Abstract
The invention provides a flame retardant polyolefin composition comprising a) an ethylene based plastomer with a density in the range of 0.850 to 0.915 g/cm3 and an MFR2 in the range 0.5-30 g/10 min; b) a propylene based plastomer with a density in the range of 0.860 to 0.910 g/cm3 and an MFR2 in the range 0.01-30 g/10 min; and c) a flame retardant.
Claims16
