Disclosed herein is a composition for suppressed die lip buildup. The composition may comprise from about 20 wt. % to about 98 wt. % of a polycarbonate; from about 0.01 wt. % to about 30 wt. % of a polybutylene terephthalate; from about 0.5 wt. % to about 60 wt. % of a functional filler; from about 0.1 wt. % to about 5 wt. % of an ultra-high molecular weight polydimethylsiloxane; and from about 0.01 wt. % to about 30 wt. % of a flame retardant component. The composition may exhibit a notched Izod impact strength of greater than 30 J/m when tested in accordance with ASTM D256 and may exhibit less die buildup during a continuous extrusion process when compared to a substantially similar reference composition in the absence of the ultra-high molecular weight polydimethylsiloxane.
