Rotational molders now can use more grades of post-industrial polyethylene in their products, according to researchers from McMaster University and specialty polymers firm Synergy Polymers Inc.
Until now, the finicky rotomolding process primarily has been limited to reprocessed rotomolding grades of PE as feedstock. Limited availability of that material has been a roadblock for some firms seeking government jobs that require higher recycled content.
But the researchers found that rotomolders can use blow molding and film grades of PE, provided they are blended with metallocene-based PE, which serves as an impact modifier.
Researchers blended ...
