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.
