Patent ID: 8912271

Claim:
A filled thermoplastic polyolefin composition consisting of: (i) from about 1 to about 15 parts by weight of a propylene polymer having a density equal to or greater than 0.885 g/cm 3 , wherein the propylene polymer is a copolymer consisting of propylene and ethylene; (ii) from about 10 to about 30 parts by weight of one or more linear ethylene polymer, one or more substantially linear ethylene polymer, or mixtures thereof characterized as having (ii.a) a density equal to or greater than 0.873 g/cc and equal to or less than 0.885 g/cc and (ii.b) an I 2 of from greater than 1 g/10 min to less than 5 g/10 min; wherein the linear ethylene polymer is prepared by using a metallocene or vanadium based catalyst and the substantially linear ethylene polymer is prepared by using a metallocene based catalyst; (iii) from about 2 to about 7 parts by weight of plasticizer; (iv) from about 60 to about 85 parts by weight of particulate filler; and (v) optionally one or more of a slip agent, an ignition resistant additive, a stabilizer, a colorant, a pigment, an antioxidant, an antistat, a flow enhancer, a mold release, or a nucleating agent; wherein parts by weight is based on the total weight of the thermoplastic polyolefin composite.
