Used primarily in the production of fluoropolymers and fluoroelastomers, this chemical acts as a processing aid to improve the performance and durability of coatings, seals, and gaskets in harsh environments. It is also employed in the formulation of surfactants and surface treatments where resistance to heat, chemicals, and water is required. Due to its long-chain perfluoro structure, it contributes to oil and water repellency in industrial applications, including firefighting foams and specialty textiles. However, its environmental persistence has led to reduced use in consumer products and increased scrutiny in industrial effluents.
