FAQ

1. What is G10 Rod (EPGC41)?

G10 Rod (EPGC41) is a high-performance insulating material made from woven glass fiber cloth impregnated with epoxy resin and laminated under high temperature and pressure. Compliant with NEMA G10 standards, it offers exceptional mechanical strength, high-temperature resistance, and electrical insulation, widely used in electronics, aerospace, and industrial equipment.

2. Key Properties of G10 Rod?

Insulation: Dielectric strength ≥40kV/mm .

Temperature Resistance: -50°C to +130℃.

Chemical Resistance: Resists acids, alkalis, and organic solvents (except strong oxidizing acids).

3. Typical Applications?

Electrical Insulation: High-voltage switchgear, transformer spacers.

Structural Support: Drone frames, robotic joint bushings, precision instrument brackets.

Harsh Environments: Radiation-resistant parts in nuclear plants, moisture-proof marine components.
