DuPont ™ Teflon ® PTFE 669 X is a polytetrafluoroethylene fine powder resin used primarily for paste extrusion. Teflon ® PTFE 669 X offers the excellent combination of properties typical of the Teflon ® fluoropolymer resins:

• non-aging characteristics;

• chemical inertness to nearly all industrial chemicals and solvents;

• exceptional dielectric properties, stable with frequency and temperature;

• toughness and flexibility;

• low coefficient of friction;

• non-stick characteristics;

• negligible moisture absorption;

• excellent weather resistance;

• service temperature up to 260°C (500°F);

• useful properties at -240 °C (-400 °F);

• moderate stiffness and high ultimate elongation.

Teflon ® PTFE 669 X is designed for processing at very low to medium reduction ratios (10:1 to 500:1). It is particularly suitable for production of pipe liners and general tubing.

Teflon ® PTFE 669 X meets the requirements of ASTM D4895-91a, Type I, Grade 2, Class A.

Typical Applications
Teflon ® PTFE 669 X is mainly used for the production of pipe liners used in the chemical industry. It is also used for making tubing and unsintered tape for mechanical, chemical and electrical applications.
