DuPont Chemicals & Fluoroproducts Introduces Melt-Processible Fluoroplastic Resin Offering for the Cabling Industry

Wilmington, DE, December 2, 2013

Teflon™ FEP 9835 has Lower Melt Flow Rate, Offers Better Stress Crack Resistance and Better Burn Performance While Maintaining Exceptional Electrical Performance

DuPont Chemicals & Fluoroproducts has developed a new fluorinated ethylene propylene (FEP) resin, Teflon™ FEP 9835, a melt-processible fluoroplastic resin primarily for use in cabling. With a relatively high melt flow rate and excellent electrical properties, Teflon™ FEP 9835 has been specifically designed for high-speed extrusion of thin coatings on small-gauge wires for twisted-pair constructions. Compared to Teflon™ FEP 9494, Teflon™ FEP 9835 has the same outstanding electrical performance with better stress crack resistance and excellent burn performance in the Steiner tunnel test.

 

Teflon™ FEP 9835 provides electrical and mechanical properties for low voltage applications, including small diameter, thin-wall wire and cable insulation; industrial film; and intricate or thin wall parts – such as connectors – made by injection molding. In addition, Teflon™ FEP 9835 has a higher melt flow rate than most other fluoroplastic resins, permitting higher extrusion speeds and easy processing – making it a cost-effective resin for producing thin-wall extrusions. Teflon™ FEP 9835 offers excellent adhesion to copper wire under specific wireline process conditions, low dissipation factor at high frequencies and significant plate-out resistance in melt extrusion. It is suitable as a solid insulator and can be foamed when used with an appropriate nucleant.

 

“Teflon™ FEP 9835 is the latest in a series of recent new product launches from DuPont to support our customers in the wire and cable industry,” said Frenk Hulsebosch, global business manager, DuPont Fluoropolymer Solutions. “Teflon™ FEP 9494 is well-known in the industry and we’re pleased to offer Teflon™ FEP 9835 for those looking for a material with a lower melt flow rate. We continue to push the envelope in developing new technologies and we look forward to introducing future innovations.”

 

Compared to other thermoplastics, the high melt strength and thermal stability of Teflon™ FEP 9835 can be used to improve processing rates. Compared with other fluoroplastics, creep resistance at high service temperatures provides a superior balance and level of end-use properties. Teflon™ FEP 9835 combines the processing ease of conventional thermoplastics with many properties similar to those of polytetrafluoroethylene. Properly processed products made from neat Teflon™ FEP 9835 resin provide the superior properties characteristic of fluoroplastic resins, such as chemical inertness, exceptional dielectric properties, heat resistance, toughness and flexibility, low coefficient of friction, nonstick characteristics, negligible moisture absorption, low flammability, performance at temperature extremes and excellent weather resistance. In a flame situation, products of Teflon™ FEP 9835 resist ignition and do not promote flame spread.

 

Teflon™ FEP 9835 is a copolymer of tetrafluoroethylene and hexafluoropropylene, without additives, that meets the requirements of ASTM D 2116 type II. It is supplied as pellets and is available in 25-kg. single layer plastic bags and in 1000 kg. bulk containers. For more information, please visit http://pages.chemours.com/Teflon_FEP_9835.html.
