RIMSA, a leader in advanced solutions for friction materials, will participate in AsiaBrake 2025 with a presentation by Dr Carlos Lorenzana, the company’s Director of Innovation. This prominent event in the automotive industry will serve as the stage for RIMSA to showcase its latest research on replacing tin sulphide (SnS) and antimony trisulphide (Sb₂S₃) in brake pads.
The challenges of antimony and tin
The rising prices of antimony and tin, driven by growing demand and geopolitical tensions, have posed significant challenges for the automotive industry. These elements, critical in brake pad manufacturing, present not only an economic challenge but also an environmental one, creating a dual impact on the sustainability of friction materials.
Innovative solutions: Iron-based compounds and synergistic blends
In response to these challenges, a new generation of iron-based sulphide compounds (FZ10, SF50, FE50), specifically designed to efficiently replace traditional sulphides. These products are developed by Innovamat, a joint venture between RIMSA and Quartz, which combines the technical expertise of both companies to deliver innovative and sustainable solutions in friction materials.
These alternatives offer performance that matches or surpasses conventional materials, with the following key benefits:
- Cost efficiency: Iron-based compounds are more affordable than antimony and tin.
- Reduced environmental impact: These compounds are a more sustainable option, aligning with the current demands of the industry.
- Application versatility: Depending on specific needs, different compounds can be selected, all rigorously tested to ensure performance.
Furthermore, RIMSA has developed synergistic blends of chemical products that match or even exceed the performance of antimony trisulphide, with a particular focus on demanding applications such as commercial vehicles operating in high-energy environments.
Tribochemistry: The key to innovation
The development of these solutions is underpinned by a deep understanding of tribochemistry, the science of material behaviour in friction processes. According to Dr Lorenzana, “Tribochemistry enables us to advance the replacement of critical materials like sulphides, optimising both the performance and sustainability of brake pads.”
This approach has allowed RIMSA to identify key interactions between compounds and contact surfaces, achieving formulations that precisely meet the demands of complex applications, such as commercial vehicles, without compromising product quality or durability.
AsiaBrake 2025: A platform for leading change
Dr Carlos Lorenzana’s presentation at AsiaBrake 2025 is yet another example of RIMSA’s ongoing commitment to innovation and sustainability in the friction materials industry. This contribution reflects the company’s strong track record in sharing knowledge and advancing more sustainable and cost-effective solutions, reaffirming its role as a leader in the transition towards a more efficient and responsible future.
