Development background of Youxingshark SY-2474

　　One of the core competitive points of new energy vehicles is cruising range. The vehicle weight, battery pack weight and battery pack capacity are the three core key indicators that affect the cruising range of new energy vehicles. In the context of the current adoption of CTP battery pack technology, Youxingshark's low-density structural adhesive SY-2474 exhibits mechanical properties comparable to traditional power battery structural adhesives. At the same time, its density is as low as 0.78g/cm³, which significantly reduces the weight of the battery pack. weight, making an important contribution to improving the endurance of new energy vehicles.

　　SY-2474 Product Description

　　Youxingsha SY-2474 is a two-component polyurethane structural adhesive that cures at room temperature and is suitable for automated production. This product has good mechanical properties and reliable bonding; very low density; good vibration and impact resistance; excellent high and low temperature resistance and aging resistance; solvent-free and friendly to the human body and the environment. It is suitable for a wide range of bonding and has no corrosion to the base material.

　　SY-2474 main application areas

　　It is used for structural bonding of new energy power batteries and plays a role in reliable connection and fixation.

　　SY-2474 Cured Characteristics

　　SY-2474  focuses on performance

　　Density and bonding strength:

　　Different from traditional fuel vehicles, the driving core of new energy vehicles is the three-electric system (battery, motor, and electronic control). Compared with fuel vehicles, its weight increases by 10 to 30%. In particular, the power battery pack accounts for a large portion of the entire vehicle. 18~30% of the quality. Making the power battery pack "downslim" and improving the vehicle's cruising range has always been an important issue in the development of new energy vehicle technology. The density of Youxingsha SY-2474 is as low as 0.78g/cm³. Compared with the existing mainstream structural adhesives, the weight of the colloid is reduced by 40 to 50% under the premise of the same volume of glue. At the same time, as a structural bonding material between battery cells, it has high strength and can withstand large loads. And it has the characteristics of aging resistance, fatigue resistance, corrosion resistance, impact resistance, simple construction, and stable performance within the expected life.

　　In the future, the energy density and space utilization of new energy power battery packs will become increasingly higher. Choosing the right structural adhesive can improve your car's performance. Youxingsha has accumulated certain technical strength and applications in the diverse scenarios such as thermal management and lightweighting of new energy power batteries, helping customers cope with more complex new energy battery usage environments, high performance and reliability requirements.
