At Aetna Plastics, we provide high-performance plastics engineered for the most demanding industrial environments. PTFE (polytetrafluoroethylene), also known by the brand name Teflon, is a fluoropolymer valued for its near-universal chemical resistance, extreme temperature capability, and the lowest coefficient of friction of any solid material. When your application involves aggressive chemicals, high heat, or critical sealing requirements, PTFE is the material of choice.
What is PTFE?
At Aetna Plastics, we provide high-performance plastics engineered for the most demanding industrial environments. PTFE (polytetrafluoroethylene), also known by the brand name Teflon, is a fluoropolymer valued for its near-universal chemical resistance, extreme temperature capability, and the lowest coefficient of friction of any solid material. When your application involves aggressive chemicals, high heat, or critical sealing requirements, PTFE is the material of choice.
Why Choose PTFE ?
PTFE stands apart from other engineering plastics for its combination of chemical inertness, thermal stability, and surface properties.
Key Properties:
- Near-Universal Chemical Resistance: Virtually inert to all industrial chemicals, acids, caustics, and solvents
- Extreme Temperature Capability: Performs reliably from -328°F (-200°C) to +500°F (260°C) continuous service
- Lowest Coefficient of Friction: The slipperiest solid material available, ideal for sealing, sliding, and non-stick surfaces
- Excellent Electrical Insulation: Outstanding dielectric properties across a wide range of temperatures and frequencies
- Non-Stick Surface: Resists adhesion of particles, contaminants, and process media
- Weatherability: Exceptional UV and weather resistance for long-term outdoor exposure
- FDA Compliant Grades: Available for food processing and pharmaceutical applications
Standard Shapes and Forms
Aetna Plastics offers PTFE in a variety of stock shapes to support both standard and custom fabrication:
- Sheet: Molded and skived sheets in a range of thicknesses for gaskets, liners, and wear surfaces
- Rod: Molded and extruded rod in a broad selection of diameters for seals, bushings, and turned parts
- Tube: Standard and custom sizes for sleeves, spacers, and pipe linings
- Film and Tape: Thin-gauge options for wrapping, insulation, and surface protection
- Machined Parts: CNC-fabricated components based on your drawings or specifications
Common Applications for PTFE
PTFE’s chemical inertness, thermal stability, and low friction make it indispensable across a wide range of industries:
- Chemical Processing: Gaskets, seals, valve seats, and pipe linings for handling aggressive acids, caustics, and solvents
- Water & Wastewater Treatment: Wear-resistant components, seals, and linings for corrosive treatment environments
- Pollution Control Equipment: Duct linings, scrubber components, and sealing systems exposed to harsh chemical exhaust
- Food Processing: Non-stick surfaces, conveyor components, and seals in FDA-compliant applications
- Electrical & Electronics: Insulators, spacers, terminal blocks, and wire coatings requiring high dielectric strength
- Fluid Handling: Pump components, O-rings, piston rings, and bearing surfaces in high-temperature or corrosive service
- General Manufacturing & OEM: Slide plates, wear strips, and non-stick tooling surfaces
Grades and Colors
PTFE is typically available in natural (white). Filled grades may appear gray, black, or brown depending on the filler material. Common formulations include:
- Virgin (Unfilled) PTFE: The purest form, offering the highest chemical resistance, lowest friction, and best electrical insulation properties
- Glass-Filled PTFE: Improved wear resistance, reduced creep, and better dimensional stability under load
- Carbon-Filled PTFE: Enhanced compressive strength and thermal conductivity for high-load and high-speed applications
- Bronze-Filled PTFE: Superior load-bearing capacity and thermal conductivity for heavy-duty bearing and piston ring applications
- Graphite-Filled PTFE: Lower friction and improved wear in dynamic sealing applications
Fabrication and Machining Support
PTFE can be machined to precise tolerances with proper tooling and technique. Because PTFE has low thermal conductivity and a tendency to creep under sustained load, experienced handling is essential. Aetna Plastics provides:
- Cut-to-Size Blanks & Kitting: Stock material prepared to your specifications
- CNC Milling, Turning & Routing: Precision parts machined using carbide tooling for clean cuts and tight tolerances
- Design-Assist: Guidance on grade selection, creep considerations, and optimizing your design for PTFE’s unique properties
