Description: This webinar on Viscoelastic Properties of Polymer Materials and Their Measurements provides an introduction to solid polymer materials and their time, frequency and temperature dependent properties. These properties play an important in the long term durability of polymer components. The webinar provides a review of the basic theory, how the materials are experimentally characterized, and how to analyze and predict their behavior under different service conditions.
Speaker: Mr. Kartik Srinivas is a consulting mechanical engineer with extensive background and experience in product engineering using simulation technologies and mechanical and materials testing. He started his career as a consulting Mechanical/FEA Engineer at Akron Rubber Development Laboratory, Akron, Ohio, USA. In a career of over a decade and half in USA and at Advanced Scientific and Engineering Services (AdvanSES) India, Kartik has advised and assisted companies solve engineering problems related to materials and product design. Kartik provides material and design development, material testing, Finite Element Analysis (FEA) solutions to a broad range of industries and is well versed with material and product testing as per ASTM and ISO standards.

Description: This webinar will discuss about the dynamic functional characteristics of single-screws used in polymer extrusion processes. Understanding these characteristics will enable us (1) to have more appropriate considerations in designing and selecting screws, and (2) to appreciate the functional limitations of a specific design. This webinar will also include discussions on screws of different configurations for different purposes.
Speaker: Dr. Anthony Wong obtained his B.Tech (Hons) and Ph.D degrees in Chemical Engineering from University of Bradford, U.K.. Prior to taking up his academic duties at The University of Hong Kong, he was with BASF and Exxon Chemical as the technical support to their sales team of their plastics department for the Asia Pacific region. In his 20 years of employment at The University of Hong Kong, he taught at both undergraduate and postgraduate levels, and was also actively engaged in carrying out research work in plastics technology. Main areas of his research focuses include extrusion technology, polymer rheology, powder technology, and environmental engineering. In 2003, he joined NHH Co. Ltd. (a color compounder listed in Hong Kong) as its Vice Chairman and Director, responsible for the company’s technology and market development. He left NHH in April 2019 and is now the Asia Pacific market coordinator for Badger Color Concentrates, Inc., a US based color compounder.

Description: The importance of rheological properties of polymers is well recognized by engineers and scientists in the polymer processing industry. Issues such as whether or not a plastic product would have the expected designed performance, or whether or not a manufacturing process could be optimized etc. are closely related to the overall rheological behaviors of the involved polymetric system. This webinar is designed to discuss how the physical properties of the solid raw materials such as additives, fillers etc. commonly used in the industry could affect the important rheological behaviors (such as die swell and slip velocity) of the polymeric system during extrusion.

Description: This webinar is designed to help the polymer scientist characterize polymeric materials using a variety of Thermal Analytical (TA) techniques like Differential Scanning Calorimetry (DSC), Thermal Mechanical Analysis (TMA) Thermogravimetric Analysis (TGA, and Dynamic Mechanical Analysis (DMA). Discussions about important experimental considerations for each technique will be presented. In addition, discussions about choosing the correct technique to solve a specific product development or processing problem will be presented via specific TA examples. We will also discuss thermal transitions for amorphous and crystalline polymers and how thermal history influence interpretation of TA data. The presentation agenda is as below: # Thermal Analysis Instrumentation # Experimental Considerations # Thinking Beyond Standard Analysis # Industrial Problem-Solving Case Studies
