Abstract
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.
