Abstract:
This invention relates to a film or sheet and a process to make a film or sheet having a thickness of 0.5 to 35 mils comprising a blend composition comprising: a) 4 to 50 wt % of one or more polypropylene-based TPO(s); and b) 30 to 80 wt % of one or more ethylene plastomer(s); and c) 0.5 to 35 wt % of one or more non-functionalized plasticizer(s) having a kinematic viscosity at 100° C. of 4 to 300 cSt, a pour point of −20° C. or less, and a flash point of 200° C. or more; and d) 0 to 69.5 wt % of one or more filler(s); and wherein the blend composition is calendered into a film or sheet.
