Stearic acid coated · PVC extrusion grade
Activated Calcium Carbonate
Surface-treated calcium carbonate for high-load filling in rigid PVC. The stearic coating keeps it hydrophobic, so it disperses cleanly and does not choke the machine.
Typical values
| Particle size (D50) | 2.0 – 2.5 microns |
|---|---|
| Surface treatment | 1.0% – 1.2% stearic acid coating |
| Whiteness / brightness | 95% minimum |
| CaCO₃ content | 98.5% minimum |
| Moisture content | 0.15% maximum |
| Oil absorption | 16 – 18 ml / 100 g |
These are typical values from regular production, not a contractual specification. A Certificate of Analysis can be arranged on request — tell us at the enquiry stage. If you need a tighter window on any parameter, ask us before ordering and we will confirm what is achievable.
Supply & packing
| Minimum order | 1 tonne (20 bags × 50 kg) |
|---|---|
| Packing | 50 kg HDPE woven sacks, inner LDPE liner |
| Availability | Despatched direct from the plant |

Pricing is quoted against your monthly contracted tonnage and delivery location. Send us the grade and quantity and we will come back with a landed price.
Applications
Where it is used
PVC pipes & fittings
Takes maximum filler loading without losing tensile strength or spiking extruder torque.
uPVC profiles & conduits
Improves surface finish, gloss and impact resistance on extruded profiles.
Masterbatch compounding
A functional extender with dispersion good enough to run at high let-down ratios.
Cables & wire sheathing
Holds insulation properties and structural integrity in PVC sheathing.
On your floor
What it changes
- Cuts raw material cost per tonne by displacing virgin resin
- Reduces extruder screw and barrel wear
- Increases line output speed
- Hydrophobic coating prevents moisture pickup and machine choking
