Formulating car brake pads | Lapinus, part of ROCKWOOL

Recent research highlights that the formulation of automotive brake pads involves over 500 raw materials, typically blending up to 30 components in a single mix. This complexity is critical for withstanding the extreme conditions that brake pads face during operation.

A key objective in brake pad development is minimizing wear to the extent that a single set could potentially last for the lifespan of the vehicle, which in turn helps mitigate environmental impacts. It's reported that over 90% of PM10 particulate emissions from vehicular traffic arise from non-exhaust sources, with a significant portion attributed to brake wear. Notably, materials like Lapinus mineral fibers are certified as biosoluble, making them environmentally friendly and safe for human exposure.

Urban environments face significant challenges from the shedding of materials such as zinc and copper from brakes and tires. This poses serious health and environmental risks, leading to increased global focus on the raw materials used in friction products. For instance, the copper content in friction materials has been capped at 5% in several U.S. states, while Europe prohibits the use of antimony trisulfide in OE passenger car disc pads.

Short-term solutions like filters and vacuum systems may offer temporary relief, but the long-term strategy must emphasize reduced wear and the exclusive use of non-toxic materials in brake pads. Additionally, manufacturers are developing advanced coatings as well as temperature and chemical treatments designed to enhance durability and reduce wear.
