profile and sheet
- Paints, coatings, adhesives and sealants
- Construction products and building materials
Advantages
- Lowest-cost route to volume replacement in most polymer compounds
- Improves stiffness and can shorten cooling time in thick sections
- Coated grades disperse well in polyolefins without a separate coupling step
Limitations to consider
- Impact strength and elongation fall as loading increases
- Abrasive at high loading, increasing wear on processing equipment
- Acid-sensitive, which limits use in acidic systems
- Addition rate and performance are established on your own line; the figures quoted in supplier literature are starting points, not a specification.
How to choose the right grade
- Describe the machine, the polymer being run and the problem you are trying to remove
- State the maximum temperature the consumable has to work at
- Confirm whether the finished part has a food-contact, medical or other regulated requirement
- Confirm the physical form your equipment or operators can apply safely
- Check compatibility with the next material or coating that touches the part surface
- Exact specification is confirmed against supplier documentation at quotation.
Typical grades
- Ground uncoated grade
- Ground stearate-coated grade
- Precipitated grade
- Fine particle size grade
- Food-contact grade where the application requires it
- Reference grade names are widely used as shorthand in enquiries. They are treated here as search language only: an equivalent is confirmed by comparing declared datasheet values and by a line trial, and no grade is presented as a drop-in replacement for another.
Comparable materials — how Calcium carbonate filler sits against alternatives
- Talc where stiffness and heat resistance dominate
- Filler masterbatch where powder handling is impractical
- Kaolin or barium sulphate in specific coating systems
- Buyers searching for an alternative or second-source supplier should state the incumbent grade and the property they are matching, because a like-for-like comparison depends on the declared datasheet values and on line trials, not on the material name alone.
Comparable-material reference. Grade selection is confirmed at RFQ against your process.
Procurement coverage
How to specify, order and receive Calcium carbonate filler
Written for procurement, quality and technical buyers in Canada and the United States. No numeric price, MOQ, stock or lead-time value is published — those are confirmed per shipment in the quotation and against the confirmed batch.
How buyers specify at RFQ
- Machine type, size and the process being run
- Polymers involved before and after the operation
- Maximum processing temperature the consumable must withstand
- Regulatory status required for the finished part
- Physical form the operation can apply
- Downstream operations such as printing, painting or bonding
Packaging options (industry-standard)
- 25 kg bag or box — the usual format for dosing-unit refills
- Jumbo / FIBC bag for continuous gravimetric feeding on high-output lines
- Moisture-barrier or foil-lined packaging for hygroscopic and oxidation-sensitive actives
- Packaging options and available pack sizes are confirmed with each quotation.
Storage & handling
- Store cool, dry and sealed; heat and humidity degrade both carrier and active
- Keep concentrates in closed containers to avoid contamination of natural or light-colour runs
- Use first-in, first-out rotation and respect any retest or shelf-life date on the batch
Documentation available
- Technical data sheet (TDS) stating the active chemistry, carrier and recommended addition range
- Safety data sheet (SDS) in the format required for Canadian import
- Certificate of analysis (COA) against the confirmed batch
- Food-contact or regulatory declaration where the converted part requires it
- Documentation is confirmed per batch at quotation; availability depends on the grade and supplier offered.

Technical & procurement detail
Coated vs uncoated calcium carbonate — which one for your line?+
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.
CaCO3 masterbatch vs raw powder for plastic converters+
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 sources raffia-grade (PE carrier, MFI 4–6) and injection-grade (PP carrier, MFI 8–12) via our Ontario logistics partner.
Logistics from Toronto across Canada+
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-Ontario logistics partner. 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.
Frequently asked questions
What is the minimum order for calcium carbonate in Toronto?+
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.
Do you carry food-grade calcium carbonate?+
Yes — our PCC 0.8 µm grade carries a food-contact and pharma-grade COA. Documentation is provided per shipment.
Can you match a specific CaCO3 masterbatch specification?+
Yes. Send us your current TDS or a 2 kg sample and our supplier lab network can match MFI, ash, moisture and dispersion on a custom carrier (PE, PP, PS, PA, PET).
How fast can you deliver across the GTA?+
Regional GTA movements run on Ontario LTL carriers, and larger volumes move on dedicated trailers or direct from container. Actual transit time depends on the grade, the quantity and the delivery address, so it is confirmed with each quotation.
