BMC 605 - SOLIAO

About
BMC 605 molding compound is a mineral filled, glass-fiber-reinforced polyester compound suitable for compression, transfer and stuffer injection molding. It is characterized by good moldability, medium impact strength, excellent overall electrical properties and flame resistance. Typical applications include circuit breakers, transformer bobbins and motor end bells. BMC 605 molding compound is produced in extruded form in a range of 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 extrusions and weight tolerances are plus or minus 5 %, up to a maximum of plus or minus 15 grams.&&
