PTFE (TEFLON) RODS
PTFE (Polytetrafluoroethylene) rods, commonly known by the trademark Teflon® rods, are solid cylindrical bars made from a high-performance fluoropolymer. PTFE is renowned for its exceptional chemical inertness, non-stick properties, and ability to operate in extreme temperatures. These rods are manufactured through compression molding or extrusion processes and are widely used in industries requiring durability, low friction, and resistance to harsh environments. PTFE rods come in various diameters and lengths and are often machined into custom components or used as finished parts in sealing, insulation, and sliding applications.
Key Features:
-Exceptional Chemical Resistance:
PTFE is virtually immune to acids, bases, solvents, and many corrosive chemicals, making it ideal for chemical processing and handling aggressive media.
-Ultra-Low Friction Coefficient:
Its non-stick surface minimizes friction, ensuring smooth operation in moving parts and reducing wear.
-Wide Temperature Range:
PTFE rods can perform in environments from cryogenic temperatures up to around 260°C, ensuring durability in both extreme cold and high-heat conditions.
-Electrical Insulation:
With excellent dielectric properties, PTFE rods are often used in electrical applications requiring high voltage resistance.
-Non-Adhesive Surface:
The low surface energy of PTFE prevents the buildup of materials, facilitating easy cleaning and reducing contamination risks.
-Self-Lubricating:
Due to their inherent low friction, PTFE rods often require no additional lubrication, which simplifies maintenance in dynamic systems.
-Biocompatibility:
They are suitable for medical and food processing applications when manufactured under stringent quality standards.
