  • Publication number: 20090215949
    Abstract: Blends of polycarbonate (PC) with an impact modifier, such as a butadiene-styrene based polymer like acrylonitrile-butadiene-styrene (ABS) polymers or methacrylate-butadiene-styrene (MBS) polymers, having improved flame retardance are disclosed. From about 0.5% to about 3% by weight of a filler selected from the group consisting of a clay, talc, and aluminum oxide particles are added to the blend. The resulting flame retardant polymer composition has improved flame retardance with acceptable maintenance of mechanical and/or processing properties.
