Chlorotrifluoroethylene (CTFE) and polychlorotrifluoroethylene (PCTFE) are very similar materials and frequently referred to by brand names such as Kel-F, Neoflon, Aclar, and Chemfluour 767. CTFE and PCTFE are simply the generic names that reflect the chemical make-up of these materials.
PCTFE and CTFE differ from other common fluoropolymers as they replace a fluorine atom with a chlorine atom. This small change offers multiple advantages over similar materials in specific applications.
CTFE/PCTFE may be confused with other fluoropolymers such as PTFE—better known as Teflon—but the differences in the materials are quite notable. While there may be some overlap, it should be noted that CTFE/PCTFE and Teflon are each ideal for different purposes.
Choosing CTFE or PCTFE during manufacturing may be a beneficial choice for many designs. Both offer excellent stress-crack resistance and high mechanical strength. CTFE and PCTFE are frequently utilized in cryogenic valve seats, high-pressure gas seats and deals, and various electrical components. A low rate of moisture absorption ensures that CTFE/PCTFE products will maintain beneficial electrical properties even in the face of high humidity—a property that is largely unique among competitive materials.
CTFE and PCTFE offer a wide range of benefits, such as:
CTFE and PCTFE see use in a wide variety of industries. The material is non-flammable, chemical resistant, possesses near-zero moisture absorption, and boasts superior electrical capabilities over other thermoplastic fluoropolymers such as PTFE (Teflon). Common applications of CTFE/PCTFE include:
CTFE and PCTFE are frequently utilized in the fabrication of:

Kel-F® is a registered tradename of 3M. In 1996, 3M discontinued manufacturing of Kel-F. Currently, all PCTFE resin is manufactured by Daikin under the tradename of Neoflon® or by Allied Signal under the tradename of Aclon®. Kel-F is still the most commonly used tradename used to describe PCTFE.
