| BMC 620M molding compound is a mineral filled, glass-fiber-reinforced polyester compound suitable for compression, and stuffer injection mo lding It is characterized by high impact strength, good moldability, excellent overall electrical properties and flame resistance. Typical applications include phase separators circuit breaker housings, and applications requiring the properties of Military specification Mil-M-14G Type MAI-60. Although BMC 620M was designed to meet this specification, it has not been submitted for QPL recognition. BMC 620M molding compound is produced in a range of industrial colors, and is supplied in bulk form only. |
