Product Description:
The Epoxy Glass Laminated Sheet is a high-performance industrial
laminated sheet. It is manufactured by hot-pressing chemically
treated non-alkali glass fiber cloth impregnated with high-Tg epoxy
resin, making it a Class H heat-resistant insulating material. This
product features high mechanical strength at elevated temperatures
and stable electrical properties under high humidity conditions,
and is widely used in electrical, electronic, and mechanical fields
that demand high reliability.
Advantages:
- Excellent High-Temperature Resistance: Class H insulation, it maintains high mechanical strength at
elevated temperatures.
- High Mechanical Strength: The glass cloth substrate provides outstanding flexural and impact
strength, making it suitable for structural components.
- Stable Electrical Properties: It retains excellent insulation properties and low dielectric loss
even in high-humidity environments.
