Description
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
