PEEK is a semi-crystalline thermoplastic suited for high temperature and high pressure. Stronger than most engineering plastics, PEEK is known for being able to retain its mechanical properties at elevated temperatures. PEEK is also able to perform in a broad spectrum of chemical environments. PEEK applications include o-ring backups, secondary seals, valve seats, and electrical insulators. Our high quality, competitively priced PEEK is readily available to fit your needs. Please use our website or call 713-722-0020 to begin the quote and ordering process.
