Talc Powder for Plastics
Filler and functional additive for PP, PE, EVA and masterbatch — ground in our own plant from the Haicheng talc belt, 325–3000 mesh, COA with every batch.
Why plastics compounders use talc
Stiffness and heat resistance
Talc's platelet particles reinforce the polymer matrix: in PP and other polyolefins they raise flexural modulus and heat deflection temperature, so parts keep their shape at use temperature.
Dimensional stability
Filled compounds shrink and warp less, so moulded parts hold tolerance better — what matters for large-area panels and thin-wall packaging.
Anti-blocking for films
Fine talc keeps PE and PP film layers separable in the roll without relying on heavy slip dosing.
Low abrasion
Talc is the softest industrial mineral on the Mohs scale, so it is gentle on screws, dies and calender rolls even at high loading ratios.
Grades for plastic compounds
| Grade | Mesh size | Purity | Whiteness | Moisture |
|---|---|---|---|---|
| Talc Powder 325 Mesh | 325 | 15-60 | 75-94 | ≤0.5 |
| Talc Powder 600 Mesh | 600 | 15-61 | 75-93 | ≤0.5 |
| Talc Powder 800 Mesh | 800 | 15-60 | 75-94 | ≤0.5 |
| Talc Powder 1250 Mesh | 1250 | 30 | ≥ 93 | ≤ 0.5 |
| Talc Powder 2000 Mesh | 2000 | 15-61 | 75-93 | ≤0.5 |
| Talc Powder 3000 Mesh | 3000 | 40 | 93 | ≤ 0.3% |
Values are typical production ranges per grade. Final values follow your confirmed specification, with a COA issued for every batch. Custom targets on request.
Matching the grade to the application
| Application | Grade direction |
|---|---|
| PP compounds & automotive interior parts | 1250 mesh and finer — surface finish and stiffness at moderate loading; finer grades raise modulus but cost more per tonne. |
| EVA foaming | Fine, high-whiteness grades disperse evenly into the foam and support a more uniform cell structure. |
| PE / PP film anti-blocking | 1250–3000 mesh — the finer the grade, the lower the dosing needed for the same anti-block effect. |
| Masterbatch carrier systems | High-whiteness fine grades for clean colour and stable dispersion through the masterbatch. |

Frequently Asked Questions
Why do PP compounders choose talc over other mineral fillers?
Talc combines reinforcement with low abrasion. Its platelet particle shape raises flexural modulus and heat deflection temperature in polypropylene, while its Mohs-1 softness keeps wear on screws and dies low even at high loading ratios. That combination of stiffening effect and gentle machine wear is hard to replace.
Which talc fineness suits my plastic application?
As a starting point: 325–800 mesh for cost-driven structural and moulded parts where high loading matters most; 1250 mesh and finer for automotive interior parts, appliances, films and masterbatch, where surface finish and dispersion matter. Send us your polymer and target loading ratio and we will propose 2–3 candidate grades with samples.
What documentation comes with each shipment?
Every order ships with a certificate of analysis covering the indicators agreed in the contract, and third-party inspection can be arranged before shipment on request. The ranges in the table above are typical production ranges; final values follow your confirmed specification. Samples are free, with courier cost on the buyer.
