HONG YE SILICONE Liquid Silicone Foam Delivers All-Day Comfor

Footwear comfort depends on what happens between the foot and the sole — yet conventional insole foams flatten permanently, absorb sweat and odor, and lose their support within months of daily wear. HONG YE SILICONE's liquid silicone foam, a platinum-cured two-component addition curing silicone rubber, is now upgrading insoles and foot pads with a material that keeps its cushioning and support for the life of the shoe.

The excellent rebound resilience of the foam provides consistent cushioning and pressure distribution that recovers after every step, maintaining all-day comfort and support for demanding users — from workers on their feet to runners on the road. Its uniform cell structure distributes body pressure evenly, reducing foot fatigue and improving comfort in long-wear applications.

The closed-cell structure resists sweat and moisture, keeping insoles dry, odor-free, and hygienic during prolonged use — a critical advantage in footwear. Non-toxic and skin-friendly, the material is safe for direct foot contact, while the wide service temperature range of -65°C to 200°C maintains performance from winter boots to summer sandals.

The 2× to 7× expansion ratio reduces material consumption and product cost, and the simple 1:1 mixing ratio supports efficient production. Produced under ISO9001-certified quality control, certified to UL and CE standards, and exported to buyers in more than 138 countries, HONG YE SILICONE helps footwear manufacturers build shoes and insoles that deliver comfort — step after step, day after day.
