BISYKA - Innovative rubber for the automotive industry
In the Fraunhofer "Biomimetic synthetic rubber BISYKA" project, the causes of the unique mechanical properties of natural rubber were explored and transferred to synthetic rubber.
Rubber in the automotive industry
Natural rubber is an important raw material for the treads of truck tires.
Fungal infestation of rubber trees is threatening global rubber production.
Until now, synthetic rubber has caused more abrasion than natural rubber.
What makes natural rubber unique?
Natural rubber has outstanding mechanical properties due to strain-induced crystallization
Causes: high microstructure purity, specific biocomponents
Analysis: specific biocomponents make natural rubber unique.
From natural rubber to synthetic rubber
BISYKA rubber contains functionalized, highly microstructurally pure polyisoprene and relevant biocomponents and was synthesized on a pilot scale.
Silica fillers for the rubber and tire industry
Colloidal silica nanoparticles enable a previously unattainable precision in the adjustment of agglomeration and aggregation behavior.
Friction and wear
A new method for assessing abrasion resistance shows that BISYKA rubber comes close to the abrasion resistance of natural rubber.
Strain-induced crystallization
The BISYKA compound has a degree of crystallization comparable to the natural rubber-based compound. This goes hand in hand with excellent abrasion resistance.
BISYKA tire compound in the field test
Test report from Test Laboratory North: »The tires with the color code green (= BISYKA) showed better results in all evaluation points.«
