Epgc203 Epoxy Glass Fabric Laminated Sheet(F Grade G11)

EPGC203 (equivalent to F Grade NEMA Grade G11 and DIN HGW 2372.4) is a premium industrial rigid laminate. It is engineered from alkali-free electronic glass cloth impregnated with a high-Tg (glass transition temperature) epoxy resin binder.

Unlike standard FR4 (EPGC202), EPGC203 is specifically designed to maintain at least 50% of its flexural strength at elevated temperatures (up to 150°C), making it the gold standard for thermal stability in rigorous environments.

Thickness: 0.3mm-50mm

Dimension:1020*1220mm 1220*2040mm 1220*2440mm

Thermal Class: F Class 155℃

Color:Light green

EPGC203 is designed for electrical insulation and structural applications requiring high mechanical strength, excellent dielectric properties, and superior heat resistance. Manufactured from woven fiberglass cloth impregnated with epoxy resin under high pressure and temperature, this material is widely used in motors, transformers, generators, switchgear, and industrial equipment.
