Department Elastomer Chemistry (EC)

In terms of content, Elastomer Chemistry (EC) covers the areas: chemical material characterization and microscopy. Because of the issues involved, microscopy collaborates closely with the other departments at DIK. Equipped with cutting-edge technology for spectroscopy, chromatography, thermoanalysis, and electron microscopy, the department is able to guarantee thorough execution of the numerous commissioned assignments and research projects entrusted to it on the most diverse issues on elastomers, polymers, raw materials and uncured compounds. The unit‘s more than 20 highly qualified and experienced technicians and researchers provide work of the highest level.

Topically, the overall range of research focal points is quite diverse. It includes the development of new materials, studies of aging mechanisms, crosslinking, methods development, characterization of multiphase systems (morphology) and of rubber/filler interaction, elastomer emissions and environmental exposure, processes for transporting gases and fluids in elastomers, and recycling.
