TechnoBiz holds KnowHow Webinar on tire innerliners and butyl rubber

Bangkok, Thailand – KnowHow Webinars announces a webinar led by Dr. Brendan Rodgers will be held on July 7.

Tire Innerliners and Butyl Rubbers will be held July 7 at 10 a.m. CST/5 p.m. CEST/10 p.m. Thailand. The innerliner is one of the most important components in a tire. This is due to the fact the innerliner must ensure tire inflation pressure retention. Loss of inflation pressure will cause a decrease in tire durability due to excessive casing flexing as it rotates under load, increased vehicle fuel consumption due to increased rolling resistance, and loss of traction and wear performance. And this is even more important with the new generation of electric vehicles. The innerliner is based in halobutyl rubber. Bromobutyl has become the preferred polymer due to the better innerliner to tire ply compound adhesion. All of the new global butyl rubber production over the last ten years has been for bromobutyl for this reason. Butyl based compounds are difficult to process due to the need to isolate and prevent contamination of other tire compounds. Manufacturing operations are therefore designed for this purpose. However, halobutyl compounds are relatively easy to process, they only require two-stage mixing processes, extrude easily and when plied up with a barrier before tire building, handle well in manufacturing. This discussion will overview butyl and halobutyl rubbers, compounding and impact on tire performance.

Dr. Brendan Rodgers, based in Austin TX, has spent 42 years working in the tire and rubber industry with both The Goodyear Tire & Rubber Company and ExxonMobil. He has worked on a broad range of tire and industrial rubber products, including hydraulic hose and conveyor belts, materials technology and product design. He has had work assignments in the United States, China, Ireland, Italy and Luxembourg, working on original equipment automobile tires, truck tires, industrial rubber products and new tire materials technologies. He is the originator of a broad range of patents in tire and rubber technology and many industry publications, including editor of the text, Rubber Compounding, Chemistry and Applications, and the text, Tire Engineering, both published by CRC Press. Brendan has a Ph.D. in chemical engineering from The Queen’s University of Belfast in Northern Ireland, where he studied thermodynamics, heat transfer through large rubber sections and vulcanization kinetics. He has a Master’s degree in Polymer Technology also from The Queen’s University, and a B.Sc. in Biological Chemistry from The University of Ulster.
