Fluororesin is a plastic material that can be continuously used at temperatures of 260°C. I will explain the reason for this heat resistance.
■Reasons why fluoropolymer (PTFE) excels in heat resistance and cold resistance The molecular structure of PTFE is such that fluorine atoms (F) surround the C-C bonds without any gaps. The breaking of C-C bonds and C-F bonds at high temperatures is one aspect of "PTFE degradation." The C-C bonds are less likely to break because they are protected by the surrounding fluorine atoms (F). The bond strength of C-F bonds within PTFE molecules is significantly greater than that of other atomic bonds. Additionally, the high bond energy of C-F bonds is another reason for its excellent heat and cold resistance. ■Applications utilizing the heat and cold resistance of fluoropolymers In the case of fluoropolymer coatings, for example, baking molds utilize the non-stick properties provided by the coating to prevent baked goods from sticking to the mold. Furthermore, since it also possesses heat resistance, it can be safely used in applications where it is baked in an oven. Additionally, in household irons, the heat plate is coated with fluoropolymer to take advantage of its smoothness and heat-resistant properties. For more details, please click the link or contact us.

basic information
Fluororesin coatings are functional coatings that possess excellent properties such as: - Non-stick - Water and oil repellency - Heat and cold resistance - Low friction - Chemical resistance - Electrical properties Yoshida SKT has been conducting 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 permitted to use the name "Teflon (TM) coating." At Yoshida SKT, we provide coatings that maximize the properties of fluororesin tailored to our customers' objectives. We respond flexibly from single items to mass production. We can propose processing that suits the application and usage environment, even for parts of machines that exist only in one factory. We can perform coatings on everything from fine precision parts to large tanks. Our in-house equipment allows us to process a variety of items, from precision components active in cutting-edge fields to tanks with a depth of 6 meters.
