Industrial & Food Grade
The table below compares our two talc grades: MICROFIL, our general-purpose grade, and TALC IP, a food-grade talc. Use particle size (D50) and topcut (D98) to gauge fineness and consistency, and brightness (Ry) to match your whiteness requirement.
| Grade | D50, microns | Topcut (D98) | Brightness (Ry) | Applications | Stocked In |
|---|---|---|---|---|---|
| MICROFIL | 5 | 20 | 94 | Paint & Coatings Paper Rubber & Plastics Ceramics | DBN & CPT |
| TALC IP (Food Grade) | 5 | 90 | 94 | Food grade | DBN & CPT |

As the softest mineral (Mohs hardness 1), talc offers natural lubricity and water-repellent behaviour, valuable in plastics processing (reduced friction, improved flow), cosmetics and waterproofing compounds.
Talc's flat, lamellar particles improve reinforcement and barrier properties in plastics and rubber, and support matting/sheen control in paint.
Supports appearance and opacity requirements in paint and paper applications.
Low reactivity makes talc stable across formulations, a key reason the TALC IP grade qualifies for food-grade use.
