Basic Rubber Compounding Course

To be held on Monday 4 - Tuesday 5 March 2019.

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

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.
