Product Description

Product Description

Product features: good flame retardancy, insulation and high electrical strength; low water absorption and moisture resistance, good dielectric resistance, good mechanical strength and processability. The appearance and color of the board are uniform.

Product use: used for insulating structural parts and padding insulation boards in various electronic and electrical equipment, various motor slot wedges, gaskets, outlet boards, various transformer support strips and pads; can be used in humid environments and transformer oil; can be processed into various large motors, electrical and electrical insulation structural parts.

Product material: made of good transformer paperboard as raw material, bonded and pressed with insulating glue,

Production process: The application of new processes and equipment avoids the problems of bubbles, delamination, embrittlement and other problems that may occur in laminates. The veneer made by steaming, peeling and drying is coated with special insulating glue and made by high temperature and high pressure.
