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.

Flame retardant thermoplastic composition of polycarbonate and polypropylene

The present disclosure is directed to a halogen-free composition and conductors coated with the halogen-free composition. The halogen-free composition includes (A) from 70 wt % to 85 wt % of a polymeric component and (B) from 30 wt % to 15 wt % of a halogen-free flame retardant. The polymeric component (A) includes (i) a propylene homopolymer or a mini-random copolymer with greater than 40% crystallinity and (ii) an ethylene/a-olefin copolymer. The halogen-free composition has a density less than 1.15 g/cc. The halogen-free composition also has a scrape abrasion resistance of greater than or equal to 350 cycles as measured in accordance with ISO 6722.

Halogen-free propylene-based insulation and conductor coated with same

The present disclosure is directed to a plasticizer, polymeric compositions containing the plasticizer, and conductors coated with the polymeric composition. The plasticizer includes (i) an epoxidized fatty acid methyl ester, (ii) an epoxidized natural oil, and (iii) an epoxidized tallate ester. Polymeric compositions containing a polymeric resin and the plasticizer exhibit a weight loss less than 50 mg/cmafter exposure to 100&#xb0; C. for seven days. Conductors coated with the polymeric composition (containing the plasticizer) pass the low temperature unwind test of UL719 and exhibit a weight loss less than 50 mg/cmafter exposure to 100&#xb0; C. for seven days.
