Flame-Retardant Foamed Silicone for EV Battery Safety

Product Overview

This battery protection foamed silicone is engineered for the harsh operating environment inside EV and energy-storage battery packs: vibration, shock, temperature swings and fire risk. The elastic closed-cell structure of liquid silicone Foam absorbs road vibration and impact to protect battery cells, while the flame-retardant silicone matrix slows heat propagation and reduces fire risk in extreme conditions. Different from polyurethane foam that burns easily and absorbs moisture, this low-water-absorption Foam Silicone keeps stable cushioning and electrical insulation over the full battery life. With adjustable density and hardness, this RTV Silicone Foam fills gaps between cells and modules precisely, making it an essential safety Foaming Silicone Rubber for modern energy storage systems.

Core Product Features & Advantages

1. Vibration and impact protection: Elastic Silicone Sponge absorbs road shock and mechanical impact around battery modules.
2. Flame retardancy: Fire-safe Foamed Silicone slows heat spread and supports battery pack safety design.
3. Electrical insulation: Insulating Liquid Silicone Foam prevents short circuits between cells and busbars.
4. Low water absorption: Closed-cell Foam Silicone resists moisture ingress inside sealed battery enclosures.
5. Precise gap filling: Soft RTV Silicone Foam fills cell and module gaps to reduce movement and wear.
6. Long battery-life support: Stable Foaming Silicone Rubber keeps protective performance over years of charging cycles.

Step-by-Step Usage Instructions

1. Component stirring: Stir the two parts of Liquid Silicone evenly for a uniform protective foaming structure.
2. Ratio mixing: Blend at 1:1 for about 3 minutes to build a consistent flame-retardant Foaming Silicone network.
3. Vacuum de-airing: De-gas to refine cell uniformity and insulation quality of the Silicone Sponge.
4. Mold forming: Shape cushioning pads with Mold Silicone tooling and cure to finished Foamed Silicone parts.

Application

Scenarios Battery module cushioning pads and cell gap fillers, pack bottom and side impact protection, busbar and junction box insulation, energy-storage cabinet padding and charging equipment protective layers. This high-stability Foamed Silicone provides reliable safety protection for electric vehicles and energy-storage systems.

Precautions

Avoid contact with cure-inhibiting substances such as nitrogen, sulfur, phosphorus, tin, lead, cadmium and mercury; keep away from direct sunlight and high-temperature baking before curing.

Packaging & Storage

25 kg sealed drums, stored dry and cool with lids closed to preserve protective foaming performance; shipped as non-hazardous cargo.
