| BMC 1901 molding compound is a mineral filled, glass-fiber-reinforced alkyd compound suitable for compression transfer molding. It is a general purpose with medium impact strength and good overall electrical properties. Typical applications include switch components, relay bases, stack insulator s and as a formable insulating putty for motor construction and repair. BMC 1901 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 weigh, in diameters from 3/4" to 2 7/8". 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. This product is also available in the form of continuous, Round rope in diameters ranging from ¾" to 1 ¼". Diameters of ½" and 5/8", as well as selected flat rope shapes, are supplied at an additional charge. |
