Abstract
A polyolefin composition useful for making sheet membranes, as well as other articles of manufacture are described. The composition polyolefin combines a reactor made thermoplastic (rTPO) with at least one linear low-density polyethylene (LLDPE) to improve the mold shrinkage and thermal expansion force compared to a rTPO-only composition, without affecting other properties.
