Everflon Fluoropolymer PTFE Fine Powder

Everflon® PTFE Fine Powder F500is a polytetrafluoroethylene fine powder resin used primarily for paste extrusion. Everflon® PTFE F500 offers the excellent combination of properties typical of Everflonfluoroplastic resins: 

• Non-aging characteristics 

• Chemical inertness tonearly 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,Everflon PTFE F500 is a premium resin that has increased thermal stability, superior flex life, superior stress crack resistance, low permeability, and high clarity. E

verflon PTFE F500 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. 

Everflon PTFE F500 meets the requirements of ASTM D4895

Main Application of Everflon Fluoropolymer PTFE F500

Everflon™ PTFE F500 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



Everflon™ PTFE F500 is extruded using a liquid processing aid, such as naphtha. In the paste extrusion process, the powder is mixed with a lubricant aid and then compressed into a cylindrical preform slug under light pressure (1.5–2.0 MPa [220–290 psi]).
The preform slug is placed in the cylinder of a paste extruder, where the composition is forced under high pressure through a finishing die to produce beading, tubing, or wire coatings. After extrusion, the product is a low-density, but coherent, fibrous structure.
Everflon™ PTFE F500 is usually processed further, with heat, into a solid resin product, such as tubing. Heat is applied in two steps, which may be taken in-line with extrusion or separately. The lubricant must be removed first, usually by heating within the range of 100–300 °C (212–572 °F). A sintering step follows to melt the resin above its melting point of approximately 342 °C (648 °F) and produce the void-free, solid PTFE resin.
