    Product Description

    This product is made with the electrician non-alkali glass fiber cloth as the backing material, with high TG phosphorous and nitrogen flame retardant epoxy resin as binder via hot pressing laminated products, high mechanical strength and low combustion performance under normal temperature, high temperature under 155 ℃ still has strong mechanical strength, good electrical properties under dry and wet state, can be used in damp environment and transformer oil,It is a class F heat-resistant insulating material.Applicable to all kinds of motor, electrical, electronic and other fields, widely used in motor, electrical equipment as insulation structure parts, high voltage switch-gear, high voltage switch (such as motor stator insulation materials at both ends, rotor end plate rotor insulation piece, slot wedge, terminal board, etc.).


    1.Good electrical stability under high humidity;
    2.High mechanical strength under high temperature;
    3.Moisture resistance;
    4.Heat resistance;
    5.Temperature resistance:Grade F
    6.Halogen-free and fire retardant


    Compliance with standards
