Product Description
Molded PTFE Rods – High‑Purity, Chemically Inert Rod Stock for Precision Components
Kaxite Sealing is a leading China-based manufacturer and supplier of molded PTFE rods – high‑quality rod stock produced from 100% virgin PTFE resin through advanced compression molding or ram extrusion processes. Available in a wide range of diameters and lengths, our PTFE rods offer exceptional chemical resistance, continuous service from -200°C to +260°C, outstanding dielectric properties, and a low coefficient of friction. They are the material of choice for machining custom gaskets, seals, bearings, electrical insulators, and medical components. Kaxite also supplies filled PTFE rods (glass, carbon, graphite, bronze, etc.) to meet specific mechanical or electrical requirements.
As a trusted factory direct supplier in China, Kaxite offers custom diameters and lengths, filled compounds, and competitive wholesale pricing. Request your price list and free sample →

Frequently Asked Questions – Molded PTFE Rods
What is the maximum temperature for PTFE rods?
PTFE rods can operate continuously up to 260°C (500°F), with short‑term peaks up to 300°C. At the low end, they remain flexible down to -200°C.
What are the advantages of filled PTFE rods over virgin PTFE?
Filled grades (glass, carbon, graphite, bronze) offer improved wear resistance, thermal conductivity, higher compressive strength, and lower creep compared to virgin PTFE, making them suitable for dynamic applications like bearings and seals.
Can you supply custom diameters and lengths?
Absolutely. We offer custom diameters from 5 mm to 400 mm and custom lengths up to 3000 mm. Please provide your specifications for a tailored quotation.
Are PTFE rods FDA‑compliant?
Yes, our virgin PTFE rods comply with FDA regulation 21 CFR 177.1550 and are suitable for food, beverage, and pharmaceutical contact applications.
What is the difference between molded and extruded PTFE rods?
Molded rods are compression‑molded in a press, allowing larger diameters and custom shapes. Extruded rods are produced by continuous extrusion, offering longer lengths and consistent quality for smaller diameters.
