FAQ
Q: Can I visit your factory?
A: Sure! Welcome anytime.
Q: How about the payment items?
A: L/C, PAYPAL, T/T.
Q: Could you accept the inspection from a third party?
A: Yes. We have enough experience to cooperate with the inspection project.
Q: How long is the delivery time?
A: Usually, the shipment can be delivered within 10-15 days after the order is confirmed.
Q: Could COA and MSDS documents be provided for each batch?
A: For each batch, we can provide the complete set of COA and MSDS documents.
Q: Under the long-term immersion condition of the electrolyte, is the high-molecular-weight PVDF better at resisting swelling than the low-molecular-weight one?
A: Under the same conditions, the polymer with a higher molecular weight has better resistance to electrolyte swelling.
Q: Could the product be customized to adjust the viscosity index of the solution?
A: Sure. By adjusting the molecular weight of the polymer, the viscosity range of the solution can be customized. A corresponding minimum order quantity is required.
Q: After the PVDF powder gets damp during storage, can it regain its original properties after being dried?
A: Slight moisture absorption leads to drying and partial recovery; severe moisture absorption results in agglomeration and degradation, and the performance cannot be restored.
Q: When preparing lithium electrolyte paste, what requirements do the levels of solid content have for the selection of PVDF?
A: For high-solid-content slurries, PVDF with low viscosity is preferred as it is easier to mix and apply.
