Company profile
researched Aug 2026PI Advanced Materials (PI첨단소재), operating the pimaterials.com website, is a South Korean specialty chemicals company producing polyimide (PI) advanced materials. Its PI Varnish and PI Powder/Mold business supplies material solutions built on dedicated powder production facilities for advanced-industry materials, in-house powder design technology and R&D capability, and process and quality control systems.
The company's Zenimid brand covers PI powder and molded (formed) products. Stated material characteristics include usability from cryogenic temperatures near absolute zero up to approximately 400°C, self-lubrication and wear resistance under high-friction conditions, high elongation permitting machining to fine tolerances, and dimensional stability under high temperature and pressure. Product grades listed include Zenimid PI Natural Grade "MP" (semi-finished products such as sheet, mainly machined into customized parts such as rollers, guide pins and vacuum pads), Zenimid PI ESD Grade "ME" (electrostatic-dissipative, surface resistance 10^6–10^9, used for rollers, tools and handling equipment to prevent electrostatic damage), and Zenimid PI Powder for Filler "PW" (used in compound fillers, diamond wheels and fibers).
The company describes three application areas: display, where Zenimid PI Mold parts are qualified and supplied for mass production to major display makers for etching, deposition and heat-treatment processes; semiconductors, where the material is used in front- and back-end components such as etch rings, vacuum pads and test sockets requiring etch resistance, chemical resistance and dimensional stability; and new businesses including electric vehicles, aerospace and defense equipment, where the material is positioned as a super engineering plastic offering light weight together with wear resistance, insulation and heat resistance.
Business model
The company manufactures and supplies polyimide-based advanced materials — PI varnish, PI powder and molded PI products — to industrial customers, which use them as process components and raw materials in their own manufacturing. Products are supplied in semi-finished forms such as sheets for customer machining, as well as powder sold as a filler input, with a stated emphasis on stable supply of qualified material and development of new grades ahead of market demand.
