This material is an ammonium phosphate-based semi-rigid expansion material. After expansion, the product can produce a good flexible foam insulation layer, and the pressure generated during expansion is low. It is suitable for heat insulation protection of fireproof door locks and hardware, and can also be used for fireproof sealing around glass.
