Teflon™  PTFE 7A X is a white powder with a small particle  size. Its small particle size helps to minimize voids, even at  relatively low molding pressures. High bulk density increases  the size of moldings possible from a given mold or press  opening. Teflon™  PTFE 7A X is preferred for large moldings  requiring optimum mechanical and electrical properties.  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 

Properly processed products made from neat Teflon™  PTFE  7A X provide the superior properties typical of fluoroplastic  resins. It’s easy to process, handle, and machine.  

Typical Applications  

Many end products are fabricated from billets, which include  skived film and sheet. It can be used for applications, such as: • Gaskets • Packings • Mechanical seals • Bridge or pipeline bearing pads • Shaft bearings • Electrical insulators • Piston rings • Expansion bellows • Diaphragms • Chemical linings 

The use of fillers provides a wide choice of modified  mechanical properties.
