This article explains the types and characteristics of heat-resistant plastic materials.
High-heat-resistant plastics are materials that possess characteristics suitable for use in high-temperature environments. These plastics generally have high melting points, excellent heat resistance, and chemical stability. ■ Polyimide (PI) Polyimide has very high heat resistance and can be used in environments up to 300°C. It is utilized in electronics, aerospace, and the automotive industry, particularly in situations where durability under high-temperature conditions and harsh environments is required. ■ Polyetheretherketone (PEEK) With a high heat resistance of 260°C, PEEK also offers chemical resistance and wear resistance, making it suitable for use in aerospace, medical, and energy industries. ■ Polyphenylene sulfide (PPS) PPS has high heat resistance and chemical resistance at 220°C and is used in the automotive industry, electronics, and industrial machinery. Fiber-reinforced types of PPS also have high wear resistance, making them suitable for mechanical parts. ■ Polytetrafluoroethylene (PTFE) PTFE has high heat resistance of 260°C, exhibits self-lubricating and non-stick properties, and has high chemical resistance, making it chemically stable. It is used in semiconductors, chemicals, medical applications, aerospace, and the automotive industry.
basic information
■Reasons why fluoropolymer (PTFE) excels in heat resistance and cold resistance The molecular structure of PTFE is such that fluorine atoms (F) completely surround the C-C bonds. The breaking of C-C 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 bonds between other atoms. 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 they also possess heat resistance, they can be safely used in applications where they are baked in an oven. Additionally, in household irons, the heat plates are coated with fluoropolymer to take advantage of their smoothness and heat-resistant properties.

Applications/Examples of results
Fluororesin coating is a functional coating that possesses 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 use the name "Teflon (TM) coating." At Yoshida SKT, we provide coatings that maximize the properties of fluororesin according to our customers' needs. We flexibly accommodate from one piece to mass production. We can propose processing tailored to the application and usage environment, even for parts of machines that exist only in one factory. We can handle everything from fine precision parts to large tanks. We can process a variety of items, from precision components active in cutting-edge fields to tanks with a depth of 6 meters, using our own equipment.
