Get to know Everflon™ FEP 4610X.

Everflo^nultra™ FEP 4610X is a modified melt-processible copolymer of TFE,HFP and PPVE, without additives.

It offers the excellent combination of prop-erties characteristic of Everflon™ fluoroplastic resins: non-aging characteristics, chemical inertness, exceptional dielectric properties, low flammability, heat resis-tance, toughness and flexibility, low coeffi-cient of friction, non-stick characteristics, negligible moisture absorption, and excel-lent weather resistance. As an intermediate molecular weight resin, Everflo^nultra™ FEP 4610X offers higher processing speeds than many FEP grades with similar high level of stress crack resistance.

Stress crack resistance is an important element in establishing end-use performance. Extensive testing of wire and cable constructions is required for definitive performance evalua-tion.

Experience shows that the MIT folding endurance or flex life test, performed on a thin film of resin, has established a good correlation with extensive cable testing. The higher the MIT flex life, the higher the stress-crack resistance of the resin.

MIT test results should be viewed as a guide to comparative performance of the various grades of resin. We recommend that for applications involving repeated thermal and flex cycling, spe-cific tests on the final cable always should be undertaken.

Processing Guide

Everflon^ultra™ FEP fluoroplastic resin can be processed by conventional melt extrusion, and by injection, com-pression, and blow molding processes. For smooth feeding to extrusion equipment, it is supplied in 3 mm (0.12 in) pellets. The extruders and molding machines used for Everflon™ FEP should be constructed of high nickel alloy corro-sion-resistant materials and be capable of operating at temperatures up to 400 °C (750 °F).

Precaution

Industrial experience has proven that adequate ventilation, in properly maintained processing and handling areas, will eliminate known hazards to personnel. Resin containers should be opened and used in well-ventilated areas. Equipment used to process at melt temperatures should be provided with local exhaust ventilation (LEV) to com-pletely 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, available upon request from our Customer Service Group. Also read the detailed information in the latest edition of the “Guide to the Safe Handling of Fluoropolymer Resins”.
