| BMC 2201 molding compound is a mineral filled, glass-fiber-and nylon-floc reinforced alkyd compound suitable for compression and transfer molding. It was developed for applications requiring better abrasion resistance than that available with other BMC products. BMC 2201 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 from ¾ ” 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 of plus 15 grams.&& |
