Product Description
Everflon Fluoropolymer PTFE Fine Powder
Everflon® PTFE Fine Powder F100 is a polytetrafluoroethylene fine powder resin used primarily for paste extrusion. Everflon® PTFE F100 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. Everflon PTFE F100is designed for processing at low to medium reduction ratios of 10:1 to 300:1. It is designed to facilitate the production of high-quality, low-density tape and beading. Everflon PTFE F100 meets the requirements of ASTM D4895, Main Porperties Everflon Fluoropolymer PTFE Fine Powder F100
Main Application of Everflon Fluoropolymer PTFE F100
Everflon™ PTFE F100 is widely used for conformable, high performance sealing materials and as tape for wire and cable insulation.
Processing
Everflon™ PTFE F100 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. After removal of the lubricant by heating within the range of 100–300 °C (212–572 °F), the extrudate can be either
sintered above its melting point of around 345 °C (653 °F) to produce a void-free PTFE article or calendered and stretched to produce unsintered or semisintered articles.
