Investigations of the potential of suitable polymer blends on thermal oxidative aging stability of polydienes

Elastomer materials are very important for the production of dynamically high loaded, temperatur- and media resistant products. The life time of elastomer products is depending to a great extend on material homogeneity beside their construction and the mechanical load and chemical exposure during use.

Cumulative Damage in Rubber Materials – Benchmark and Further Development

This project is motivated by components loaded in service. These real-life loadings are rarely of continuous cyclic constant amplitude nature. In daily use, rubber components are exposed to all kinds of  loadings. However, the lifetime of such components is often predicted using fatigue data from simple test pieces which were exposed to continuous cyclic loads with constant amplitude.

Impact of Filler Dispersion on Mechanical Performance and Lifetime of ‎Elastomers

The project aims are to develop and improve methods for the analysis of lifetime relevant particle size ‎distributions in filler reinforced rubber compounds. This is promising to reduce the development costs for ‎high-performance compounds, especially considering durability.‎ In compounding and further manufacturing of elastomer parts, the filler dispersion is well known as a ‎crucial property for the final article performance.

Efficiency of antiozonants in rubber matrices - Regulation of p-phenylenediamines

Elastomer materials are mandatory for temperature and media-resistant components which are under dynamical load. Their service life is significantly influenced by external factors such as the effects of ozone, oxygen and temperature, as well as the load spectrum. These influences lead to function-limiting material changes that are irreversible and, in the worst case, can lead to the failure of a component.
