Brief Introduction of the Epoxy Glass Cloth Board

Epoxy glass cloth laminated sheet is made of ethoxyline and glass cloth. It has high dielectric properties, tear strength and tensile strength, good impregnation performance.
It is characterized by excellent mechanical and electrical insulating properties, which keeps even at higher temperatures.
characterized by resistance to tracking.
It is used in the production of components with good mechanical and electrical properties, for electrical equipment at higher temperatures or in humid environments, for stressed electrical insulating components, such as chassis, body equipment, housing parts of distribution boards, transformers, switchgears, electrical machines.

Main Features of the Epoxy Glass Cloth Board

Insulation class: F class (155 °C)
Color: Yellow,special colours can be provided on request.
The 3240 epoxy resin glass cloth laminated sheet has been approved by UL (NO.: E310670) ,ROHS and REACH test.
