Description:
Thermoset polymers form the matrix in filled plastics and fiber-reinforced composites used in a diversity of products. These range from consumer items and auto body panels to advanced composites for printed circuit boards, aerospace structural components, and expensive, high-performance sports equipment. Rheological measurements have become the most important characterization technique because of their sensitivity to small changes in structure and the ease to monitor these structural changes. For the thermoset polymers, rheology (including dynamic mechanical analysis) provides details of structural changes, the gel point, and also processing parameters such as viscosity as a function of time. The advantage of the rheological technique is that it allows probing of the sample during the reaction with a small oscillatory deformation, which can generate viscoelastic material properties, such as the storage modulus, the loss modulus, and the tan delta all of which are characteristic of the changes of the material’s structure during cure. The KnowHow Webinar will demonstrate the various applications of the rheological characterization technique in the thermosetting polymer to predict its process behavior and how to evaluating its product performance.
Expert:
Dr. Raj Ganesh J. has more than 15 years of experience in the field of polymeric materials characterization techniques and their processing techniques. His major expertise is in the study of structure-property relation of polymeric materials, processing relevant material characterization, material property correlation with the processing behaviours, processing related modelling & simulation techniques. As a qualified Application Expert, he has been providing technical support to various industrial customers from plastics, composites, rubber, and adhesive-related industries in the field of thermal, rheology, and thermophysical property measurements and supporting to resolving the processing related issue by the appropriate material testing solutions. He has conducted several applications-focused technical workshops at various locations in India as well as south-east Asia and, he has participated in various international conferences as a speaker. He has obtained his Master of Science (MS) in Polymer Engineering and Science and Ph.D. in Polymer Processing from the Montanuniversität Leoben (University of Leoben), Austria, Europe. Presently, he is working with TA Instruments, A Division of Waters LLC in India as an Applications Support Manager for the last 9 years.
