PFA is a co-polymer product of PTFE. The co-monomer perfluoroalkyl vinyl ether interferes in the crystallisability and molecular weight to achieve good mechanical properties and melt processability without sacrificing thermal performance and chemical resistance. These multi-coat systems provide higher continuous use temperatures (260⁰C), have a high dielectric strength, and are considered tougher than PTFE or FEP. PFA is generally considered to be substantially better than TEFLON. Due to its chemical resistance properties, PFA industrial coatings can be used on pumps, tanks, valves, and vessels used in the chemical processing industry. These coatings also provide non-stick properties suitable for industrial bakeware applications. PFA industrial coatings melt and flow during baking to provide nonporous films. These multicoat systems allows for higher continuous use at elevated temperatures (260⁰C), have a high dielectric strength and are considered to be tougher than PTFE.
