Polyvinylidene Fluoride(PVDF)-5130

Name: Solvay Solef 5130 PVDF Binder for Lithium-Ion Batteries

Manufacturer: Solvay (Belgium)

Model: Solef 5130

Product Code: XN-BD-PVDF5130

Description:

Solvay Solef 5130 is a polyvinylidene fluoride (PVDF) homopolymer manufactured by Solvay (Belgium) via suspension polymerization. The product is supplied as a fine white powder for use in lithium-ion battery binder applications. Solef 5130 is supplied with the following specifications: density 1.75–1.78 g/cm³, water absorption < 0.20%, melting point 316–331 °F (158–166 °C), thermodynamic stability > 707 °F (> 375 °C), intrinsic viscosity 0.27–0.31 L/g. Available in 1 kg packaging.

Application:

Solvay Solef 5130 is used in lithium-ion battery binder applications where PVDF is the binder system. PVDF is dissolved in NMP (N-methyl-2-pyrrolidone) for use in standard wet-process electrode coating workflows.

NMP-soluble

Solef 5130 dissolves in N-methyl-2-pyrrolidone (NMP), the standard solvent for wet-process PVDF cathode slurry preparation.

Solvay manufacturer

Solvay (Belgium) is a global supplier of fluoropolymer chemistries.

Recommended Use Procedure:

1. Pre-dissolve Solef 5130 in NMP (N-methyl-2-pyrrolidone) before adding to slurry. Add PVDF powder slowly to vigorously stirred NMP at moderate temperature; avoid forming clumps that resist dissolution. 2. Continue stirring until the PVDF is fully dissolved as a clear viscous solution. 3. Use the dissolved PVDF solution as the binder in standard NMP-based cathode slurry formulations. 4. Filter the final slurry through a fine-mesh filter to remove any aggregates. 5. Coat onto current collector foil using standard coating equipment. 6. Dry the coated electrode at recommended temperatures to remove NMP solvent. 7. Reseal the PVDF container tightly between uses to minimize moisture absorption.

Packaging & Storage:

Solvay Solef 5130 is supplied in 1 kg packaging, sealed for shipment and storage. Store at room temperature in a dry and sealed environment. PVDF powder is hygroscopic — moisture absorption from humid air will alter the moisture content and may affect dissolution behavior, slurry rheology, and final electrode quality. After opening, reseal the container tightly between uses.

Safety:

For research and industrial laboratory use only. Always wear appropriate PPE (safety glasses, chemical-resistant gloves, lab coat) when handling PVDF binder, NMP solvent, or coated electrodes. NMP is a regulated chemical in many jurisdictions (REACH, OSHA) — handle in a fume hood and follow local regulations on solvent use. Avoid prolonged inhalation of PVDF powder dust during weighing and slurry mixing operations. Do not store near oxidizers, strong acids, or strong bases. Refer to the Solvay Material Safety Data Sheet (MSDS) for complete safety and handling information.

Note: Specifications listed above are typical values provided by Solvay and are for reference only. Actual performance depends on the specific cathode active material, slurry formulation, NMP quality, coating process parameters, and downstream cell manufacturing conditions — consult published literature and Solvay technical bulletins for guidance on optimal PVDF binder formulation protocols.
