PTFE vs PEEK: Which Material is More Suitable for Your Application?

PTFE vs PEEK: Which Material is More Suitable for Your Application?

In the selection of high-performance engineering plastics, PTFE (Polytetrafluoroethylene) and PEEK (Polyether ether ketone) are two frequently mentioned options. Both offer excellent chemical resistance and high-temperature performance,

1. Material Property Comparison

| Property | PTFE | PEEK |
|——|——|——|
| Chemical Structure | Perfluorocarbon polymer (-CF2-CF2-) | Semi-aromatic crystalline thermoplastic |
| Density (g/cm³) | 2.14-2.20 | 1.30-1.32 |
| Melting Point (°C) | 327 | 343 |
| Continuous Use Temperature (°C) | -200 to +260 | -60 to +250 |
| Short-term Temperature Resistance (°C) | 300 | 300 |
| Flame Rating | UL94 V-0 | UL94 V-0 |
| Water Absorption (%) | <0.01 | 0.1-0.5 | | Wear Resistance | Poor | Excellent |

2. Performance Parameter Comparison

2.1 Mechanical Properties

| Performance Indicator | PTFE | PEEK | Test Standard |
|———|——|——|———|
| Tensile Strength (MPa) | 20-35 | 90-110 | ASTM D638 |
| Tensile Modulus (GPa) | 0.4-0.55 | 3.6-4.1 | ASTM D638 |
| Elongation at Break (%) | 200-400 | 20-50 | ASTM D638 |
| Flexural Strength (MPa) | No yield point | 150-170 | ASTM D790 |
| Flexural Modulus (GPa) | 0.5-0.7 | 3.7-4.0 | ASTM D790 |
| Impact Strength (kJ/m²) | Unnotched, unbreakable | 40-60 | ASTM D256 |
| Hardness (Shore D) | 50-65 | 85-90 | ASTM D2240 |

Key Findings:

PEEK’s mechanical strength is 3-4 times that of PTFE
PTFE has better toughness, with elongation at break 5-10 times that of PEEK
PEEK has higher rigidity, more suitable for load-bearing structural parts

2.2 Thermal Properties

| Performance Indicator | PTFE | PEEK | Test Standard |
|———|——|——|———|
| Heat Deflection Temperature (°C, 1.8MPa) | 55 | 315 | ASTM D648 |
| Vicat Softening Point (°C) | 110 | 380 | ASTM D1525 |
| Coefficient of Thermal Expansion (10⁻⁵/K) | 10-12 | 4.7-5.0 | ASTM E831 |
| Thermal Conductivity (W/m·K) | 0.25 | 0.29 | ASTM E1461 |

Key Findings:

PEEK’s heat deflection temperature is much higher than PTFE, suitable for high-temperature load-bearing

PTFE has poor thermal conductivity, – PEEK can bear loads long-term below 250°C, while PTFE is only suitable for low-load high-temperature environments

2.3 Chemical Resistance

| Chemical Substance | PTFE | PEEK | Remarks |
|———|——|——|——|
| Strong Acids (concentrated sulfuric, nitric) | Excellent | Good | PTFE inert |
| Strong Alkalis (NaOH 50%) | Excellent | Excellent | Both corrosion-resistant |
| Organic Solvents | Excellent | Excellent | Except a few strong polar solvents |
| Ketones (acetone, DMF) | Excellent | Fair | PEEK may be attacked above 80°C |
| Automotive Fuel | Excellent | Excellent | Both applicable |
| Hydraulic Oil | Excellent | Excellent | Long-term stable |

Key Findings:

PTFE is inert to almost all chemicals, known as “plastic king”

PEEK’s chemical resistance is slightly inferior to PTFE, – In strong polar solvents and at high temperatures, PEEK’s chemical resistance needs careful evaluation

2.4 Friction and Wear Properties

| Performance Indicator | PTFE | PEEK | Test Standard |
|———|——|——|———|
| Coefficient of Friction (vs. steel) | 0.05-0.10 | 0.30-0.45 | ASTM D1894 |
| Wear Rate (mm³/N·m) | 10⁻³ – 10⁻⁴ | 10⁻⁶ – 10⁻⁷ | ASTM D1044 |
| PV Limit (MPa·m/s) | 0.04 | 5-10 | – |

Key Findings:

PTFE has extremely low friction coefficient, – PEEK has excellent wear resistance, with PV limit values 100 times or more that of PTFE

In practical applications, PTFE is often filled and modified (e.g., with bronze powder, graphite) to improve wear resistance

3. Application Scenario Analysis

Cryogenic applications (-200°C)

Requirements for extremely low friction coefficient (e.g., self-lubricating bearings)

High purity and biocompatibility requirements

3.2 Typical PEEK Applications

Aerospace: Aircraft interior parts, structural brackets, cable sheaths

Automotive Industry: Gears, bearings, seal rings, turbocharger parts

Electronics & Semiconductor: Wafer carriers, chip trays, vacuum pens

Oil & Gas: Downhole tools, valve parts, connectors

Medical Implants: Spinal fusion cages, bone plates, artificial joints (PEEK-CF)

| Typical Product Price (RMB/kg) | 80-150 | 400-800 | 1:5-5.3 |
| Processing Cost | Medium (molding, sintering) | Higher (injection molding requires high-temp equipment) | – |

4.2 Life Cycle Cost Analysis

Although PEEK’s initial cost is 5 times that of PTFE, in the following scenarios the life cycle cost is lower:

High-load wear parts: PEEK service life is 10-50 times that of PTFE, significantly reducing replacement frequency

Precision structural parts: PEEK can be injection molded, suitable for mass production, with unit cost amortized

Maintenance-free design: PEEK’s wear resistance and fatigue performance can reduce maintenance costs

Case Study:
A chemical pump mechanical seal: PTFE seal ring price 500 RMB, service life 3 months; PEEK seal ring price 2500 RMB, service life 2 years. Life cycle cost: PTFE is 4000 RMB/year, PEEK is 1250 RMB/year, saving 69%.

4.3 Processing and Forming Comparison

| Forming Process | PTFE | PEEK | Applicability |
|———|——|——|——–|
| Injection Molding | Not applicable (requires sintering) | Excellent (340-380°C) | PEEK suitable for mass production |
| Compression Molding & Sintering | Primary process | Not applicable | PTFE suitable for small batches |
| Extrusion | Can extrude pipes, rods | Excellent | Both applicable |
| Machining | Easy to stick to tools, requires special tools | Good | PEEK more suitable for precision machining |
| Welding | Can be hot air welded | Can be laser welded | PEEK welding strength higher |
