Ketron™ TX FG PEEK (Food Grade) is an internally lubricated, EU 10/2011 and FDA compliant polyetheretherketone grade that offers improved wear and frictional performance over virgin PEEK. Often favored for food and beverage processing and pharmaceutical applications where extreme performance temperatures, critical tolerances, or low frictional heat are required, Ketron™ TX FG PEEK components extend wear and part life by lowering the coefficient of friction over standard PEEK.
