Abstract
A composition comprising (A) at least one bisphenol-A polycarbonate resin, (B) at least one polypropylene, preferably a high crystallinity polypropylene, (C) at least one compatibilizer comprising an amine functionalized elastomeric polymer, (D) at least one organic phosphate flame retardant, preferably an organic phosphate that is liquid at room temperature, and, optionally, (E) one or more additives. These compositions are useful in the manufacture of wire insulation coatings of less than 0.2 mm with good scrape abrasion resistance.
