Adhesive for Soft-pack Lithium Battery Films

AS 9250/AS 9275H adhesive for soft-pack lithium battery films is a high-performance special bonding solution specially developed for the lamination scenario of soft-pack lithium battery aluminum plastic films. It focuses on the core needs of long-term stable operation of soft-pack lithium batteries, accurately adapts to the outer layer structure of lithium battery aluminum plastic film (NY/AL) for soft-pack batteries, optimizes the formula according to the characteristics of soft aluminum substrates, adopts the dry lamination process, can quickly adapt to the soft-pack lithium battery film production line, and provides firm, stable and long-term bonding guarantee for the lamination of various layers of soft-pack lithium battery aluminum plastic films. As a high molecular weight polyester product, the formula is professionally optimized, strictly complying with the strict standards of the soft-pack lithium battery industry, with excellent high temperature resistance, electrolyte resistance, solvent resistance and chemical resistance. The colloid is flexible and has outstanding deep drawing resistance, which can easily adapt to complex processing procedures such as deep drawing and forming in the production of soft-pack lithium battery aluminum plastic films, effectively avoiding problems such as adhesive layer breakage and degumming during processing. At the same time, the product has high initial tack and high peel strength, fast bonding forming speed, which can effectively improve the production efficiency and product qualification rate of soft-pack lithium battery films, ensure the sealing and barrier properties, structural stability and electrolyte erosion resistance of aluminum plastic films, prevent electrolyte leakage, adapt to the packaging needs of various soft-pack lithium battery aluminum plastic films, help soft-pack lithium batteries achieve safe, long-term and stable operation, and provide reliable bonding support for the new energy lithium battery industry.
