Universal Chemical Resistance of PTFE Fluoropolymer

PTFE plastic exhibits complete inertness to virtually all industrial chemicals, acids, bases, and solvents. This fluorocarbon polymer withstands concentrated sulfuric acid, hydrochloric acid, nitric acid, and aggressive organic solvents without degradation. Only molten alkali metals and elemental fluorine at high temperatures affect PTFE, making it the ultimate chemical-resistant plastic for corrosive environments, chemical processing equipment, and laboratory applications.

• Resistant to all acids and bases except molten alkalis
• Inert to organic solvents and hydrocarbons
• Zero moisture absorption (<0.01%)
• Non-contaminating for high-purity applications

Extreme Temperature Performance of PTFE Teflon Material

Continuous service temperature from -200°C to +260°C makes PTFE ideal for cryogenic seals and high-temperature gaskets. The material maintains mechanical properties across this entire range, with a melting point of 327°C. PTFE's thermal stability exceeds most thermoplastics, providing reliable performance in thermal cycling applications, heat exchangers, and temperature-critical sealing systems.

• Cryogenic performance to -200°C without embrittlement
• Heat deflection temperature: 55°C at 0.45 MPa
• Thermal conductivity: 0.25 W/(K·M)
• Coefficient of linear thermal expansion: 100-160 × 10⁻⁶/K

Low Friction PTFE: Self-Lubricating Non-Stick Properties

With a dynamic coefficient of friction of 0.04 - the lowest among engineering plastics - PTFE eliminates stick-slip behavior in sliding applications. This self-lubricating fluoropolymer requires no external lubrication for bearings, bushings, and wear components. PTFE's non-stick surface prevents material adhesion in conveyor systems, release applications, and anti-fouling coatings.

• Static coefficient of friction: 0.04-0.10
• No stick-slip at any sliding speed
• Maintenance-free bearing material
• Release properties for mold applications

Electrical Insulation Properties of PTFE Plastic

Superior dielectric properties make PTFE the preferred insulation material for high-frequency applications, coaxial cables, and electronic components. With a dielectric constant of 2.1 and dielectric strength of 60 kV/mm, PTFE maintains consistent electrical properties across wide temperature and frequency ranges.

• Volume resistivity: >10¹⁸ Ω·cm
• Surface resistivity: >10¹⁶ Ω
• Arc resistance: >300 seconds
• Dissipation factor: 0.0002 at 1MHz

What is the difference between PTFE and Teflon materials?

PTFE (Polytetrafluoroethylene) is the generic chemical name for the fluoropolymer material, while Teflon® is a registered trademark brand name. All Teflon is PTFE, but not all PTFE is branded as Teflon. The material properties and performance are identical - both offer the same chemical resistance, low friction coefficient, and temperature stability. We supply high-quality PTFE materials that meet or exceed industry standards.

How to machine PTFE plastic materials without deformation?

Machining PTFE requires specialized techniques due to its soft, flexible nature. Use sharp carbide or polycrystalline diamond (PCD) tools with positive rake angles. Maintain high cutting speeds (200-300 m/min) with light feeds to prevent material deformation. Coolants help dissipate heat and improve chip evacuation. Support thin sections to prevent flexing, and consider stress-relieving annealing for tight-tolerance parts.

What are filled PTFE compounds and their applications?

Filled PTFE compounds contain additives to enhance specific properties. Glass-filled PTFE (15-25% glass fiber) improves wear resistance and reduces creep for bearing applications. Carbon-filled PTFE (25% carbon) provides electrical conductivity and higher compressive strength. Bronze-filled PTFE (40-60% bronze) offers superior thermal conductivity for heat dissipation. Graphite-filled PTFE combines self-lubrication with moderate conductivity for dynamic seals.

Can PTFE be bonded or glued to other materials?

Virgin PTFE cannot be bonded with conventional adhesives due to its non-stick properties. However, surface treatment using sodium naphthalene etching or plasma treatment creates a bondable surface. Etched PTFE can be bonded to metals, plastics, and elastomers using epoxy, silicone, or specialized fluoropolymer adhesives. Mechanical fastening or encapsulation often provides more reliable attachment for critical applications.

What is the minimum order quantity for custom PTFE machined parts?

We accommodate orders from single prototype pieces to high-volume production runs. No minimum order quantity restrictions apply for custom PTFE machining. Whether you need one specialized PTFE gasket or thousands of precision bearings, our flexible manufacturing capabilities support your requirements. Volume pricing available for larger quantities.

How to select between virgin PTFE vs modified PTFE grades?

Virgin PTFE offers maximum chemical resistance and purity for food, pharmaceutical, and semiconductor applications. Modified PTFE provides improved mechanical properties - choose glass-filled for wear resistance, carbon-filled for electrical conductivity, or bronze-filled for thermal management. Consider operating temperature, load conditions, chemical exposure, and regulatory requirements. Contact our engineers at beeplastic@beeplastic.com for material selection guidance.

What tolerances can be achieved when machining PTFE components?

Our CNC machining achieves tolerances of ±0.03mm (±0.0012") for most PTFE components. Tighter tolerances to ±0.01mm possible for critical features with proper fixturing and temperature control. Factors affecting tolerance include part geometry, PTFE grade, feature size, and aspect ratio. Thermal expansion considerations important for tight-tolerance assemblies operating across temperature ranges.
