PHENOLIC PAPER SHEETS
Product Description
Phenolic Paper Sheets & Rods are cost-effective, rigid, and electrically insulating thermoset laminates produced by impregnating high-quality cellulose paper with phenolic resin under heat and pressure.
The result is a strong, lightweight, and machinable material that offers:
- Excellent electrical insulation for low & medium voltage applications
- Moderate mechanical strength for structural and support components
- Cost-effectiveness compared to fabric or glass laminates
They are widely used in switchgear, transformers, control panels, and general insulation applications where cost and electrical performance are critical.
Main Benefits
- Excellent electrical insulation properties
- Lightweight yet rigid material
- More economical than fabric/glass laminates
- Good machinability (cutting, drilling, turning)
- Moderate mechanical strength (sufficient for insulation & support)
- Stable dimensions under normal load
- Heat resistance: continuous up to 105–120°C
- Resistant to oils, waxes, and many solvents
