High-Expansion Liquid Silicone Foam

Against the background of increasingly stringent sealing standards worldwide, high expansion and stable rebound have become key assessment indicators for gasket and sealing-strip materials. Many overseas end-users hope to reduce material consumption while maintaining reliable sealing performance under long-term compression.

The upgraded Liquid Silicone Foam adopts an optimized Addition Curing Silicone base material; it can achieve a uniform closed-cell structure after mixing and foaming, with foaming ratios from 2 times up to 7 times, low shrinkage rate, good resilience and excellent compression recovery. Compared with conventional Foam Silicone, the new grade effectively cuts down material weight and keeps stable sealing performance over a wide working temperature range from -65°C to 200°C.

At present, sample requests from Europe, Southeast Asia and the Middle East are increasing. Technical teams are providing customized density, hardness and foaming-ratio adjustment services according to actual working conditions of sealing strips, gaskets and foam boards. Market insiders mentioned that high-expansion liquid silicone foam will occupy a larger market share in sealing, cushioning and thermal insulation fields in the next few quarters.
