For tough chemical applications Kynar Flex® PVDF is a lighter weight and affordable alternative to fully fluorinated polymers. The wide range of available Kynar Flex® resins provide engineers the ability to design around requirements of flexibility, heat resistance, permeation resistance, and chemical resistance.
Tubing installations based on Kynar Flex® PVDF are used in a variety of industries including: chlor-alkali, petrochemical, marine, biopharmaceutical, food, and semi-conductor.

Note1: The above Kynar® component temperature, pressure and sizing data are compiled from industry data and are for illustrative purposes only. The actual temperature and pressure ratings of your system, as well as its resistance to chemical attack, are dependent on many environmental factors. Higher operating temperatures will reduce the Kynar® system's maximum operating pressure; higher operating pressures will reduce the system's maximum operating temperature. Higher operating pressures or temperatures may also require increased component wall thickness. Consult your Kynar® component supplier about your system's operating parameters before purchasing a Kynar® system.
Note 2: Kynar® componetns can withstand continuous temperatures as low as -30°C (-22°F) under certain conditions. Please contact your Kynar® component supplier with specific information about your application to determine the lowest recommended operating temperature of your Kynar® system.
