To obtain a top-notch friction material, it is not enough to protect the phenolic resin. Indeed, it is a key parameter the control the performance and wear of the finished product. However, HOW this organic binder decompose is a crucial factor that will determine the comfort and the NVH properties of the pad.  Can we control this? Let’s go deep on that.

We start from the fact that the mentioned phenolic resin transforms into a sticky substrate on the friction surface when it degradates. And, as if it was like a smoker/non-smoker lung, a cleaner surface will help us to avoid groan, noise and vibrations, while obtaining a smooth and stable braking. And how can we do so? The answer is on titanates.

This way, we obtain a cleaner surface and so, when the counterpart contacts the friction material, we do not have that viscous residue between them which, as you might have guessed, will help us to reduce the CoF (μ) amplitude and improve μ stability, which are straightly related with the NVH and groan properties of a friction material.

Nowadays, there are a wide range of titanates with different morphologies and chemical compositions in the market. However, titanates commonly available in friction industry are a fibrous product with health issues. To make them fibre-free either the production costs are increased or they contain other metals on their composition.

On that lead, since 2019 rimsa has join forces with TAM Ceramics to tackle the challenges concerning this particular aspect of a friction material performance with innovative products specially developed for friction industry.
