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. BMC 610 molding compound is produced in extruded form in a range on industrial colors. It is available in logs up to 12 inches in length or as precut slugs, of specific weight, in diameters 1” to 2 ½” . Within this range, smaller diameters are supplied as multiple extrusion and weight tolerances are plus or minus 5 %, up to a maximum of plus or minus 15 grams.Information provided by Bulk Molding Compounds
