Description
Polytetrafluoroethylene (PTFE) Binder – 60% Solid Content Emulsion for Battery Electrodes
Polytetrafluoroethylene (PTFE) binder is a fine dispersion liquid specifically formulated for battery electrode preparation. Stabilized with non-ionic surfactants, this PTFE emulsion offers a condensed solid content of up to 60%, making it highly effective as a binding agent in electrode paste formulations.
Key Characteristics:
- High Solid Content: 60% ± 2% PTFE solids for efficient binding with minimal diluent.
- Fine Particle Size: Grain size of 0.05μm (D0.2) ensures uniform dispersion in electrode slurries.
- Excellent Thermal Resistance: PTFE’s inherent high temperature stability contributes to electrode performance.
- Superior Electric Insulation: Ideal for applications requiring electrical isolation between components.
- Stable Emulsion: Non-ionic surfactant stabilization prevents coagulation and ensures consistent quality.
- Controlled Viscosity: Kinematic viscosity of 6 mm²/s (25°C) for good processability.
- Neutral pH: pH 7 compatible with various electrode formulations.
Applications:
- Lithium-ion battery electrode paste preparation
- Cathode and anode binder systems
- High-temperature electrode applications
- Research and development of advanced battery materials
- Laboratory-scale electrode formulation
