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.

Polyolefin compositions with high dimensional stability for sheet applications

Compositions comprising post-consumer recycled (PCR) waste are described. The PCR is combined with at least one virgin resin and a propylene-based compatibilizer that enhances the blend between the PCR and virgin resin as well as improving one or more physical properties of the composition. The propylene-based compatibilizer is a reactor made thermoplastic polyolefin or a heterophasic copolymer with a semi-crystalline matrix and a rubber component. This allows for the selection of a compatibilizer that can shift the composition's physical properties based on the end use application, and provide a stronger, miscible blend.
