Low-Density Liquid Silicone Foam Gains Traction

Against the background of growing demand for professional running shoes, work footwear and orthopedic insoles, lightweight cushioning has become one of the key assessment indicators for footwear accessory materials. Many overseas end-users hope to reduce the overall weight of shoes while maintaining reliable support and pressure distribution performance during long-term wear.

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 insole foams, the new grade effectively cuts down material weight, resists sweat and moisture, and keeps stable resilience under long-term repeated compression and alternating hot and cold working conditions.

At present, sample requests from Europe, Southeast Asia and North America are increasing. Technical teams are providing customized density, hardness and thickness adjustment services according to actual working conditions of running insoles, work boots and orthopedic foot pads. Market insiders mentioned that low-density liquid silicone foam will occupy a larger market share in footwear cushioning, insoles and comfort products fields in the next few quarters.
