FJ fireproof sealant is a gray and black colloid with strong adhesion. When facing fire or high temperature, it will be quickly expanded to 10 times as the original volume to form a good insulating porous media. The sealants can be filled at both ends of the device, forming elastomeric after curing, and play the role of fire prevention and sealing.
