The future of Mobility

is closely related to the fight against climate change, through the limitation of emissions of all kinds to conclude with the complete electrification of the mobile fleet. In the context of the Green Deal and the objectives of "carbon neutrality" and "zero pollution", the European Commission has committed to reducing current emission limits, from all sources. Brake wear is a significant contributor to respirable particulate matter (PM10 and PM2.5), particularly in areas with high traffic density and frequent braking, and up to an 80% of these particles may come from the wear of the rotor (Grey Cast Iron), and are mainly formed by Iron Oxide. In electric vehicles, the lack of use of the mechanical brake due to the existence of regenerative braking means the appearance of new problems with the use of gray cast iron discs, such as corrosion, which generates noise and safety problems. So this is a holistic matter, with many variables involved in the final output.

How far emission regulation may transform the friction industry is still to see

one of the main factors that has been driving the development of friction materials is the wear resistance at high temperature. Changing the focus to the low temperature, due to the future emissions homologation standards, may bring changes in formulation styles and raw materials. But also new technologies that are being developed to reduce the brakes emissions may see a commercial future. Vacuum aspiration technology focus capturing the particles, and has been shown to be effective in reducing brake particle mass (PM) emission by 85% and particle number emission by up to 90%. With current average brake PM emissions of 11mg/km this equates to emissions of 1.67mg/km, a third of the most ambitious 5mg/km limit proposed by CLOVE. Other technologies, like the hard coated rotors, focus on eliminating the source of the problem, the particles themselves, through the introduction of a wear resistant coating on top of the gray cast iron of the rotor. This technology is mainly related to the development of the Extra High Speed Laser Cladding coating technology.

but there's no doubt that with the capabilities of two companies, RIMSA and Quartz, Quartz and RIMSA, with many years creating innovative, reliable, adaptable and sustainable solutions for the friction industry, and making Innovation and growth-spirit attitude the axes of our success, at Innovamat we are excited to see how far we are able to contribute in the solution to those challenges. More than ever we have the opportunity to be People Rethinking Solutions.
