Rubber Technology Seminar 2021

22, 23, 24, 25 and 26 NOVEMBER 2021

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

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.


All speakers are experts with very long experience in their fields, and they gained their expertise either in industry or academia. 



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 tires.


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 vulcanization, sulfur, peroxides, types of crosslinks, crosslinking reactions, cross link density, additives, zinc oxide, vulcametry.
