Solving Problems in Rubber Compounding and Processing - 1 Day Course
Course Number: AP6217
Date: 06/17/2021 - 06/17/2021
Time: 8:00 AM - 4:00 PM
Location: Akron Polymer Training Center, Akron, OH 44325-5404
Cost: $1,000 USD
Instructor: John Dick
This course is crucial for anyone in the rubber compounding field. It provides an in-depth look at processing problems in mixing, extrusion, calendering and molding. Statistics and methodologies for solving factory problems and case studies are covered as well. Participant’s current processing problems can be discussed with the instructor. The course includes a copy of John Dick's book, How to Improve Rubber Compounds (Hanser Publications).
How to Improve Rubber Compounds - 2nd Edition by John Dick
John S. Dick, a senior rubber scientist with Alpha Technologies, has over thirty years of experience in the rubber industry. Mr. Dick has authored over 50 journal and magazine publications and four books on polymer technology. He received the Monsanto Master Technical Service Award in 1994, the ACS Rubber Division Best Paper Award in 1995 and a University of Akron Appreciation Award in 1998 for Teaching Polymer Compounding Courses in their Continuing Education Program. He is a Fellow of ASTM International receiving the Award of Merit in 1990. In addition, he has represented the United States as a delegate to the ISO for the last 20 years. He was appointed in 1992 to be Leader of the U.S. Delegation to ISO TC-45 on Rubber. Mr. Dick teaches rubber technology courses at both University of Akron and University of Wisconsin continuing education departments. He received his B.S. degree from Virginia Polytechnic Institute in 1970 and an M.A. from the University of Akron in 1979.
