Time: 8:00 AM - 5:00 PM
Location: Akron Polymer Training Center, Akron, OH 44325-5404, U.S.A.

The Rubber Technician Training Course is a beginning course for new rubber technicians, a beginning course for sales engineers and managers or a review course for seasoned rubber lab technicians. There are 16 hours of classroom instruction and 16 hours of focused lab testing.
The classroom instruction focuses on ASTM procedures for testing of elastomers and elastomer formulations. Rubber technology concepts are also developed to lay a foundation for understanding more completely what the test data means and how it is used in the characterization of rubber materials. The subjects that will be covered will include:
- calculations used in the rubber lab,
- compound formulations and compounding ingredients
- density and specific gravity
- the use of mixing schedules during rubber compounding
- determining cure characteristics using the MDR
- determining rubber viscosity using the Mooney viscometer
- molding techniques used to effectively prepare test samples
- effective preparation of viable rubber testing samples
- properties of elastomers in tension using the tensometer
- tear properties of elastomers
- hardness measurements
- stress relaxation and creep in rubber materials
- dynamic properties of elastomers using the DMA
- decomposition properties of elastomer materials using the TGA
- thermal properties of elastomers using the DSC
- chemical structures and overall properties of general purpose elastomers
- chemical structures and overall properties of common cure accelerators
- elasticity as it relates to elastomer structure and composition
The lab sessions will include testing that mirrors the classroom topics. Each lab group of two will mix and test their compound for specific gravity, hardness, cure characteristics, resilience, compression set, tensile and tear properties, hysteresis, stress relaxation, Mooney viscosity, volume change and deteriorative properties in contact with fluids, decomposition characteristics using the TGA , and characterization of an eleastomers thermal properties using the DSC. For the final 2 hours of the class, each student will report their values for each of the test performed in the lab session and there will be a discussion about how the test results trend with regard to the elastomer type and makeup.
Mr. Robert Seiple obtained a Masters in Polymer Science in 1984 at The University of Akron. He was the Assistant Manager of the Applied Polymer Research Center (APRC) at UA from 1984 till 1989 and the Manager of APRC from 1989 till 2011. During this time period, APRC performed over 10,000 projects for industry and government organizations. The projects focused primarily on plastics and rubber testing.
In 2008, Mr. Seiple became involved in a joint project between The University of Akron, Exxon Mobil and SABIC to develop a training institute in Saudi Arabia focused on rubber technology for rubber technicians. His tasks were to train Saudi Instructors and Lab Technicians at UA in rubber technology concepts, help to develop an appropriate training curriculum, prepare training modules to be used to train elastomer technicians at the institute in Saudi Arabia, provide specifications for $20M in rubber conversion and testing equipment and to design and assist in the implementation of modifications to facilities at the new institute to accommodate the equipment . In 2011, Mr. Seiple left his position as Manager of APRC to become fully engaged in the Saudi Arabian project.
Mr. Seiple has also been the instructor for the Rubber Technician Training Course (RTTC) for the past 25 years at the Akron Polymer Training Center. During this time period, he has presented his course to over 900 workforce training students.
