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.




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



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.
