Description
Teflon ™ PTFE 7C X is a white powder with a small particle size. The small particle size of Teflon ™ PTFE 7C X helps to minimize voids, even at relatively low molding pressures. Its most unique feature is the irregular, fibrous character of the particles. The fibrous particles promote good capture and uniform distribution of inorganic fillers when they are added to modify the mechanical properties of moldings. It offers an excellent combination of properties that are characteristic of Teflon ™ fluoroplastic resins:

• Chemical inertness

• Exceptional dielectric properties

• Heat resistance

• Toughness and flexibility

• Low coefficient of friction

• Non-stick characteristics

• Negligible water absorption

• Excellent weather resistance

Teflon ™ PTFE 7C X is preferred for moldings requiring optimum mechanical and electrical properties. Its low bulk density limits the size of moldings from a given mold or press opening. It is often preferred for making filled compounds, especially with metal powders that are difficult to mix because of density differences.

Typical Applications
Many end products are fabricated, which include skived film and sheet. It can be used for applications, such as:

• Gasket

• Bridge or pipeline bearing pads

• Piston rings

• Diaphragms

Many end products are made with filled compounds based on Teflon ™ PTFE 7C X. The filled compounds provide a wide choice of modified mechanical properties.
