In recent years, per- and polyfluoroalkyl substances (PFAS) have emerged as significant environmental concerns due to their persistent nature and adverse health effects. PFAS, known for their water and grease repelling properties and stability, find wide application in various products like fabrics, cleaning agents, and firefighting foam. Their accumulation in humans, primarily through diet and consumer products, has been linked to health issues such as low birth weight and increased cancer risks. Mounting regulatory pressures have prompted reconsideration of PFAS production.
While small molecule fluorocarbons, including PFAS, are not extensively used in medical devices, they are integral in manufacturing medical grade polymers like polytetrafluoroethylene (PTFE), renowned for its high temperature resistance and chemical inertness. PTFE's versatility makes it indispensable in industries such as semiconductor manufacturing. However, concerns about environmental impact and friction-related issues have prompted the exploration of sustainable alternatives.
Emerging fluorine-free coatings offer promising alternatives to PTFE, addressing environmental concerns without compromising performance. These coatings provide low friction and durability without the environmental drawbacks associated with PFAS. As environmental awareness grows, the development and adoption of such alternatives may mitigate the environmental impact of fluorine-containing chemicals like PTFE.
