Material Overview

Why Is PTFE Used in Industrial Applications?

PTFE is a fluoropolymer valued for its chemical resistance, low friction, electrical properties and wide operating-temperature range. Its suitability depends on the specific grade and application.

Key Material Characteristics

Excellent resistance to many chemicals and corrosive media.
Very low coefficient of friction in many sliding applications.
Useful electrical insulating properties.
Low water absorption.
Good performance across a wide temperature range.
Non-stick surface characteristics.

Virgin and Filled PTFE

Virgin PTFE is commonly selected for chemical resistance, electrical insulation and low-friction applications. Filled PTFE compounds may incorporate glass fiber, carbon, graphite, bronze or other additives to modify properties such as wear resistance, stiffness, creep behavior and dimensional stability.

The best formulation depends on operating conditions, mating materials, load, speed and chemical exposure. Filled PTFE is not automatically suitable for every chemical or sealing application.

Typical Material Properties

PTFE Property Overview

The following figures are general reference values for unfilled virgin PTFE. They are not guaranteed specifications for every grade, filled compound or finished product.

Property	Typical Reference Value	Important Notes
Continuous Service Temperature	Approximately -200°C to +260°C	Application, grade, load and exposure conditions matter.
Coefficient of Friction	Often around 0.04–0.10	Highly dependent on test conditions, pressure, speed and mating surface.
Tensile Strength	Approximately 20–35 MPa	Varies with grade, processing and test method.
Density	Approximately 2.1–2.3 g/cm³	Filled PTFE compounds have different densities.
Chemical Resistance	Excellent against many chemicals	Check specific media, temperature and operating conditions.
Water Absorption	Very low	Useful for applications requiring low moisture uptake.

Reference values are indicative only. For material selection and engineering design, request the technical data sheet for the specific PTFE grade. Filled and modified compounds can have significantly different properties.

Material Selection

How to Select the Right PTFE Material

Selecting PTFE is not only about choosing a shape or thickness. The formulation should match the operating conditions and performance requirements of the finished component.

Consider the Operating Conditions

Operating and peak temperatures.
Chemical media and concentration.
Pressure, load and sliding speed.
Required friction and wear performance.
Electrical insulation or conductivity requirements.
Dimensional stability and creep requirements.

Choose the Appropriate Product Form

Sheet: Flat components, gaskets and machined plates.
Rod: Bushings, sleeves and cylindrical parts.
Powder: Coatings, modification and compounding applications.
Film: Thin insulation and release applications.
CNC Parts: Components manufactured to drawings.

Frequently Asked Questions

PTFE Materials – Common Questions

Basic information to help purchasing teams and engineers evaluate PTFE materials.

1. What is PTFE material?

PTFE stands for polytetrafluoroethylene. It is a fluoropolymer known for excellent chemical resistance, low friction, non-stick properties and useful electrical insulation.

2. What is the temperature range of PTFE?

Unfilled PTFE is commonly referenced for continuous service from approximately -200°C to +260°C. The practical limit depends on load, pressure, chemical exposure, product form and the specific grade.

3. What is the difference between virgin and filled PTFE?

Virgin PTFE is unfilled and is often selected for chemical resistance, electrical insulation and low friction. Filled PTFE incorporates additives such as glass fiber, carbon, graphite or bronze to modify mechanical, wear or dimensional properties. The right choice depends on the application.

4. Can PTFE be CNC machined?

Yes. PTFE can be turned, milled, drilled and machined into custom components. However, its relatively high thermal expansion and tendency to deform under load require careful machining and inspection. Achievable tolerances depend on component geometry and dimensions.

5. Is PTFE resistant to all chemicals?

PTFE has excellent resistance to a very wide range of chemicals, but it should not be described as universally inert under every condition. Certain highly reactive substances and extreme operating environments require specific compatibility checks before material selection.

6. What PTFE product forms can Teda Plastics discuss?

Our PTFE product categories include sheets, rods, powders, films and CNC machined components. Specific grades, dimensions, production feasibility and availability should be confirmed according to your requirements.
