HONG YE SILICONE Liquid Silicone Foam Expands

2026,10,22

As the electric vehicle industry accelerates, battery safety and reliability have become the industry's top priorities. In battery packs, every component must withstand vibration, thermal expansion, and extreme temperature changes over years of service. HONG YE SILICONE's liquid silicone foam, a platinum-cured two-component Addition Curing Silicone rubber that foams to up to 7 times its original volume, is now serving a growing range of new energy applications — from cell cushioning pads to pack insulation layers.

The flame retardancy of HONG YE SILICONE's Foamed Silicone adds a critical safety margin in thermal runaway scenarios, while its wide service temperature range of -65°C to 200°C keeps performance stable through every phase of charging and discharging. Unlike conventional polyurethane foams, the closed-cell structure resists electrolytes and moisture, preventing the degradation that shortens battery life. The uniform cell distribution and high rebound ensure consistent cushioning through millions of compression cycles.

The material's 2× to 7× expansion ratio reduces raw material consumption, directly lowering the cost per protection component — a decisive advantage in an industry where every gram and every cent is measured. The simple 1:1 mixing ratio and room-temperature or heat curing make the foam compatible with both manual pouring and automated dispensing lines, supporting the high-volume production that battery manufacturers require.

Beyond battery packs, the foam seals door and window channels, cushions motor systems, and protects the sensitive electronics of charging stations exposed to UV, rain, and temperature extremes. With ISO9001-certified quality control, UL and CE compliance, and delivery to buyers in more than 138 countries, HONG YE SILICONE provides new energy manufacturers with a reliable, certifiable material for the components that protect the batteries powering the electric future.
