Paper & Plastic Industry Overview
Calcium Carbonate and PCC are the most widely used functional fillers, enhancing brightness in paper and stiffness in plastics.
Products Used
Filler plastik dan coating kertas
Filler premium untuk kertas art-paper dan plastik high-grade
Role of Limestone / CaCO3 in Paper & Plastic Industry
In paper, CaCO3 provides superior opacity. In plastics (PVC, PP), it acts as an anti-blocking agent and structural reinforcer.
Technical Requirements
| Parameter | Value / Standard |
|---|---|
| Brightness | > 94% |
| Purity (CaCO3) | > 98.5% |
| Absorpsi Minyak | 18–22 g/100g |
| D50 Particle Size | 1.2–2.5 µm |
Process Integration
- 1
Mixing & Compounding
CaCO3 dicampur dengan resin polimer (untuk plastik) atau pulp (untuk kertas).
- 2
Extrusion/Sheeting
Campuran diproses melalui extruder atau mesin kertas Foudrinier.
- 3
Quality Inspection
Pengujian kekuatan tarik, brightness, dan opacity pada produk akhir.
Industry Pain Points
Brightness rendah membuat produk kertas terlihat kusam atau kuning
Kandungan abrasif tinggi merusak screw extruder plastik
Distribusi ukuran partikel tidak merata menyebabkan cacat permukaan (surface pinholes)
