Industrial Minerals
Paper & Board
Fillers and coating pigments for brightness, opacity and a printable surface.
The problem
Fillers and coating pigments decide brightness, opacity and printability — and they are also the cheapest tonne on the machine. The constraint is that nothing can disturb retention, drainage or the size press.
What we supply
Water-washed kaolin for coating and filler duty, GCC for alkaline furnishes, and talc where pitch control is the real problem rather than optics.
Choosing a grade
| What you are solving | What we would quote | Why |
|---|---|---|
| Coating, gloss grades | Kaolin XK-Coating | Fine plates, controlled rheology |
| Filler, wood-free | Kaolin XK-Filler | Brightness at low cost |
| Alkaline furnish filler | Calcite XC-1500 | High brightness, needs alkaline pH |
| Pitch and stickies control | Talc XT-500 | Hydrophobic surface adsorbs tacky material |
| Opacity without TiO₂ | Calcined kaolin | Light scattering from the fired structure |
These are starting points, not prescriptions. Send your current material's data sheet and we will match it properly rather than guessing from a mesh number.
Minerals for paper & board
3 of the minerals we supply end up in this industry. Here is what each one is actually doing once it is in the mix.
- China Clay (Kaolin) — Filler and coating pigment; the single largest use worldwide.
- Talc — Filler and pitch-control agent; improves smoothness and ink receptivity.
- Calcite / Ground Calcium Carbonate — Filler and coating pigment in alkaline papermaking.
China Clay (Kaolin)
Fine white aluminium silicate. Brightness and coverage in paper, paint and ceramics.
Talc
Soft, platy magnesium silicate. The workhorse extender in paint, plastics, paper and rubber.
Calcite / Ground Calcium Carbonate
High-brightness GCC. The cheapest way to add volume without losing whiteness.
Every one of these has its own page with the grade ladder, the typical chemistry and the physical properties. If you already know the mineral and need the numbers, go straight there.
What we will ask you
- Machine type and furnish
- Current filler and loading
- Brightness target
- Monthly tonnage and delivery ZIP
Four answers are enough for a quote and a sample. We do not need a meeting first.
What you get back
- A delivered price per tonne or per pound to your ZIP code, not an FOB India number you have to convert
- A free sample of the grade we recommend, shipped from the United States
- The typical analysis and, with the sample, the actual mill test certificate for that lot
- A safety data sheet in US format before the material arrives
- A lead time you can plan a production run around
