Coated vs Uncoated Calcium Carbonate
Coating is a surface treatment — most commonly stearic acid or a stearate — applied to CaCO₃ particles to make them hydrophobic and more compatible with non-polar polymer melts. Coated grades disperse more easily, reduce moisture pick-up during storage and…
ReadCalcium Carbonate in Plastics
Calcium carbonate is used in plastics for three distinct reasons, often at the same time: cost reduction by displacing more expensive polymer with a cheaper mineral; process function — modifying rheology, thermal behaviour, dimensional stability and…
ReadGCC vs PCC — Ground vs Precipitated Calcium Carbonate
GCC (Ground Calcium Carbonate) is produced by mechanically grinding natural limestone, marble or chalk. PCC (Precipitated Calcium Carbonate) is synthesised by carbonating a calcium hydroxide slurry with CO₂ under controlled conditions. The two share the…
ReadCalcium Carbonate (Raw Powder) — Industrial Uses, Applications and Buying Guide
Calcium Carbonate (Raw Powder) (CaCO₃ — GCC (ground) or PCC (precipitated)) is a bulk industrial raw material used across multiple manufacturing sectors. This page explains it as part of an ecosystem — how it fits into products, processes, and Allzone's…

- Anti-static Masterbatch — Static Electricity on Plastic Film or PartsPlastic parts or film hold a static charge — attracting dust, sticking, or creating ESD risk in electronics packaging.
- Desiccant Masterbatch — Bubbles, Streaks, or Splay When Processing Regrind or Wet ResinRegrind or hygroscopic-contaminated resin produces bubbles, silver streaks, or splay marks in the finished part, and drying is not practical or sufficient.
