Abstract:
1. A plasticized polyolefin composition comprising from 99 wt % to 60 wt % polyolefin; and from 1 wt % to 40 wt % of a non-functionalized plasticizer; wherein the non-functionalized plasticizer comprises C 6 to C 200 paraffins having a pour point of less than −30° C. and a kinematic viscosity of from 10 cSt to 500 cSt at 100° C. and wherein elastomers are substantially absent from the composition, and wherein the polyolefin has a 1% secant flexural modulus of 100 MPa to 2300 MPa and is selected from propylene homopolymers, propylene copolymers, propylene impact copolymers, or mixtures thereof, where the propylene impact copolymers are reactor blends, wherein polyethylene homopolymer and copolymer having a weight average molecular weight of from 500 to 10,000 is substantially absent from the composition.
