What Is PTFE?
Machining of PTFE
PTFE (Polytetrafluoroethylene), widely known under the trade name Teflon®, is a high-performance fluoropolymer recognized for its outstanding chemical resistance, non-stick properties, and extremely low coefficient of friction.
PTFE is one of the most chemically inert materials available and is commonly used in environments where conventional plastics or metals would fail.
Please contact our sales and technical teams to learn about how we can provide high-quality machining PTFE ngineering plastic services at a fair and competitive price.

PTFE vs PEEK: Which High-Performance Plastic Should You Choose?
PTFE (Teflon) and PEEK are both high-performance engineering plastics with excellent chemical resistance and thermal stability, but they serve very different application needs.
| Property | PTFE (Teflon) | PEEK |
|---|---|---|
| Max Service Temperature | 260°C (500°F) | 250°C (480°F) |
| Tensile Strength | 25-30 MPa | 95-100 MPa |
| Hardness | Shore D 50-65 | Shore D 85-90 |
| Friction Coefficient | Extremely Low (0.05-0.10) | Moderate (0.30-0.38) |
| Chemical Resistance | Excellent (inert) | Excellent |
| Wear Resistance | Good | Excellent |
| Water Absorption | Near Zero (0.01%) | Very Low (0.1%) |
| Biocompatibility | USP Class VI | ISO 10993 |
| Machinability | Moderate (soft, prone to deformation) | Good (requires experience) |
| Relative Cost | $$$ | $$$$$ |
| Best For | Seals, gaskets, chemical-resistant liners, electrical insulation, non-stick applications | Medical implants, structural components, semiconductor, aerospace, high-load applications |
Choose PTFE if you need the lowest friction coefficient, complete chemical inertness, or a non-stick surface for seals, gaskets, and liners up to 260°C. Choose PEEK if your application requires high mechanical strength, load-bearing capability, wear resistance, or biocompatibility for medical implants.
