ITRI: Tin Sulphides in Brake Pads
Description
Brake pads are complex mixtures containing proprietary blends of substances designed to achieve maximum braking performance without degradation, squealing and other problems. Antimony trisulphide (Sb2S3) has been used extensively as a solid lubricant in friction materials such as brake pads for many years, although recent health and safety concerns for industry workers, combined with environmental issues relating to highway pollution, have driven the demand for safer, non-toxic alternatives, especially in Europe and North America.
