Solef® and Hylar® PVDF are semi-crystalline fluoropolymers widely known for their excellent performance in a very broad range of applications.
Solvay Solexis' PVDF product family offers a wide choice of grades, ranging from highly crystalline PVDF homopolymers to extremely flexible VDF-HFP and VDF-CTFE copolymers.
Hylar® is an ASTM D-3222 Type I resin while Solef® is an ASTM D-3222 Type II resin.
Markets and Applications
Piping systems: Solef® and Hylar® are widely used in piping systems for ultrapure water, hot, concentrated acids; pharmaceutical grade chemicals; chrome plating chemicals and more. They are also materials of choice for the construction of flexible risers for off-shore oil & gas extraction as well as for off- and on-shore distribution.
Pumps, vessels, etc.: Solef® and Hylar® are found also in other fluid handling components such as pumps, vessels, meters, valves, tubing, quick disconnect couplings, sinks, filter housings, and flow meters.
Mono- and multi-filament: Solef® and Hylar® are also used to manufacture mono- and multi-filaments.
Plumbing applications: Solef® has been also used for over 20 years in plumbing applications, including domestic water supply and heating systems thanks to its mechanical properties and ageing resistance.
Wire & cable: Solef® VDF-HFP copolymers are widely used for jacketing copper plenum cables and for plenum rated optical fiber raceways thanks to their outstanding fire resistance. Solef® VDF-CTFE copolymers combine improved flexibility, low shrinkage, and an expanded range of service temperatures.
Membranes & lithium-ion batteries: Solef® and Hylar® are also utilized in the fabrication of lithium-ion batteries and of special water filtration membranes.
Films: Solef® PVDF films are ideally suited as a component in back sheet laminates used in photovoltaic modules. PVDF offers an excellent combination of properties from UV stability to water vapor permeation resistance making it an excellent choice. Solef® can be laminated to PET to provide the traditional fluoropolymer-PET-fluoropolymer or fluoropolymer-PET structure currently available in the marketplace.
Moreover, Solef® and Hylar® offer novel solutions for several new challenging applications. Their characteristics - high purity, resistance to solvents and acids, excellent dimensional stability, mechanical strength, high dielectric and piezoelectric properties, UV stability, and ease of processing - make them suitable for cutting edge uses in aerospace, fuel cells, microelectronics, sensors, biotechnology, and robotics.
