Material Notes:
BMC 501 molding compound is a mineral filled glass-fiber-reinforced compound suitable for compression, transfer and stuffer injection molding. It provides the user with good electrical properties And extremely low water absorption. This product has a low mold shrinkage and resists the formation of internal voids normally associated with glass filled compounds.Typical applications include slip rings, brush holders and connector bases.
