3240 Insulation Epoxy Glass Cloth Laminated Sheet
This Epoxy Board is formed through heat pressing after electric industry alkali glass cloth dips into the epoxy epoxy resin. It has high mechanic and dielectric performance, and applicable as insulation structural components for electromechanical/electrical equipment, as well as used under damp environmental conditions and transformer oil.
Laminated material in sheets, made from modified non-alkaline glass fabric as a frotifier material and epoxy resin as a binder. In addition to its good mechanical and electro insulating properties. The material is self-extinguishing, classified as inflammable.
China Epoxy glass cloth laminated sheet for magnetic conductivity, with high mechanical strength, heat-resistance, with good magnetic permeability.suitable for making magnetic slot and wedge for motors.
