Can we ditch antimony and tin in brakes? The quest for sustainable friction
Antimony trisulfide (Sb2S3) and tin sulfide (SnS) have long been essential components in brake pad formulations, contributing to friction stability, wear resistance, and noise reduction. However, the increasing prices of these metal sulfides, coupled with geopolitical uncertainties and supply chain challenges, are driving the brake industry to seek alternative materials. In this blog post, we […]
Bi2S3: a promising solid lubricant for demanding applications
As industries push the boundaries of performance and efficiency, the demand for advanced lubrication solutions has never been greater. Traditional lubricant additives, while effective in many applications, often struggle in extreme environments characterized by high temperatures, extreme pressures, and specialized material requirements. In the search for enhanced lubrication, bismuth sulfide (Bi2S3) has emerged as a […]
Introducing ecoZir Sand: The high-quality zirconium silicate for sintered friction materials
Are you struggling to find a raw material that ensures both high performance and reliability in sintered friction materials? Many manufacturers face challenges in sourcing materials that meet strict requirements for particle size distribution, radioactivity levels, and consistent availability. Without the right material, production inefficiencies, quality issues, and regulatory concerns can arise, leading to increased […]
Fiber Reinforced Concrete: A Revolution in the Construction of Hydraulic Infrastructures
Discover how HRF improves the durability, sustainability and performance of water infrastructure, from large tunnels to smaller pipelines, and how they have influenced the construction of other subway infrastructure. The growing global demand for water and the increasing challenges posed by aging infrastructure require innovative water infrastructure solutions. Fiber-reinforced concrete (HRF), a versatile composite material, […]
What is polyacrilonitrile (PAN)?
Go back Polyacrylonitrile is the most common precursor used to make carbon fiber. Polyacrylonitrile (PAN) is a synthetic resin prepared by polymerization of acrylonitrile. It belongs to the important family of acrylic resins and is a tough and rigid thermoplastic material that, resistant to most solvents and chemicals, burns slowly and has a low permeability […]
Reducing 40% of copper content on existing formulations is at just one test ahead
Go back The copper-free race set on 2021 its first goal. On that point, friction material sold in Washington and California will only allow 5% copper on its composition. Although the seed of this challenge was planted on the mentioned states, this environmental concern has grown up until become into a prevailing assignment for all […]
Bismuth sulfides the new contenders against strong LME dependent metals?
Go back Spoiler, they are! Despite the current circumstances, the increase in the production volume of metallic Bi has divided its base price by 3 and has stabilized at that level, making its use viable for the friction industry. The industry has evolved, and so we did! Since we were the rookies of the friction […]
Bismuth-based products not as rare as it is thought. Why now is the time?
Go back In your opinion, which are the metals that are mostly used on friction materials nowadays? Imagine we had the opportunity to do a massive survey asking this question to friction industry formulators. They’d surely answer iron in first place, probably followed by copper, zinc, tin, maybe aluminium…But presumably not bismuth! It sounds quite […]
