Products Description
1. Product Definition and Technical Parameters
Cotton Phenolic Laminate is a hard insulating material made from cotton cloth impregnated with phenolic resin and laminated under high temperature and pressure. It has excellent mechanical strength, heat resistance, and electrical insulation properties.
Key Indicators:
Density: 1.3–1.45 g/cm³ (affects mechanical support)
Heat Resistance: Continuous operating temperature of 120°C (H-level insulation standard)
Dielectric Strength: ≥ 20 kV/mm (IEC 60243 standard)
| Performance Dimension | Technical Advantage Description | Data Source and Verification Method |
|---|---|---|
| Mechanical Strength | Bending strength ≥ 120MPa (ensuring long-term structural stability) | Measured data from a universal material testing machine (ASTM D790) |
| Arc Resistance | Arc resistance ≥ 180 seconds (better than the 120 seconds of ordinary laminates) | UL 746A certification report |
| Environmental Friendliness | Compliant with RoHS/REACH standards (halogen-free, heavy metal-free) | SGS hazardous substance detection report |
| Dimensional Stability | Coefficient of thermal expansion < 3×10⁻⁵/℃ (no deformation in high-temperature environments) | Test data from a thermomechanical analyzer (TMA) |
Material Types:
Ordinary Cotton Cloth Board (low cost, suitable for general insulation applications)
High-Strength Cotton Cloth Board (reinforced with glass fiber, impact resistance increased by 30%)
Thickness Specifications: 0.5 mm, 1.0 mm, 2.0 mm, 3.0 mm (customization available with ±0.05 mm tolerance)
Surface Treatment: Single-sided/double-sided frosting (enhanced adhesion), pre-impregnated with epoxy resin (improved moisture resistance)
