  • Thermoplastic polyolefin compounds with decreased flaming sensitivity
    Patent number: 8846805
    Abstract: Thermoplastic polyolefin compounds for the production of injection molded, paintable and flame pre-treatable articles comprising A) 50 wt % to 90 wt % of a propylene homo- or copolymer matrix phase (M) and B) 10 wt % to 50 wt % of a first elastomer comprising an ethylene-C3-C6-alpha olefin copolymer rubber C) 0 wt % to 20 wt %, based on the total weight of A and B, of a second elastomer, component B) and C) forming a disperse phase (E) and D) >30 wt % up to 60 wt %, based on the total weight of components A, B and C, of an inorganic filler, if the intrinsic viscosity of the disperse phase (E) is <2.2 dl/g according to ISO 1628 (with decalin as solvent) or 0 wt % to <30 wt % based on the total weight of components A, B and C, of an inorganic filler, if the intrinsic viscosity of the disperse phase (E) is ?2.2 dl/g according to ISO 1628 (with decalin as solvent).
