PFA Flexible Tubing
Model:KXT PFA1125
PFA (PerFluoroAlkoxy) tubing offers similar properties to PFA Flexible Tubing, but is considered more of a premium resin. PFA is preferred when extended service is required in hostile environments involving chemical, thermal, and mechanical stress
Perfluoroalkoxy PFA Flexible Tubinge FEP Tubing KXT PFA1125
PFA (PerFluoroAlkoxy) tubing offers similar properties to FEP, but is considered more of a premium resin. PFA is preferred when extended service is required in hostile environments involving chemical, thermal, and mechanical stress. PFA tubing offers high melt strength, stability at high
processing temperatures, excellent crack and stress resistance, low coefficient of friction, and more than 10 times the Flex life of FEP. It has high resistance to creep and retention of properties after service at 500°F (260°C), with useful properties at -320°F (95°C). PFA tubing
Advantages
• Non contaminating – ideal for use in semiconductor processing
• Maintains mechanical strength at high temperatures
• PFA has better clarity than FEP or PTFE Tubings
• Working temperature of up to 500º F (260º C)
• Combines attributes of PTFE and FEP
• Higher thermal stability than FEP
• 10 times the flex life of FEP
• Non-flammable
• Flexibility., etc
Application
• Fluid Transfer Devices and Water Processing Systems
• Chemical & Pharmaceutical Manufacturing
• Aerospace &Transportation Technology
• Components & Insulators
• Environmental Sciences
• Food Processing,
• Air Sampling
• Electronics
