It withstands friction heat without wearing out and the coating effect lasts!
PBI (Polybenzimidazole) and PI (Polyimide) possess the highest heat resistance among super engineering plastics and are ultra-super engineering plastics that excel in electrical insulation and other properties. At Yoshida SKT, we have developed a technology to apply PBI and PI, which have traditionally been used as plastic molded products, as coatings on the surfaces of metal products and other materials. This coating process allows us to enjoy the excellent functions and properties of super engineering plastics while also gaining advantages in cost and durability that molded products do not offer. *For more details, please refer to the catalog or contact us directly.
