Patent ID: 8846805

Claim:
Thermoplastic polyolefin compounds for the production of injection moulded, paintable and flame pre-treatable articles comprising A) 50 wt % to 90 wt %, based on the total amount of thermoplastic polyolefins, of a propylene homo- or copolymer matrix phase (M), and B) 10 wt % to 50 wt %, based on the total amount of thermoplastic polyolefins, of a first elastomer comprising an ethylene-C 3 -C 8 -alpha olefin copolymer rubber, C) 2 wt % to 10 wt %, based on the total weight of A and B, of a second elastomer, which is an ethylene-1-octene copolymer rubber, component B) and C) forming a disperse phase (E) with an intrinsic viscosity of ≧2.2 dl/g according to ISO 1628 (with decalin as solvent), and D) 10 wt % to 30 wt % based on the total weight of components A, B and C of an inorganic filler which in combination with the intrinsic viscosity is effective for increased thermal conductivity effective to provide decreased flaming sensitivity or no flaming sensitivity during flame pre-treatment of the article prior to painting, wherein a MFR 2 of the matrix phase (M) is 40 to 200 g/10 min (measured under a load of 2.16 kg at 230° C. according to ISO 1133), wherein the component C) is different from component B).
