Clear FEP Tube Used For Fluid Control System
Specification Range
FEP tubing is known for its gas and vapor permeability properties and excellent UV transmission ratings. While very similar in composition to PTFE, there are a few notable differences. FEP has a lower heat shrink temperature and is more clear and flexible than PTFE.
FEP tube is made from FEP resin and prepared by the technology of extrusion. It can be used at the temperature range of -80℃~ 200℃.
FEP tube and PTFE tube are similar in their material properties. The main difference between PTFE tube and FEP tube is the maximum operating temperature and the colour.
FEP tube is a nice alternative to PTFE teflon tubing and PFA tubing that exhibits many similar properties and can be used for most chemicals.
