CANCELLED: Rubber Technology Seminar 2020

Due to currently again growing health concerns about COVID-19 pandemic, this edition of the Rubber Course was cancelled. As soon as we have more news on the next edition of the course you can find it on this page.

16, 17, 18, 19 and 20 NOVEMBER 2020

An intensive 5-day seminar for engineers in the rubber industry, suppliers and users.


  • young chemists and mechanical engineers with limited polymer background
  • higher technical education graduates with work experience in the rubber industry
  • designers/constructors in companies that utilize rubber components or parts


  • 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 the one mixing technique better than the other?
  • Which method of vulcanisation is most suitable for our product? Or should we employ thermoplastic rubbers?
  • How can environmental issues be prevented in the rubber industry?

course structure

Rubber technology is an intensive seminar. It is partially based on the book “Basic Elastomer Technology” (Rubber Division, American Chemical Society). 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. In such case a tour of the ETE laboratories will be included instead. 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.



Types of polymers, thermoplastics, thermosets, rubbers/elastomers, rubbers versus plastics, modulus versus temperature and time, glass transition, rubber elasticity, reinforced and non-reinforced rubbers.


  • Carbon black: sorts, properties and effect on rubber.
  • Non-black fillers: types, properties and effects on rubber, influence on the polymer networking processes.


  • Properties of general purpose rubbers (NR, SBR, BR, IIR).
  • Rubbers for car tyres.


Oil resistant and heat resistant rubbers (NBR, CR, ACM, CO, ECO, FKM, Q, FVQ).


  • TPE's made from block copolymers, structure and properties.
  • TPE's made from blends, particularly on the basis of EPDM and PP.


Introduction to the mechanics of vulcanisation, sulphur, peroxides, types of crosslinks, crosslinking reactions, cross link density, additives, zinc oxide, vulcametry.

Vulcanisation systems

Comparison of sulphur and peroxide vulcanisation, difference in rubber properties, choice of system.


Basic principles, bonding to plastics and steel cord.

Mixing technology
