What is the maximum operating temperature for this glass fiber separator?
The product description states the material is thermally stable but does not specify a maximum operating temperature. For precise thermal limits, please contact our engineering team for technical support.
This 290 μm glass fiber separator, supplied as a 120 mm x 100 m roll, offers a high-porosity (>90%), hydrophilic, and binder-free structure with a uniform pore size of 1.63 μm, making it suitable for battery separator and filtration applications requiring thermal stability and consistent performance.
Positive
- High porosity and hydrophilicity: With porosity exceeding 90% and a hydrophilic, binder-free nature, this separator promotes rapid electrolyte wetting and ionic transport, which is critical for battery performance and filtration efficiency.
- Thermal and mechanical robustness: The material exhibits high puncture and tensile strength along with excellent thermal stability, ensuring dimensional integrity and resistance to mechanical stress during cell assembly and operation.
Trade-offs
- Lot-to-lot variability: Slight variations may occur between production lots, which could affect consistency in pore size or thickness, requiring verification against specifications for critical applications.
- Handling sensitivity of thin film: At 290 μm thickness, the material may be prone to creasing or tearing during manual handling, necessitating careful processing and storage to maintain structural integrity.
