Teflon® PTFE 62 X

DuPont ™ Teflon ® PTFE 62 X is a polytetrafluoroethylene fine powder resin used primarily for paste extrusion. Teflon ® PTFE 62 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.

Compared with other grades of PTFE fine powder, Teflon® PTFE 62 X is a premium resin that has increased thermal stability, superior flex life, superior stress crack resistance, low permeability and high clarity.

Teflon® PTFE 62 X is designed for processing at medium to high reduction ratios of 100:1 to 600:1. It is particularly suitable for production of high quality tubing, spaghetti tubing and wire coating. This grade is also highly suitable for after-processing technologies such as flanging, welding, blow molding and convoluting.

Teflon® PTFE 62 X meets the following requirements:

• ASTM D4895-10, Type I, Grade 4, Class B

Typical Applications
Teflon® PTFE 62 X is mainly used for tubing installed in demanding applications. It includes high performance articles such as reinforced hose requiring the ultimate in reliability and performance in chemical, pharmaceutical and automotive industry in use with hydraulic fluid, hydrocarbon fuel or reactive gas. Such applications are for example overbraided hoses for fuel assemblies and brake systems.
