Course Overview
Are you challenged to make your rubber products last longer? Rubber compounds are complex mixtures of polymers, reinforcing fillers, oils / plasticizers, curatives, stabilizers, and other additives that are combined in relatively quick mixing processes. Durability is impacted by all these ingredients, their interactions, and the quality of the mixing. This one-day course will teach compounding strategies to improve the strength and lifetime of rubber components. This specialized training will benefit materials engineers, compounders, rubber chemists, product development engineers, R&D scientists, and rubber lab managers at manufacturers of tires and rubber parts and companies that supply raw materials. The objectives of the course are:
- Understand how rubber fatigue and failure characteristics are influenced by materials selection and compound structural features
- Learn compounding strategies to improve strength and fatigue lifetime
- Know the right testing methods to characterize rubber durability efficiently in the lab
Instructor Biography:
Dr. Chris Robertson is an international authority on polymer science and rubber compounding for performance. Chris holds the role of Sales Director and Materials Expert at Endurica LLC, which is focused on elastomer durability software and testing solutions. He brings over 15 years of materials research and product development experience at tire and rubber companies and raw materials suppliers. After receiving his Ph.D. in Chemical Engineering from Virginia Tech in 1999 in the polymer science area, Chris spent two years as a postdoctoral researcher in polymer physics at the U.S. Naval Research Laboratory before starting his industrial R&D career. Chris is co-inventor of 32 patents and co-author of 55 publications in peer-reviewed journals. He received the 2008 Sparks-Thomas Award from the American Chemical Society Rubber Division, and he serves as Associate Editor of Rubber Chemistry & Technology.
