Teflon® PTFE 62N X | |||
Polytetrafluoroethylene | |||
Product Description: | |||
DuPont ™ Teflon ® PTFE 62N X is a polytetrafluoroethylene fine powder resin used primarily for paste extrusion. Teflon ® PTFE 62N 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 62N X is a premium resin that has increased thermal stability, superior flex life, superior stress crack resistance, low permeability and high clarity. | |||
Teflon ® PTFE 62N X is designed for processing at low to medium reduction ratios of 100:1 to 600:1. It is in particular suitable for production of high quality tubing, spaghetti tubing ,wire coating and extruded shapes. This grade is also highly suitable for after processing technologies such as flanging, welding, blow moulding, convoluting. | |||
Teflon ® PTFE 62N X meets the requirements of ASTM D4895-10, Type I, Grade 4, Class B. | |||
Typical Applications | |||
Teflon ® PTFE 62N 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. | |||
