Low-Density Liquid Silicone Foam Gains Traction in EV Battery

With the rapid growth of the electric vehicle and consumer electronics markets, customers are putting forward higher requirements for lightweight, shock-absorbing and flame-retardant materials. A domestic silicone material manufacturer has adjusted its formula for Liquid Silicone Foam, successfully launching low-density addition curing foam products, which have drawn steady inquiries from overseas buyers.

Against the background of global EV expansion and smart device development, lightweight protection has become one of the key assessment indicators for accessory materials. Many overseas end-users hope to reduce the overall weight of equipment while maintaining reliable cushioning, sealing and flame-retardant performance.

The upgraded Liquid Silicone Foam adopts an optimized addition curing silicone base material; it can realize a uniform closed-cell structure after mixing and foaming, with low shrinkage rate, good resilience and stable cushioning performance. Compared with conventional foam silicone, the new grade effectively cuts down material weight, and keeps stable performance over a wide working temperature range from -65°C to 200°C.

At present, sample requests from Europe, North America and Southeast Asia are increasing. Technical teams are providing customized density, hardness and color adjustment services according to actual working conditions of battery modules, seal strips and electronic cushioning components. Market insiders mentioned that low-density liquid silicone foam will occupy a larger market share in cushioning, sealing and thermal insulation fields in the next few quarters.
