Teflon® PTFE 669N X PTFE绝缘材料

Description
Teflon ™ PTFE 669N X is a polytetrafluoroethylene fine powder resin used primarily for paste extrusion. Teflon ™ PTFE 669N X offers the excellent combination of properties typical of Teflon ™ fluoroplastic 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 669N 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 669N X meets the requirements of ASTM D4895-91a, Type I, Grade 2, Class A.

Typical Applications
Teflon ® PTFE 669N 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.
