I will explain the chemical resistance of Teflon, fluoropolymer, PTFE, and PFA.
PTFE (polytetrafluoroethylene) and PFA (perfluoroalkoxy alkane) are types of fluoropolymer that both exhibit excellent chemical resistance. PTFE and PFA are resistant to chemical substances and are stable against acids, alkalis, organic solvents, and corrosive gases. They do not react with most substances and do not corrode or degrade. As a result, they are widely used as chemical containers, piping, gaskets, and sealing materials. PFA has a lower melt viscosity compared to PTFE, making it relatively easy to mold and process. Therefore, it expands the range of applications, especially for coatings that require chemical resistance or for thick film processing. *For more detailed information on chemical resistance, please download the materials or contact us.*

basic information
Fluororesin coating is a functional coating with excellent properties such as: - Non-stick - Water and oil repellency - Heat and cold resistance - Low friction - Chemical resistance - Electrical properties Yoshida SKT has been engaged in fluororesin coating since 1963. In 1968, we signed a licensing agreement with DuPont in the United States. Among industrial fluororesin coatings, only manufacturers certified by Chemours (formerly DuPont) are allowed to process coatings named "Teflon (TM) coating." At Yoshida SKT, we provide coatings that maximize the properties of fluororesin according to our customers' needs. We respond flexibly from one piece to mass production. We propose processing tailored to the application and usage environment, even for parts of machines that exist only in a factory. We can handle everything from fine precision parts to large tanks. We can process a variety of items, from precision parts active in cutting-edge fields to tanks with a depth of 6 meters, using our own equipment.
