Bearing materials without PFAS chemicals
Due to their water, heat and dirt resistance, polyfluoroalkyl substances (PFAS) and polytetrafluoroethylene (PTFE) are key materials in the production of self-lubricating plain bearings in a variety of industries. However, PFAS chemicals degrade slowly, posing risks to both human health and the environment. Addressing these concerns, iglide® JPF is a plain bearing material delivering high wear resistance and durability without the use of PFAS or PTFE (photo). This dry-running, wear-resistant polymer offers comparable friction and wear performance to iglide® J, and its development is a response to growing global regulatory pressures to limit the use of harmful substances in industrial and consumer products. This company has in-house material-development and compounding capabilities that enable it to quickly respond to regulatory changes and offer new solutions that meet market demands. The PTFE-free alternative has equivalent performance, according to the company, and its goal is to transition its standard materials to PTFE-free formulations. — Igus Inc., East Providence, R.I.
