Allzone supplies high-purity micronised talc (magnesium silicate) and talc masterbatch to polypropylene compounders, automotive part moulders and engineering-plastics formulators across Ontario, Quebec and Western Canada. We stock D50 grades from 2 µm to 10 µm, both untreated and surface-treated for improved dispersion.

Drop-in talc concentrate, MFI 6–10
Adding 20–40% micronised talc to homopolymer or copolymer PP dramatically increases flexural modulus, raises heat-deflection temperature and reduces moulded-part shrinkage. This is why nearly every automotive interior part in North America contains 10–25% talc-filled PP. Particle size (D50) and aspect ratio determine the stiffness-vs-impact balance.
Surface-treated talc disperses faster in PP and PE and reduces moisture pick-up, which matters for moulded parts that need consistent dimensional stability. Untreated talc is the cost-down choice for less demanding applications.
Several automotive Tier 1 and Tier 2 compounders in southern Ontario take talc by the FTL truckload weekly. We coordinate JIT delivery from Richmond Hill to plants in Tillsonburg, Concord, Bradford and Markham.
Typical loadings range from 10% (light interior trim) to 40% (bumpers, structural parts). Higher loadings increase stiffness but reduce impact strength.
