PTFE Rod.

Extruded homogeneous PTFE rod, carrying the base properties intact: −200 to +260 °C, broad chemical resistance and the lowest friction (μ 0.04). Ø5–300 mm standard, cut to the length you order. Widely used as machining stock for seals, bushings, liners, seats and electrical insulation.

— PTFE Grades ／ 3 Formulations

Grades

/ 01

Virgin PTFE— unfilled fluoropolymer

μ 0.04LOWEST FRICTION

Moulded from PTFE alone, with no filler. Lowest friction, best chemical stability, and the full −200 to +260 °C range. For medical, food and semiconductor wet processes where purity matters.

/ 02

Modified PTFE— low-creep modified PTFE

−50%CREEP vs. VIRGIN

Copolymerisation lowers crystallinity, improving creep resistance and cold flow. For precision seals and sealed bushings that must hold up under long-term load.

/ 03

Filled PTFE— filled grades · 3 types

≤ 45MPa · HIGH LOAD

Choose the filler according to load, wear and heat transfer requirements.

Glass FilledHeavy load, low creep. Best for valve seats and bushings.
Bronze FilledBetter wear resistance and heat transfer. Industrial bearings and slides.
Carbon FilledWear resistant and electrically conductive. Semiconductor and anti-static parts.

— Applications

Applications

/ SEALING

Seals & Gaskets
