FEP, or fluorinated ethylene propylene, is a melt-processable fluoropolymer known for excellent chemical resistance, high temperature tolerance, low friction, and electrical insulation. It is commonly used in wire and cable insulation, tubing, linings for pipes and tanks, medical device components, and other applications requiring durable, non-stick, and chemically inert materials.

PTFE gaskets exhibit exceptional chemical resistance, compatible with nearly all acids, bases, solvents, and industrial chemicals, excluding only molten alkali metals and certain fluorinating agents under extreme conditions.

PTFE Teflon film typically has an indefinite shelf life when kept in a cool, dry environment away from direct sunlight and contaminants. Its inherent chemical stability prevents degradation over time, though physical damage from improper handling or storage can affect performance.

Different fillers can significantly affect the chemical resistance of PTFE compounds. This article explores how various filler materials perform in aggressive chemical environments, helping you choose the best option for your application.

Discover the recommended cutting speeds and feed rates for machining PTFE, helping you achieve clean, accurate parts without melting or deforming the material.

PTFE packing is widely used in valves, pumps, and other rotary or reciprocating equipment to provide a durable, leak-proof seal that resists aggressive chemicals, high temperatures, and friction.

PTFE O-rings are manufactured in an extensive variety of sizes, encompassing standard AS568 inch-series dash numbers, widely used metric dimensions, and fully custom configurations to meet specific sealing requirements, with common cross-sections ranging from approximately 1 mm to over 10 mm and inner diameters available from a few millimeters up to several hundred millimeters.

A PTFE ball typically has a density around 2.2 g/cm³, though the exact value can vary slightly based on the specific grade and manufacturing process of the polytetrafluoroethylene.

PTFE tape may leak if applied incorrectly, such as wrapping against the thread direction, using too little or too much tape, or failing to cover all the threads properly. Other causes include using the wrong tape grade for the pipe material or fluid type, and damaged or deteriorated tape.
