Introduction

Fluoropolymers are the backbone of modern chemical processing equipment. Their unmatched chemical inertness makes them the material of choice for handling aggressive acids, caustics, and solvents. But choosing the wrong fluoropolymer can mean premature failure, costly shutdowns, and safety risks.

This guide compares the four most commonly used fluoropolymers in chemical processing — PTFE, FEP, PFA, and PVDF — across the properties that matter most to procurement engineers and plant managers.

Overview: What Each Material Is Best For

Fluoropolymer Best For Key Advantage Main Limitation PTFE Linings, seals, gaskets, valve components Best chemical resistance of all polymers Cold flow, poor mechanical strength FEP Lined pipes, cable insulation, lab equipment Fully melt-processible, transparent Max temp 200°C, lower mechanical strength PFA Chemical process piping, fittings, vessels Near-PTFE chemistry + melt processible, 260°C rated Higher cost than PTFE PVDF Pumps, membranes, pipe systems Best mechanical strength + chemical resistance combination Attacked by some polar solvents

1. Chemical Resistance Comparison

PTFE — Near-Universal Inertness

PTFE (Polytetrafluoroethylene) is the most chemically inert material known. It is virtually unaffected by:

– All acids including fuming sulfuric acid, hydrofluoric acid, and nitric acid

– All bases including concentrated NaOH and NH₄OH

– Organic solvents including aromatics, ketones, and esters

– Oxidizers including concentrated H₂O₂ and peroxyacids

The only chemicals that attack PTFE:

– Elemental fluorine (above 100°C)

– Chlorine trifluoride (ClF₃)

– Certain molten alkali metals

– Very high temperatures (>300°C) with oxidative atmosphere

PFA — Equal Chemical Resistance, Better Processability

PFA (Perfluoroalkoxy) has virtually identical chemical resistance to PTFE because both are fully fluorinated polymers. The key difference is that PFA can be heat-formed like thermoplastic, making it suitable for weldable pipe systems and injection-molded fittings that PTFE cannot easily produce.

PVDF — Selective Chemical Resistance

PVDF (Polyvinylidene Fluoride) offers excellent resistance to:

– Halogenated solvents (good for chlorinated hydrocarbon processing)

– Acids including HCl, H₂SO₄, HNO₃ (concentrated, at moderate temps)

– Bases

– Salt solutions

PVDF is attacked or degraded by:

– Dimethylformamide (DMF)

– Dimethylacetamide (DMAc)

– Strong bases at high temperatures

– Some ketones and esters

– Concentrated sulfuric acid at elevated temperatures

FEP — Similar to PTFE, Slightly Less Robust

FEP (Fluorinated Ethylene Propylene) has chemical resistance close to PTFE but with slightly more permeability, especially to gases. It is typically used in corrosion-resistant linings for pipes and vessels where full PTFE mechanical performance is not required.

2. Temperature Ratings

Material Continuous Service Temp Short-term Peak Temp Glass Transition (Tg) PTFE 260°C 300°C -20°C PFA 260°C 300°C +5°C FEP 200°C 230°C +30°C PVDF 150°C 175°C -35°C

Key insight: For high-temperature chemical processing (>200°C), only PTFE and PFA are viable choices. PVDF is limited to applications below 150°C continuous.

3. Mechanical Properties

Property PTFE PFA FEP PVDF Tensile Strength 20-35 MPa 25-45 MPa 20-30 MPa 35-55 MPa Flexural Modulus 400-600 MPa 600-700 MPa 500-700 MPa 1,500-2,500 MPa Impact Strength Excellent Excellent Good Good Abrasion Resistance Poor Fair Fair Good Creep (Cold Flow) Significant Moderate Moderate Low UV Resistance Excellent Excellent Excellent Fair

Design implication: If the application involves mechanical loading or pressure (e.g., pipe supports, valve bodies), PVDF’s superior flexural modulus and low creep make it the practical choice over PTFE.

4. Applications by Industry

Chemical Processing & Petrochemical

– PTFE: Gaskets, seals, expansion joints, vessel linings

– PFA: Lined pipe flanges, fittings, sampling systems

– PVDF: Process piping, pump impellers, pressure-rated components

Pharmaceutical & Food Grade

– PFA: Highest purity, ideal for high-purity water systems, bioreactors

– FEP: Transparent tubing, fluid transfer lines

– PTFE: Steam sterilizable components, diaphragm valves

Semiconductor & Electronics

– PFA: Chemical distribution systems (wet bench)

– PTFE: High-purity chemical storage

– PVDF: DI water systems, low-turbidity applications

Battery & EV Manufacturing

– PVDF: Binder for electrode coatings (most widely used)

– PTFE: Battery separator membrane coatings

– PFA: Electrolyte handling systems

5. Cost Comparison (2026)

Material Approximate Price Range Price Trend PTFE (Virgin) $15-30/kg Stable PFA (Virgin) $60-120/kg Slightly increasing FEP $30-60/kg Stable PVDF (Virgin) $20-50/kg Increasing (EV demand)

Note: PVDF prices have increased significantly due to surging demand from the lithium-ion battery industry (as a binder and separator coating). Plan for longer lead times.

6. Supplier Evaluation Checklist

Before placing orders with a fluoropolymer supplier, evaluate:

Material Verification:

– [ ] Material batch certificate (MTR) with traceability to resin manufacturer

– [ ] Test reports for tensile strength, elongation, and hardness per batch

– [ ] Melt flow index (MFI) test to verify molecular weight consistency

– [ ] Specific gravity test to check for filler adulteration

Compliance & Safety:

– [ ] FDA 21 CFR compliant grades for food/pharma applications

– [ ] REACH / RoHS declarations

– [ ] UL94 flame rating for electrical applications

– [ ] ASTM D4894 / D2116 / D3307 compliance as applicable

Supplier Capability:

– [ ] In-house compounding capability (custom compounds for specific chemical environments)

– [ ] Stock availability for common grades (≤4-week lead time preferred)

– [ ] Technical support for material selection consultation

– [ ] Production capacity for large orders (if needed)

Conclusion

For most chemical processing applications:

– Best overall chemical resistance: PTFE (when mechanical loading is not critical)

– Best for pressure-rated piping & fittings: PFA

– Best balance of mechanical strength + chemical resistance: PVDF

– Best for transparency and ease of fabrication: FEP

If budget permits and the application involves high temperatures with aggressive chemicals, PFA is increasingly the preferred choice over PTFE due to its weldability and superior long-term dimensional stability.
