1.Block the flame: effectively prevent the spread of fire, to ensure the safety of personnel and property;

2.Blocking Smoke: effectively prevent the spread of smoke, to protect personnel, equipment from the threat of smoke;

3.Block Heat: effectively prevent heat conduction caused by the back of the spontaneous combustion, thereby preventing the spread of fire;

4.Water tightness: with water tightness, to achieve effective waterproof function;

5.Anti-ablation: in case of fire, the whole structure can be kept intact without collapse;

6.Anti-high-pressure water gun impact: can resist the impact of high-pressure fire water gun to ensure the safety of fire fighters and backfire division;

7.Explosion-proof: it can resist the explosion shock caused by electric fire;

8.Weathering: the fire- proof sealing system can remain effective for a long time before a fire occurs
