Tire Technology Expo 2018
2 days
Basic rubber
compounding course

The Basic Rubber Compounding Course will be held concurrently with Tire Technology Expo 2017 in Hannover, Germany, 13 and 14 February 2017 – commencing one day before the expo and main conference.

Presented by Bob Kind MIMMM, GPRI, technical director of Polymer Recyclers UK; and John Bowen MIMMM, BSc, consultant formerly of Robinson Bros Chemicals UK. This basic course is designed for all those working in the associated tire industry who wish to know more about the compounding of rubber. It will try to define the concepts in simple terms, but at the same time relate them to actual manufacturing and product circumstances.

Course Fee
€1075 plus German VAT for the two-day course
