Description:

Cross-linking or vulcanization is a crucial and important step in any rubber product manufacturing process. Several elastomeric properties are enhanced after cross-linking process. Cross-linking rubbers with peroxides has been employed for more than 70 years already since there are several advantages, for instance, its ability to cross-link both saturated as well as unsaturated rubbers, high temperature resistance, good compresion set properties etc. The mechanism of peroxide cross-linking is also less complicated. Besides enhancing the characteristics and kinetics of cross-linking process (peroxide initiated), multipurpose co-agent can also set new network structure; exhibiting distinct features. Judiciously selected peroxide along with co-agents are believed to deliver good balance between processing and properties that are essential for the longivity of a rubbery product. A comprehensive overview on Peroxide/Co-agent cross-linking in terms of the selection of rubbers, level of cross-linkers, chemical nature of peroxide and type of co-agents, compounding techniques, case studies for desining various rubber products, use of multifunctional peroxide, new generation special co-agents etc. will be given. Challenges of peroxide vulcanization will also be touched upon.

Expert:

Professor Dr. Kinsuk Naskar received his Bachelor of Technology (B.Tech) degree in Polymer Science and Technology in 1998 from the University of Calcutta. In early 2000, he completed his M.Tech in Rubber Technology from Indian Institute of Technology (IIT), Kharagpur (Silver Medalist). In April 2000, he joined the University of Twente, The Netherlands as a Ph.D. employee under the supervision of Prof. Dr. Jacques Noordermeer in a project funded by Dutch Polymer Institute (DPI). He received his Ph.D. degree in June 2004. Since August 2004, he joined Rubber Technology Centre, IIT Kharagpur as a Faculty member. Currently he is holding the position of a full Professor. In 2005 he received DPI Patent Award from The Netherlands for his invention. In 2008 he received prestigious Alexander von Humboldt Research Fellowship from Germany and worked in the group of Prof. Dr. Gert Heinrich. In 2016 he received as the first Indian the prestigious Morand Lambla Award in Lyon, France from International Polymer Processing Society (PPS). His fields of interests are: Structure-property relationship of various polymers and synthetic rubbers, rubber compounding and vulcanization, polymer blends and thermoplastic elastomers (TPEs and TPVs), radiation processing and cross-linking, green tyre technology, shape memory polymers, Self healing polymers, thermo-reversible crosslinking etc. He has more than 120 international journal papers, 85 conference papers, 6 patents and 15 book/book chapters. He has already supervised 13 PhD students and 25 M.Tech students. Currently he is the supervisor of 10 PhD students and 6 M.Tech students. He was convenor of several short term courses and International conferences at IIT Kharagpur.
