Fraunhofer Institutes develops Biomimetic SR with optimised abrasion behavior

Fraunhofer Institutes has developed a Biomimetic synthetic rubber with optimised abrasion behavior which will achieve 30 to 50 percent less abrasion than natural rubber.

The global tyre industry is facing volatility in supply of natural rubber. However,  synthetically produced rubber, on the other hand, has not yet been able to match the abrasion behavior of the natural product, rendering it unsuitable for truck tires. But now, for the first time, a new type of synthetic rubber has been developed that achieves 30 to 50 percent less abrasion than natural rubber.

In view of this threat, researchers at the Fraunhofer Institutes for Applied Polymer Re-search IAP, for Microstructure of Materials and Systems IMWS, for Molecular Biology and Applied Ecology IME, for Mechanics of Materials IWM and for Silicate Research ISC have now optimized the characteristics of synthetic rubber. “Our synthetic rubber BISYKA – that’s a German abbreviation for “biomimetic synthetic rubber” – actually has superior characteristics to natural rubber,” says Dr. Ulrich Wendler, who heads up the project at the Fraunhofer Pilot Plant Center for Polymer Synthesis and Processing PAZ in the German municipality of Schkopau.

Fraunhofer PAZ is a joint initiative be-tween Fraunhofer IAP and Fraunhofer IMWS. “Tyres made of the synthetic rubber lose 30 percent less mass than equivalent tyres made of natural rubber. On top of that, the synthetic tyres have only half the tread loss. Furthermore, the synthetic rubber can be produced on an industrial scale using existing plants and equipment. This means that the synthetic rubber offers an excellent alternative to natural rubber – including the do-main of high-performance truck tyres.”
