Since the battery pack of new energy vehicles is placed on the chassis of vehicle, there are many opportunities to contact the environment and rainwater, while it needs to be disassembled and used for a long time. TY-640 is a medium-hardness silicone foam product developed and produced according to the application needs of battery sealing of new energy vehicles, and has passed a full range of customer application tests and market inspections.
