Thickness: 0.3mm-80mm
Length: 1020*2020mm
Color:Yellow(other colors can be customized)
3240 Epoxy fiber glass cloth laminated sheet (grade A): dip alkali-free glass fiber cloth in epoxy phenolic resin, then bake and heat press. It has good mechanical and dielectric properties with thermostability and moisture resistivity and good machinability. The thermostability grade is B.It is widely used in generator,motor,electronic apparatus as insulating material and components. It is also suitable under oil pressure of transformer and wet environment.
