10, 11, 12, 13 and 14 june 2024
An intensive 5-day seminar for engineers in the rubber industry, suppliers and users.
From January 2024 on it will be possible to subscribe for this course again.
Who is this course intended for?
- young chemists and mechanical engineers
- higher technical education graduates with work experience in the rubber industry
- designers/constructors in companies that utilize rubber components or parts
Which topics and problems will be dealt with?
- Production problems are resolved all too often by trial and error. Is a better knowledge or understanding of the rubbers and available processes of help?
- Every user employs own specifications. How can we best translate these into useful material specifications?
- Mixing is crucial for the production of good rubber compounds. Is one mixing technique better than another?
- Which method of vulcanization is most suitable for our product? Or should we employ thermoplastic rubber?
- How can environmental issues be prevented in the rubber industry?
Course structure
Rubber technology is an intensive seminar given from experts from the University of Twente and from the industry. A tour of the Apollo-Vredestein factory is included in the programme. It is at the discretion of the hosting factory to decide upon admission of the individual persons. Additionally, a tour of the ETE laboratories is included. Case studies are used to discuss the application in the company environment. There are plenty of opportunities provided for discussion of theoretical and practical aspects with the lecturers. Also after the seminar the participants can obtain advice from the University of Twente.
Speakers
All speakers are experts with very long experience in their fields, and they gained their expertise either in industry or academia.
