Description
Teflon ™ PTFE 650XT X is a polytetrafluoroethylene fine powder resin used primarily for paste extrusion. Teflon ™ PTFE 650XT 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 650XT X is designed for processing at low to medium reduction ratios of 10:1 to 400:1. It is particularly suitable for unsintered mono-axial and multidirectional stretched products and sintered products with high mechanical properties.

Teflon ™ PTFE 650XT X meets the requirements of ASTM D4895-15, Type I, Grade 1, Class A.

Typical Applications
Teflon ™ PTFE 650XT X is mainly used for unsintered high demanding articles, such as filter membranes with uniform porosity and gaskets with excellent mechanical properties. It is also used for making sintered products.
