3241 Semiconductor Epoxy Glass Sheet High Performance Electrical Insulation Laminate Board

product details

Description

The 3241 Semiconductor Glass Cloth Board is a high-performance laminated material manufactured by hot pressing alkali-free glass cloth impregnated with carbon black epoxy-phenolic resin.

This material exhibits semiconductor properties, making it suitable as anti-corona insulation between large motor grooves. In addition, it can serve as a non-metallic, wear-resistant structural material in high-stress and high-temperature environments.

With excellent mechanical strength, thermal stability, and electrical insulation, the 3241 board is ideal for demanding applications in large motors and industrial electrical equipment, where durability and reliability are critical.
