Analysis of the Influence of Elastomers on the Friction Coefficient of Technical Pavements

Research on high-strength polymers has revealed significant correlations between the chemical composition of elastomers and the surface friction coefficient in technical paving applications. This study focuses on compounds based on nitrile rubber (NBR) and thermoplastic polyurethane (TPU), evaluating their wear resistance under repetitive mechanical stress conditions.

The methodology included tensile and compression tests, as well as analysis of the resulting microtexture after simulated fatigue cycles. The obtained stress-strain graphs, such as the one shown below, are fundamental for predicting the material's lifespan in demanding industrial environments.

The results indicate that the addition of precipitated silica fillers modifies the surface friction, increasing the coefficient by 22% compared to standard formulations. This advancement is crucial for the development of safety pavements in high-traffic industrial areas, where adhesion is a critical factor.

The future of materials chemistry points towards functionalized elastomers that respond to temperature changes, automatically optimizing their friction. Renlastik continues at the forefront of this innovation.
