Optimized Flow Rates
Precision melt flow ranges engineered specifically for tubing, lining, molding, and ultra-pure chemical transfer.
Chemical processing equipment operates in some of the most aggressive and unforgiving environments in modern industry.
Aggressive chemicals, elevated temperatures, pressure, mechanical stress and long service requirements can all affect material performance. For this reason, material selection cannot be based on chemical resistance alone.
PFA (Perfluoroalkoxy) is often considered when engineers need a combination of chemical resistance, thermal performance, mechanical reliability, and processability.
Why PFA for Chemical Processing?
PFA is a fully fluorinated thermoplastic fluoropolymer with strong resistance to many chemicals and solvents.
Everflon™ PFA products are designed to provide high chemical resistance while maintaining useful electrical and mechanical properties across a broad temperature range. Everflon specifies service temperatures up to 260°C (500°F), depending on product and application conditions.
This combination makes PFA attractive for components that may be exposed to demanding chemical environments.
Typical Chemical Processing Applications
PFA may be considered for applications across high-reliability fluid management systems:
Chemical Tubing
Pipes
Linings
Valves
Fittings
Pump Components
Fluid-Handling Components
Tanks and Vessels
Chemical Delivery Systems
Molded Components
*The appropriate material and grade depend on the specific application and processing method.
Chemical Resistance Is Not the Only Requirement
Imagine a component exposed to an aggressive chemical at elevated temperature. Chemical resistance is essential. But the component may also need to withstand multiple overlapping operating stresses:
Pressure
Withstanding static hydraulic pressure and intense line surges without expansion or burst failure.
Mechanical Loading
Carrying structural tension, bolt tightening torque, and continuous piping vibration.
Thermal Cycling
Preventing micro-cracking and material fatigue caused by rapid hot-to-cold thermal shock cycles.
Flexing
Ensuring dynamic flexural fatigue endurance for moving diaphragms, bellows, and flexible hoses.
Abrasion & Stress
Resisting abrasive fluid slurries and environmental stress crack formation over long service runs.
Long-Term Creep
Resisting cold flow deformation and seal relaxation under sustained mechanical pressure.
This is why the complete operating environment must be evaluated.
High-Temperature Performance
Temperature can significantly influence polymer performance. As temperature increases, mechanical properties can change, and long-term creep may become an important design consideration.
Everflon™ PFA is designed for demanding thermal environments and provides high-temperature creep resistance. For each application, engineers should evaluate the actual operating temperature, exposure duration and mechanical loading.
Engineered Chemical Tubing & Lining Applications
PFA for Chemical Tubing
Tubing is one of the most important applications for PFA. PFA tubing can be considered when the application requires:
Chemical Resistance
Electrical Insulation
Low Friction
High-Temperature Capability
Flexibility and Toughness
Low Moisture Absorption
Different tubing geometries and production speeds may require different PFA grades.
PFA for Linings
PFA can also be used in lining applications where chemical protection of the underlying structure is required. Potential applications include:
Chemical Vessels
Pipes
Tanks
Process Equipment
Fluid-Handling Systems
High-purity PFA grades can provide additional options when contamination control is important. Everflon™ GC grades are specifically positioned for high-purity chemical fluid handling applications.

Start With the Actual Chemical Environment
When selecting PFA, engineers should identify the complete operating matrix:
Chemical Type
Specific chemicals, acids, bases & solvents
Concentration
Percentage & state phase shifts
Operating Temperature
Baseline, continuous & excursion spikes
Pressure
Static line pressure & surge cycles
Exposure Time
Continuous multi-year service lifespans
Mechanical Stress
Vibration, flexing, bending & tension
Component Geometry
Wall thickness, inner diameters & tolerances
Processing Method
Extrusion, compression or injection molding
Chemical compatibility should always be evaluated against the actual service conditions.
