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.
