G11 Epoxy Fiberglass laminate Sheet is created by compressing fiberglass cloth, soaked in high temperature resistant epoxy resin under heat with excellent mechanical and dielectric properties, good mechanical performance at high temperature and high humidity condition, and good processability.
1. High Heat Resistance (High Tg)
G11 is considered an upgraded version of G10. Its higher glass transition temperature (Tg) allows the laminate to maintain excellent mechanical strength and flexural performance even at elevated temperatures, making it suitable for demanding electrical applications.
2. Excellent Electrical and Mechanical Performance
G11 provides superior dielectric properties in both dry and humid environments. It also features high compressive strength, tensile strength, and dimensional stability, ensuring reliable performance in critical insulation systems.
3. Chemical Resistance
The material demonstrates strong resistance to various solvents and acidic chemicals, allowing it to perform well in harsh industrial environments.
G11 epoxy fiberglass sheets are mainly used in the following industries:
Electric motors and generators:Motor slot wedges,Insulation spacers and pads
Transformer insulation systems:Insulation blocks,Insulation clamps
High-voltage electrical equipment:Switchgear insulation supports,Busbar support plates,Circuit breaker insulation barriers
Electronics and PCB manufacturing:PCB testing fixtures,Electronic equipment frames
Industrial machinery components:
Planetary gears,Mechanical support plates,Wear-resistant pads
Renewable energy equipment (solar, wind, and energy storage)
