PTFE seals—commonly referred to by its brand name, Teflon—are a family of sealing solutions utilizing Teflon and Teflon filled variant materials to meet demanding application requirements. Teflon has almost universal chemical resistance, the lowest coefficient of friction of any known solid material, and wide working temperature range. Considering these properties, Teflon is an excellent choice in material for high-performance seals.
PTFE has outstanding properties that can withstand aggressive chemicals, high temperatures, and tough operating conditions. Here are some key material properties of PTFE:
