BMC 605LS molding compound is a low-shrink, mineral filled, glass-fiber-reinforced polyester compound suitable for compression, transfer and stuffer injection molding It is characterized by good moldability, medium impact strength and excellent overall electrical properties and flame resistance. Typical applications include circuit breakers, transformer bobbins and motor end bells. BMC 605LS 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 dia meters from 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. |
