Intro

PFA (Perfluoroalkoxy) PTFE (Polytetrafluoroethylene)
PFA Tubing Working Temperature: 500°F (260°C) Working Temperature: 500°F (260°C)
Color: Clear with light blue or tint
Color: Opaque to translucent
A
• High purity resins available • Chemically inert
• Low permeation resins available • Lowest coefficient of friction
• Use when you need the temperature range of PTFE • Superior dielectric strength
and the clarity of FEP • Exceptional heat resistance
• Exceptional heat resistance • Self extinguishing
• Self extinguishing • Nonwetting
• Nonwetting • Excellent flexlife
FEP Tubing • Good flexlife • Laser markable
B

High Purity PFA (Perfluoroalkoxy) PVDF (Polyvinylidene Fluoride)
Working Temperature: 500°F (260°C) Working Temperature: 265°F (130°C)
Color: Clear with light blue or tint Color: Varies
See characteristics of PFA with these additional features:
PTFE Tubing • Lowest level of extractables • Very good chemical resistance
Excellent resistance to creep and fatigue
•
C • Highest molecular weight available • UV Resistant
•
Withstands corrosive surfactants for longer periods
Weldable
•
of time • Exceptional corrosion resistance for chlorine,
• Higher flow fluorine, or bromine environments
• Higher purity
PVDF Tubing

D FEP (Fluorinated Ethylene Propylene) ETFE (Ethylene Tetrafluoroethylene)
Working Temperature: 400°F (204°C) Working Temperature: 302°F (150°C)
Color: Clear Color: Clear

• Excellent chemical resistance • Best abrasion resistance
• Nonwetting • Chemically inert
• Weldable • Excellent tear resistance
Tubes can be sealed by melting
Low permeability
•
•
ETFE Tubing • Long continuous lengths • Superior impact strength to PTFE
E • Low refractive index • Excellent for cryognic applications
•
Improved clarity over PFA
• Lower cost alternative to PFA
