Product Overview
Yinlin Ultrathin-VIP is a vacuum insulation panel (VIP) engineered to provide high thermal resistance within minimal thickness for thermal management of new energy lithium battery packs. Compared with conventional insulation materials, it delivers multiple times the thermal resistance while occupying very little space, helping to improve battery power retention at low temperatures.

Advantages

• Improves low-temperature performance of power batteries by reducing heat loss
• Very thin construction with small volume and low weight
• Thermal resistance approximately 8–10 times that of traditional materials
• Porous core reduces solid conduction
• High vacuum inside the panel minimizes convective heat transfer
• Composite reflective films reduce radiative heat transfer
