Online Rubber Technology Seminar 2021

  • Would you like to give a young employee or “newcomer” the possibility to deepen his/her knowledge about rubber? 
  • Would you yourself like to learn more about rubber? 

Then we have the right offer for you: Join our online rubber technology seminar!

The course is spread over one month, to enable you or your employee to easily combine the training with daily work. It will consist of 15 online afternoon sessions from mid May until mid June 2021.


  • 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


  • 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. It is partially based on the book “Basic Elastomer Technology” (Rubber Division, American Chemical Society). 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 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.

Vulcanization systems

Comparison of sulfur and peroxide vulcanization, difference in rubber properties, choice of system.


Basic principles, bonding to plastics and steel cord.

Mixing technology

Appearance of raw materials, mixing rate and mixing quality, distributive and dispersive mixing, degree of dispersion, mastication, mixer types including mills and internal mixers, the mixing process in the internal mixer, energy balance, organization of a mixing shop.

Properties of rubbers

Material properties of vulcanized rubbers, standards, measurement methods.

Properties and applications
