Teflon® PTFE 605XT X

DuPont ™ Teflon ® PTFE 605XT X is a polytetrafluoroethylene fine powder resin used primarily for paste extrusion. Teflon ® PTFE 605XT 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 605XT X is designed for processing at low to medium reduction ratios of 10:1 to 300:1. It is particularly suitable for unsintered stretched products and for sintered products with high mechanical properties.

Teflon ® PTFE 605XT X meets the requirements of ASTM D 4895-91a, Type I, Grade 4, Class A.

Typical Applications
Teflon ® PTFE 605XT X is mainly used for unsintered articles including filter membranes and gaskets. It is also used for making sintered products such pipe liners and tubes.
