What is the difference between flame retardant sealant and fireproof sealing?

Flame retardant and fireproof sealing have different performance requirements. Stopping burning after leaving the fire source does not mean that the sealing material can maintain sealing integrity under sustained fire conditions.

Therefore, the product cannot be used as a fireproof sealing material just based on the name “flame retardant”. This article introduces the differences between the two and demonstrates Glorystar DJ-A3-GS999 fireproof sealant.
