Description: Natural Rubber is mostly used in blend with other general-purpose as well as specialty elastomers for various applications including Tyres, Footwear, Belting, Waterproof Clothing etc. In most of the cases the Mooney Viscosity of synthetic elastomers is far lower than natural rubber because of the inherent nervy characteristics of the latter. This is because of the high molecular weight & dense entanglements of the molecular chains of natural rubber. This difference in the mooney viscosity of natural rubber & the compatible synthetic elastomers causes difficulties in proper dispersion as well as distribution of the reinforcing fillers & other compounding ingredients in the two phases. In order to bridge the gap between the mooney viscosity of the two elastomers phases, the ingredient used is termed as “Peptizer”. This webinar is aimed to highlight various types of peptizers, their effectiveness, mode of action etc. The whole discussion is based on the practical data.
Speaker: M. Hamid Iftikhar. Polymer Engineer by profession. Has also completed the Post Graduate Diploma in Polymer Engineering. Around 15 years’ experience in rubber compounding for tyre industry. Currently working as Senior Manager (Compounding & Development) in Panther Tyres Limited which is the leading tyres & inner-tubes manufacturing industry in Pakistan.

Description: Lately, interest in the high strain rate behaviour of polymer matrix composites (PMCs), under a high strain rate loading, has increased continually. The main reason for this is due to the PMCs capability to provide a good balance between impact resistance, production cost, and weight. In addition, the commercial importance of PMCs means that they have been broadly used in a variety of engineering applications, such as aircraft, construction and automotive components. However, all of these applications are mainly subjected to dynamic loadings. Hence, it is crucial to investigate the high strain rate behaviours of PMCs, in order to avoid any mishaps during service. In existing works on high strain rate deformation behaviour, attention has been highly focused on polymeric virgin materials. However, the influence of the particulate fillers and continuous fibers, on rate sensitivity and dynamic behaviour, has not been considered often. Therefore, this is a great opportunity to discover the capabilities and possibilities of PMCs, to replace conventional materials; especially in high strain rate applications. In this paper, the mechanical behaviour of various polymer matrix composites at high strain rate are presented and discussed under compression configuration of split Hopkinson pressure bar apparatus with several equations for prediction purposes. The discussion also contains some essential aspects of the machine's fundamental enhancements and advantages of split Hopkinson pressure bar apparatus for polymer matrix reinforced composite specimens. Directions for future research and development were also discussed.
Speaker: Dr Omar M.F. is an Associate Professor in the Faculty of Chemical Engineering Technology, Universiti Malaysia Perlis and a research fellow at Center of Excellence Geopolymer & Green Technology (CeGeoGTech), where he leads research on dynamic mechanical properties of materials especially on polymeric based materials. His current research interests include synthesis and characterization of various polymer matrix composites (PMCs) concerning their high strain rates and tribology properties. He is a professional engineer, professional technologist as well as chartered engineer of Board of Engineer Malaysia (BEM), Malaysia Board of Technologist (MBOT) and Institute of Materials, Minerals and Mining, United Kingdom, respectively. He was the recipient of the book prize under R&D category from the Malaysian Ministry of Higher Education in 2015. Meanwhile, from 2014 to 2016, He was appointed as the Honorary Associate Researcher from the Georghe Asachi Technical Universiti of Iasi, Romania. Until recently, he has authored over 100 scientific papers on related topics and has been invited for over 30 events/conferences as an invited/keynote speaker.

Description: Graphene, the newest member of the carbon allotrope family is commonly known as the mother of all carbon nanomaterials. Graphene has been an excellent model material for examining the issues of materials chemistry and physics ever since its breakthrough discovery by Geim and Novoselov. It has attracted significant attention due to its atomically thin dimension and distinctive electronic, optical, and mechanical properties. In the recent past, there has been a growing interest to use graphene as a potential filler in polymer science and technology. In this lecture, the basics of graphene chemistry and how to effectively disperse graphene in a polymer matrix will be discussed. Further, different characterization tools commonly used to quantify graphene dispersion in the polymer matrix will also be addressed. Lastly, a reverse strategy to effectively synthesize graphene or its derivatives from polymeric sources will also be discussed.
Speaker: Dr. Titash Mondal is currently working as an Assistant Professor- Grade I at the prestigious Indian Institute of Technology (IIT), Kharagpur. Dr. Mondal obtained his BSc and MSc in Chemistry from the University of Calcutta, M-Tech in Rubber Technology from Indian Institute of Technology Kharagpur and PhD in Chemistry with specialization in carbon nanomaterials and polymer materials. His PhD work was carried out as a joint Ph.D. program between the Indian Institute of Technology and the University of Houston, United States of America. Dr. Mondal has authored 17 peer reviewed publications in international journals, 7 book chapters, and a 3 USA and 1 Indian patent. Before joining academia, Dr. Mondal has worked for Momentive Performance Materials (Formerly GE Silicone), a world leader in the silicone-based products market, as a Research Scientist in the Corporate R&D for close to 4 years. His domain expertise in the industry was in the field of application of specialty polymer and their composition for application in autonomous vehicle, electric vehicle. For the last ten years, Dr. Mondal has been working on graphene and different graphene/graphite derivatives for specialty applications.
