Rubber Technician Training - 4 Day Course
Course Number: AP3388
Date: 09/10/2018 - 09/13/2018
Time: 8:00 AM - 5:00 PM
Location: Akron Polymer Training Center, Akron, OH 44325-5404, U.S.A.
Cost: $2,000.00 USD
Instructor: Mr. Bob Seiple
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. The subjects that will be covered will include:
- calculations used in the rubber lab,
- compound formulations
- density and specific gravity
- mixing schedules
- MDR and RPA testing
- Molding test sheets
- Properties of elastomers in tension
- Tear properties
- Hardness testing
- Stress relaxation
- DMA testing
- TGA testing
- DSC testing for Tg
The lab sessions will include testing that mirrors the classroom topics. Each individual will mix and test their compound for specific gravity, hardness, cure characterization using MDRs, tensile and tear properties, TGA, DSC and DMA. 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 on plastics and rubber technologies.
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 and to provide equipment specifications and to design the lab facilities at the new institute. 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 20 years at the Akron Polymer Training Center. During this time period, he has presented his lecture this course to over 700 workforce training students.Click to view Course Outline
