Product Description
3240 Epoxy Phenolic Glass Fabric Laminated Sheet
Description
Epoxy phenolic glass cloth laminated sheet is made of alkali-free E-glass cloth
impregnated with epoxy resins and phenolic resins by processing under heat and pressure.
This product having high mechanical and dielectric properties, fine heat and humidity resistance,
can be used in electrical machine and devices as insulating construction parts in moist circumstances and in transformer oil
