SPECIFIC DATES ARE YET TO BE DETERMINED.
An intensive 4-day seminar for engineers in the rubber industry,
Suppliers and users
WHO IS THIS COURSE INTENDED FOR?
- 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
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 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?
ELASTOMER RESEARCH & TESTING B.V.
This seminar is part of a more comprehensive set of courses offered for general practice and operations in the rubber industry:
- Introduction to rubber technology (2 days)
- Rubber in sealings (1 day)
- Practical rubber workshop
offered by Elastomer Research & Testing B.V.
Rubber technology is an intensive seminar. We ask the course members to bring a laptop because the syllabus will be provided via USB flash-drive. It is partly based on the book “Basic Elastomer Technology” (Rubber Division, American Chemical Society). A tour of the Apollo Vredestein tyre assembly factory is included in the programme. 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.
GENERAL PURPOSE RUBBERS
- 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.
Comparison of sulphur and peroxide vulcanisation, difference in rubber properties, choice of system.
