PUR 1610 Cell Structural Adhesive: Low-Stress, High-Reliability Bonding Solution for New Energy Batteries
During the assembly of power batteries for new energy vehicles, energy storage battery modules, lithium battery PACKs and battery cells, stable and reliable structural adhesives are required for bonding cell-to-cell, cell-to-aluminum shell, and cell-to-bracket joints. Cell structural adhesives serve far more than merely fixing cells in place. They directly determine the vibration resistance, structural stability, stress buffering performance and long-term operational reliability of battery modules. For battery manufacturers, ideal lithium battery structural adhesives must strike a balanced performance across bonding strength, flexibility, aging resistance, process compatibility and environmental compliance. ELAPLUS (Elaplus Functional Materials (Shanghai) Co., Ltd.) has developed PUR 1610 A/B two-component polyurethane adhesive, a dependable material tailored for cell structural bonding, aluminum battery shell bonding and multi-substrate structural fixation in new energy batteries. 1. Why Bonding Strength Alone Cannot Define Cell Structural Adhesive Performance Power and energy storage batteries operate continuously under harsh service conditions: persistent vibration, mechanical impact, thermal cycling, high-temperature humid environments, and thermal expansion mismatches between dissimilar materials. Overly rigid structural adhesives trigger severe stress concentration, while insufficient bonding strength may lead to cell loosening, structural cracking or interface failure. Therefore, cell structural adhesives must deliver a full set of capabilities: ■ Stable structural fixation capacity ■ Optimized flexibility matching battery structures ■ Excellent shock absorption and vibration resistance ■ Strong adhesion compatibility with aluminum, plastics, rubber, polyester and other substrates ■ Long-term resistance to aging and chemical corrosion ■ Compatibility with automated dispensing and mass production workflows The core value of PUR 1610 lies in its well-tuned balance between robust adhesion and low stress, perfectly adapted to new energy battery structural requirements. 2. Product Introduction: What Is PUR 1610? PUR 1610 A/B is a 1:1 two-component solvent-free room-temperature curing polyurethane structural adhesive developed by ELAPLUS, designed for structural bonding and sealing across various substrates. It excels at aluminum-to-aluminum bonding for new energy…
