Basic Rubber Compounding Course

To be held on February 24 & 25, 2020.

€1,075 plus German VAT for the two-day course. CAN BE BOOKED ON ITS OWN

The Basic Rubber Compounding Course will be held concurrently with Tire Technology Expo 2020 in Hannover, Germany, on February 24 & 25, 2020 – commencing one day before the expo and main conference. It will be presented by Mike Beeson AIMMM, former senior scientist, Dunlop Tyres UK, and John Bowen MIMMM, BSc, a 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.
