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  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 

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 requirements of ASTM D4895,  Type 1, 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.
