Silicone sealant:
Silicone is a polymer material with sO chain links as the main chain
 >Excellent high and low temperature resistance (60-260°C)
 >Good weather resistance
>Electrical insulation (volume resistivity up to 1×101416gcm)
 >After curing, it is an elastomer, which has good shock and impact resistance.
 >The thermal conductivity reaches 0203Wm·K (air is 0.023Wm·K), and the thermal conductivity can be greatly improved after adding thermal conductive filler.
 >Flame-retardant good combustion temperature is about 430 ° ° C, flame temperature reaches 750 ° C, sio2 is produced after combustion, no corrosive gas, after adding flame retardant filler can reach ∨-0 flame retardant level Test method: sample is carried out twice 10 Seconds of the burning test, the flame is extinguished within 30 seconds without burning matter. When a battery core is on fire, it can block the surrounding battery from igniting.
>Water vapor transmission rate is good. PAcK sealed by silicone sealant can pass the P67 waterproof test test method: the sealed PAcK is completely immersed in the water tank, and the top is separated from the water surface by 015-1m for 30 minutes, the performance is unchanged. No water enters the interior of PAcK. Can effectively prevent water vapor from penetrating the battery
 >The thermal conductivity is good, the thermal conductivity reaches 020.3Wm·K (the air is 0.023Wm·K), and the thermal conductivity can be greatly improved after the addition of the thermal conductive filler, which can effectively transfer the heat generated inside the battery to the surface, reduce the heat accumulation and improve the battery life. Silicone sealant has excellent performance, can meet the requirements of shockproof, waterproof, flame retardant and conductive of power battery, can meet the use of automobile under different climatic conditions, and effectively improve the safety of power battery.
