Typical Applications


Everflon™ ETFE 4003 is ideal for many end products, including chemical service items, such as lined valves and fittings, pump housings and impellers, column packings, and other abrasionresistant linings; high temperature electrical components and insulation; fasteners, corrugated tubing, and duct work and film.

Processing Guide

Everflon™ ETFE 4003 can be processed by conventional, melt-extrusion techniques and injection, compression, transfer, and blow molding processes. Compared with other grades of Everflon™ ETFE, it can be processed with greater ease and speed because of its high flow rate. Also, the melt viscosity of Everflon™ ETFE is reduced with increasing shear rate; thus, permitting the use of pressure extrusions through narrow dies without requiring appreciable drawdown. Reciprocating screw injection molding machines are preferred. Corrosion-resistant metals are recommended for contact with molten resin. Extruder barrels should be long, relative to diameter, to provide residence time for heating the resin to approximately 340 °C (640 °F).
 
Precaution

Equipment used to process at melt temperatures should be provided with local exhaust ventilation (LEV) to completely remove all fumes and vapors from the processing area. In addition, care should be exercised to avoid the contamination of cigarettes and other forms of smoking tobacco when using fluoroplastic resins. Before processing any fluoroplastics, read the Material Safety Data Sheet.
