With the rapid development of the new energy vehicle industry, organic silicon materials are playing an increasingly important role in this field. Especially in key areas such as battery safety, body sealing, and cable protection, the excellent performance of organic silicon materials provides strong guarantees for the safety performance of new energy vehicles.
In terms of battery safety, organic silicon materials are widely used for sealing and protection of battery packs. The silicone sealant developed by a leading enterprise has excellent flame retardancy and thermal conductivity, which can effectively delay the spread of fire in case of thermal runaway of the battery, and buy valuable time for passengers to escape. This material has passed UL94 V-0 certification and has been applied in multiple mainstream car companies.

Vehicle body sealing is another important application area. Organic silicone sealant, with its excellent weather resistance and elasticity, can effectively prevent moisture and dust from entering, ensuring the cleanliness and safety of the car interior environment. After adopting a new type of silicone sealant, the air tightness of a new energy vehicle model of a joint venture brand has been improved by 30%, and the interior noise has been reduced by 2 decibels.
In terms of cable protection, organic silicon materials also show great potential. The high-voltage wiring harness of new energy vehicles has higher requirements for insulation materials, and organic silicon insulation materials have become an ideal choice due to their high temperature resistance and aging resistance. The silicone insulation material developed by a certain supplier can be used for a long time at a high temperature of 200 ℃, greatly improving the safety and reliability of cables.
Technological innovation is the key to driving applications. The nano modified organic silicon material developed by a certain research team has increased the thermal conductivity by 50%, providing a new solution for battery thermal management. This material has applied for multiple invention patents and is expected to achieve mass production next year.
