New Advancement in the Polyvinylidene Fluoride (PVDF) Materials

Abstract: The continued growth of the Wire & Cable industry in renewables, electric mobility, data centers, fiber optics, and telecommunication is driving demand for higher-performing polymers in the wire and cable industry. Improved polymer durability in higher and lower temperature environments has become more critical as technology advances and infrastructure demands increase. To address such concerns, new PVDF polymers have been developed to keep up with changes in service conditions and corresponding demands. The following paper will present new developments in PVDF polymer technologies and standards related to performance cable applications. A new PVDF copolymer that can withstand a -60°C impact (35°C to 50°C improvement compared to typical PVDF copolymers) will be discussed to advance low-temperature properties. A new PVDF copolymer that can potentially achieve a temperature rating of 200°C after crosslinking will also be presented. Notably, the changes to UL1581 will be discussed, which now permits using these new flexible PVDF copolymers in communication cables. Finally, to help address the Oil and Gas industry needs, the new ASTM D 8436 entitled “Fluoropolymer based Materials for Use for Encapsulation of Downhole Cables” will be summarized, including performance data for PVDF polymers relevant to the new specification. About the Presenter: Azaz Vahora currently works as a Staff Engineer in the High Performance Polymers Division of Arkema Inc. He holds an M.Sc. (2021) in Material Engineering and B.Sc. (2012) in Chemical Engineering, both from Drexel University. Azaz has 11 years of experience with fluoropolymers, particularly with PVDF, for use in various fields, including the chemical processing industry, wire and cables, water filtration, 3D printing, energy storage and fuel cell. He is based at Arkema Inc.’s North American Headquarters in King of Prussia, PA. This technical paper was originally presented at last year's IWCS Forum. Plan to attend the 2024 IWCS Cable & Connectivity Industry Forum October 14–16 in Providence, Rhode Island, USA. Visit https://iwcs.org for details.
