Frequently Asked Questions
Q
What is the AS 9250 / AS 9275H adhesive primarily used for?
The AS 9250 / AS 9275H is specifically designed for soft-pack lithium battery film applications. It is used in the outer layer structure of lithium battery aluminum plastic film (NY/AL) with soft aluminum substrates, providing reliable bonding for aluminum‑plastic composite structures.
Q
What type of laminating equipment is compatible with AS 9250 / AS 9275H?
AS 9250 / AS 9275H is compatible with dry-type laminating equipment. It is not designed for use with flexo printing machines, solvent-free laminators, or coating machines, making it a specialized solution for dry lamination processes.
Q
What retort performance does AS 9250 / AS 9275H offer?
AS 9250 / AS 9275H delivers excellent retort performance at 135℃ for 40 minutes in aluminum‑plastic structures. This makes it highly suitable for demanding thermal environments encountered in lithium battery manufacturing and packaging.
Q
How does AS 9250 / AS 9275H perform against electrolytes and chemicals?
The adhesive offers excellent resistance to solvents, electrolytes, and various chemicals. This chemical resistance is critical for lithium battery applications where the laminate must maintain its integrity when exposed to aggressive electrolyte environments over long service periods.
Q
Is AS 9250 / AS 9275H suitable for multi-layer film structures?
Yes. AS 9250 / AS 9275H provides high initial tack and high peel strength, making it well-suited for bonding aluminum (AL) and other multi-layer composite structures. Its strong adhesion ensures structural reliability in complex laminate configurations used in battery packaging.
Q
What makes AS 9250 / AS 9275H suitable for deep drawing processes?
AS 9250 / AS 9275H is formulated as a high molecular weight polyester adhesive, which imparts excellent deep drawing resistance. This ensures the bonded film can withstand the mechanical deformation during the forming of battery pouch cells without delamination or failure.
