Do you want to better understand the dynamic mechanical data generated by your rubber lab? This two-part course will clarify the reasons for the various temperature, frequency, and strain sweeps that are used in dynamic testing of elastomers (especially filled rubber) and discuss the impact of the viscoelastic behavior on heat build-up and durability of rubber products. We developed this course in response to requests for a specialized training workshop to 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.
Our 2021 Courses are Online and Live!
Our live, online version of Viscoelastic Effects in Elastomers and Impact on Durability features the live lectures and insights of Dr. Christopher Robertson. This course is a LIVE training event and a link to the presentation of each class will be made available to registrants for their reference/review. These links will be active for seven days after the class date so attendees will have time to make up classes they may not be able to attend live. This course will NOT be distributed or broadcast beyond this time period.

Course Objectives
- Know the key viscoelastic signatures of rubber and how to characterize with testing
- Learn about self-heating (heat build-up) in elastomers
- Understand how strength and fatigue lifetime are affected by viscoelastic dissipation (hysteresis) and temperature
Format
This two-day course includes lectures and classroom exercises focused on understanding viscoelasticity and its impact on strength and fatigue of rubber materials.

Instructor
Dr. Chris Robertson is an international authority on polymer science and rubber compounding for performance. Chris has a combined commercial and technical role as Sales Director and Materials Expert at Endurica LLC, which is focused on elastomer durability software and testing solutions. His background includes 18 years of R&D experience as a materials engineer and technical manager in the tire, synthetic rubber, and plastics industries, including 9 years developing leading-edge polymers and rubber compounds at tire manufacturers (Bridgestone; Cooper Tire). After receiving his Ph.D. in Chemical Engineering from Virginia Tech in 1999 in the field of polymer science, 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 the co-inventor of 34 patents / patents pending, co-author of 63 publications in peer-reviewed journals, and he serves as Editor-in-Chief of the journal Rubber Chemistry and Technology.
