Course Overview

This course is intended to introduce plastics extrusion process engineering to extrusion operators and supervisors, with particular focus on PVC compounding, as well as on film, sheet and profile extrusion processing. It entails a comprehensive overview of both single screw and twin screw extrusion processing, with detailed design of equipment, including those dependent on material flow characteristics. Rheological properties of polymers and how these relate to extrusion process design will be elaborated. Monolayer extrusion vs. Multilayer co-extrusion and applications thereof will also be elucidated. Finally, a comprehensive troubleshooting guide entailing PVC production and quality issues will be elucidated.

Instructor Biography:


Dr. Sylvain Seif has over 15 years of industrial R&D experience in Polymer Engineering, spanning several different areas in the field, and over 12 years of academic teaching experience. He completed a BS in Mechanical Polymer Engineering in 2005 followed by a PhD in Polymer Engineering degree in 2009 from The University of Akron in OH, USA. After graduation, he joined INDEVCO Group, a multinational packaging and consumer goods firm, starting up an R&D Center called “PACT”- Polymer Application Center for Technology- for the entire flexible packaging and compounding divisions of INDEVCO, which consists of 10 manufacturing facilities spread across the globe. He has also taught several engineering courses at the university level, and started R&D collaborations with 5 different universities, refereeing over 30 Masters and Final Year Projects, and being a jury member on all these projects. In 2017, as Senior Technical and R&D Expert at PACT, he helped the INDEVCO R&D Center attain ISO 17025 accreditation for lab testing.

Since 2022, Dr. Seif has been working at an environmentally conscious start-up company, Novoloop, in California, managing the polymer processing lab; having expertise in operating the twin screw compounder, injection molding and co-extrusion cast film machines. Here, he optimized the processing and properties of various durometer TPUs, whereby the polyester polyols are derived from PE recycled waste. He is also very familiar with structure-processing-properties relationships of polymers and their composites, with a strong know-how in lab testing methods for mechanical, rheological, thermal and physical properties. Moreover, Dr. Seif has over 10 academic publications and 3 patents in the polymer field, and has a strong passion for teaching and doing research and development in sustainable solutions.
