PFAS are synthetic chemicals that have been around since the 1940s and are still widely used in manufacturing and even found in our water. This article delves into four main types of companies that utilize PFAS in their production processes and sheds light on the benefits, challenges, and ongoing debates surrounding their use.
Many industries, from electronics and semiconductors to cosmetics and personal care products, employ PFAS. Textile and Apparel Companies use PFAS to make fabrics more water-repellent, stain-resistant, and durable. Firefighting foam manufacturers have been significant users of PFAS, especially in making aqueous film-forming foams (AFFF). These foams are essential for extinguishing high-intensity fires involving flammable liquids like oil and gasoline.
The nonstick cookware industry has long relied on PFAS, particularly polytetrafluoroethylene (PTFE), known as Teflon. PTFE鈥檚 nonstick properties are highly desirable, making cooking easier and reducing the need for oil. Despite concerns over harmful effects, some brands continue to use PFAS.
Finally, PFAS are widely used in aerospace and automotive industries because of their excellent resistance to heat, chemicals, and wear. In aerospace, PFAS are used in fuel and hydraulic systems to withstand extreme temperatures and pressures, ensuring reliable performance and safety.
PFAS exposure has been linked to several types of cancer, including kidney, testicular, and liver cancer. Research suggests that PFAS can disrupt hormonal and cellular functions, potentially contributing to the development of these cancers. Balancing the benefits of PFAS with the need for environmental and public health protection remains a crucial challenge.
