Outer diameter φ0.95-30 hollow polytetrafluoroethylene rod

Extruded PTFE Hollow Rod (also known as extruded polytetrafluoroethylene tube or PTFE hollow bar) is produced using state-of-the-art ram extrusion technology with premium virgin PTFE resin. This process involves forcing pre-sintered PTFE through a die to form continuous hollow profiles, resulting in:

• Consistent wall thickness and diameter
• Smooth inner and outer surfaces
• Excellent flexibility in length and dimensions
• High production efficiency for longer runs

Compared to molded PTFE hollow rods, extruded versions excel in applications needing thinner walls, longer lengths, and better flow characteristics, making them ideal for fluid handling and precision tubing.

 Key Advantages 

Outstanding Chemical Inertness

Resists virtually all chemicals, acids, bases, solvents, and corrosives (excluding molten alkali metals and select fluorinated compounds). Perfect for harsh chemical processing.

Extreme Temperature Tolerance

Reliable performance from -180°C to +260°C continuously, with short-term exposure to higher temperatures.

Ultra-Low Friction & Self-Lubrication

Coefficient of friction 0.04–0.06 – minimizes wear, supports lubricant-free operations.

Non-Stick Surface

Low adhesion properties ensure easy cleaning and material release.

 Extrusion Process Benefits 

1. 1. Uniform microstructure for enhanced flexibility
2. 2. Smoother finishes reducing flow resistance
3. 3. Longer continuous lengths without joints
4. 4. Tight tolerances for seamless integration
