Centre for Advanced Polymer Processing and Design (CAPPA-D)


The CAPPA-D is involved in research, education and technology transfer in the area of polymer processing and rheology. Projects involve formulation, conversion, and characterization of plastics, mathematical modeling of single and twin screw extrusion, coextrusion, injection molding, thermoforming, rotational molding, film blowing, reactive extrusion, mixing, and coating.

Funding is provided in the form of research grants and contracts from NSERC of Canada, Centres of Excellence (Ontario) and several corporations from Canada, USA, and overseas.
