Patent ID: 8283399

Claim:
A filled, TPO composition having a total energy absorption during impact at −30° C. of at least 22 ft-lb-f, (29.83 N-m or J) as measured by an Instrumented Dart Impact Test ASTM D3763 at 6.7 meters/second and a peak tangent flexural modulus equal to or greater than (≧) 2100 MegaPascal (MPa) (305,000 pounds per square inch (psi)) as measured by ASTM D-790, the composition comprising based on the total weight of the TPO composition: A) 36-56 wt % of a crystalline polypropylene having a MFR of at least 1 and a melting point (Tm) of at least 160° C. as measured by differential scanning calorimetry (DSC); and B) 64-44 wt % of an EAO elastomer/filler composition comprising (1) an EAO elastomer having a (1) Tg of less than −50° C. as measured by DSC, (b) tan delta between greater than 2 and 3 as measured at 0.1 rad/s and 190° C. with an Advanced Rheometric Expansion Systems (ARES) rheometer, and (c) HDT greater than or equal to the peak melting temperature of the EAO elastomer as measured by DSC, and (2) a platy filler, the EAO elastomer and filler present at a weight ratio of EAO elastomer to filler of 3:2 to 2:1; the crystalline polypropylene and EAO elastomer present at a weight ratio of polypropylene to EAO elastomer of less than 2.
