Rotational Molding of Polyolefin Plastomers and TPOs
Wenqing Wang and Marianna Kontopoulou Department of Chemical Engineering, Queen’s University, Kingston ON K7L 3N6, Canada
The present research aims at examining the rotational molding characteristics of metallocene catalyzed Polyolefin Plastomers (POPs) and Thermoplastic Olefins (TPOs). The latter are blends of polypropylene with POPs. The rheological and thermal properties of two grades of POPs and a TPO in powder and micropellet form have been tested and their processability has been assessed by conducting sintering and rotomolding studies. Depending on their formulation, POPs can be successfully rotomolded and excellent properties can be obtained. Rotomoldable TPO resins should have low zero shear viscosity and low melt elasticity.
