PFA is superior to PTFE in terms of flexibility particularly when it comes to tubing applications. ... PTFE is slightly more resistant to heat than PFA. PFA is more affected by water absorption and weathering but is superior to PTFE when it comes to salt spray resistance.
What is PFA tubing made of?
PFA tubing is a fluoropolymer tubing, designed to combine the strengths of FEP and PTFE tubing. This product gives the customers the best of both worlds, or in this specific case, the best of both fluoropolymers.Feb 17, 2020
Is PFA a rubber?
EPDM rubber belongs to the thermoset elastomers (rubber) classification, while PFA belongs to the thermoplastics. There are 9 material properties with values for both materials.
What is PFA in tubing?
PFA (perfluoroalkoxy) tubing is a type of fluoropolymer tubing that many industries make wide and diverse use of. We can think of PFA tubing as a combination fluoropolymer that combines the strengths of both PTFE and FEP tubing, allowing users to leverage the attributes of both fluoropolymers.May 8, 2015
Is PFA tubing flexible?
PFA (perfluoroalkoxy) is a tough, flexible fluoropolymer that is used for flexible tubing and fluid processing equipment when chemical resistance, high purity, and low stiffness are required.
Is Teflon tubing flexible?
PTFE tubing is the most flexible of all fluoropolymer tubing offered. ... The smooth surface finish and lowest coefficient of friction & lubricity make the tubing, pipe or rod ideal for bushing or bearing applications. PTFE tubing temperature range is -410°F to 500°F.
