Low-Density Liquid Silicone Foam

Against the background of growing pharmaceutical, biological and fresh-food cold chain demand, lightweight thermal insulation has become one of the key assessment indicators for packaging accessory materials. Many overseas end-users hope to reduce the overall weight of shipping containers while maintaining reliable temperature-holding performance during long-distance transport.

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 excellent thermal insulation effect. Compared with conventional foam insulation, the new grade effectively cuts down material weight, repels moisture, and keeps stable performance under long-term alternating hot and cold working conditions.

At present, sample requests from Europe, Southeast Asia and the Middle East are increasing. Technical teams are providing customized density, hardness and thickness adjustment services according to actual working conditions of insulated shipping boxes, cold-chain liners and temperature-controlled cabinet sealing. Market insiders mentioned that low-density liquid silicone foam will occupy a larger market share in cold chain insulation, cushioning and sealing fields in the next few quarters.
