PTFE Rod/Bar Manufacturer
We are a leading manufacturer of PTFE rods, specializing in both extrusion and molding manufacturing methods.
Our PTFE rods are made from virgin PTFE or filled materials (glass fiber, carbon, bronze, and graphite), and they are available in various sizes, shapes, and lengths.
- 100% virgin PTFE
- Filler addition
- Diameter: 10mm - 350mm
- Length: Cut-to-size
- Extruded / Molded
- ISO 9001, FDA, RoHS and ASTM standards
Our PTFE Bar Stock
PTFE Round Bar
- Cylindrical in shape and offer uniformity in diameter.
- Easily machined into custom parts such as seals, bushings, bearings, and gaskets.
PTFE Square Bar
- Equal side lengths and provide excellent support.
- Ideal for machining parts like spacers, blocks, and electrical insulators.
PTFE Rectangular Bar
- Feature a flat shape, offering larger surface areas.
- Cutting into customized parts such as large seals, liners, or structural components.
PTFE Rod Structure
PTFE Solid Rod
- Made entirely of PTFE and are solid throughout.
- Can be easily machined to create custom parts.
- Tends to be stronger and more durable because it is fully solid and can handle higher mechanical stress.
PTFE Hollow Rod
- Have a cylindrical shape with a hollow center.
- Can also be machined, but may require additional fabrication steps.
- May not handle the same mechanical stresses as solid rods due to the hollow core reducing its structural integrity.
PTFE Rod Manufacturing
1. Compression Molding
Molded PTFE rods are created by placing PTFE powder into a mold and then heating it under pressure to form a solid, uniform shape.
PTFE rods made through compression molding have the following features:
- Higher Density
- Smoother Surface Finish
- Higher Strength and Durability
- Larger Diameters Size Availability
- More Expensive
2. Extrusion
Extruded PTFE rods are formed by forcing PTFE resin through a die under high pressure to create a continuous rod, which is then cooled and cut to length.
PTFE rods made through extrusion process have the following features:
- Less dense
- Softer
- Available in smaller diameters
- Less expensive
Filled PTFE Rod
Filled PTFE rods are a variation of the standard PTFE material that is reinforced with additives like glass fiber, carbon, bronze, or graphite to improve its mechanical properties.
Glass Filled
- 15% to 30% glass fibers
- Increased strength & stiffness
- Improved heat resistance
- Reduced creep
Carbon Filled
- 10% to 25% carbon particles
- Enhanced conductivity
- Improved wear resistance
- Lubricating properties
Bronze Filled
- 10% to 30% bronze powder
- Improved wear resistance
- Self-lubricating effect
- Improved thermal conductivity
Graphite Filled
- 5% to 25% graphite particles
- Low friction & wear resistance
- Enhances lubrication properties
- Improved thermal conductivity
