Polyethylene Glycol Ceramic Plasticizer & Binder
CAS Number: 25322-68-3
Polyethylene glycol (PEG) is a versatile water-soluble polymer used as a plasticizer, binder, and lubricant in ceramic forming processes including dry pressing, extrusion, and spray drying. PEG grades 1000–6000 are most common for ceramics, providing excellent lubrication during compaction and clean, low-residue burnout during binder removal.
Technical Specifications
| appearance | White waxy solid or viscous liquid depending on MW |
| purity (%) | ≥99 |
| moisture (%) | ≤0.5 |
| molecular weight range | 1000–6000 g/mol (standard ceramic grades) |
| hydroxyl value (mg KOH/g) | 18–112 |
Applications
- Plasticizer and lubricant in ceramic dry pressing
- Spray-drying aid to improve granule flowability
- Binder in ceramic tape casting formulations
- Pressing lubricant for advanced technical ceramics
- Carrier in wax-based injection molding systems
Key Features
- Excellent lubrication reduces pressing forces and die wear
- Clean burnout below 450 °C with very low ash residue
- Water soluble for easy aqueous binder preparation
- Wide MW range allows fine-tuning of viscosity and burnout profile
