GGPF is proud to announce a short 2-day course covering crystallization and mechanical behavior of polymers and taught by a well-known instructor. The objective of this course is to provide a detailed introduction to structure-processing-property relationships in polymers, with an in-depth review of crystallization and mechanical properties. The attendees will learn about the important aspects of crystallization and mechanical properties of polymers and how they relate to conventional polymer processing, with emphasis on practical applications. The concepts covered in this seminar will serve as valuable tools for material selection and process optimization, and will help polymer users to predict material performance.



Engineers and technicians, scientists, product development and R&D personnel who are using polymers, but who do not have formal training in polymers; or those who would like to have a concise refresher from previous course experience. Also, those who wish to get an in-depth introduction to polymers, with emphasis on mechanical properties and structure-processing-property relationships and how a desired set of properties can be achieved through an optimization of material and process parameters.

Pravin Soni has a BS in Chemical Engineering and a Ph.D. in Polymer Science from Case Western Reserve University. His research and development interests include structure-processing-property relationships, crosslinking, crystallization, and mechanical and electrical behavior of filled and unfilled polymer systems, medical applications of polymers, and development of medical devices and drug delivery systems. He has co-authored nineteen (19) papers and fifty seven (57) patents on these subjects, and has taught courses in polymer physics at Society of Plastics Engineers' meetings. Dr. Soni is Founder and President of Pharmacro, LLC, providing consulting services for the development of medical devices, drug delivery systems and combination medical products.
