Material Notes:
BMC 610 molding compound is a mineral filled, glass fiber-reinforced polyester compound suitable for compression, transfer and stuffer injection molding. It is set a part form other medium impact electrical grade materials by its very high arc resistance and outstanding flame resistance in thin sections.Typical applications include transformer bobbins, terminal boards, arc chutes and contactors.
