720 type fire retardant package

Fireproof bags are mostly used for fire-proof sealing of cable penetration holes in power plants, industrial and mining enterprises, high-rise buildings, petrochemicals, etc., and are suitable for occasions where cables need to be frequently replaced or added or removed or temporary fire protection measures in construction projects.

The fireproof bag is an outer bag sewn with glass fiber cloth and filled with convenient fire-retardant fuel such as perlite and fireproof mud.The fireproof bag has the function of fireproof and flame retardant, which can resist fire for more than 4 hours, expand and solidify at higher temperature.

It forms a heat-insulating, smoke-proof seal, and has good fire and moisture resistance.The main technical performance is at the level of similar foreign products,

It is suitable for blocking the voids formed when cables, air pipes, air pipes, metal pipes and other penetrating objects pass through partition walls or barriers in electricity, telecommunications, postal, chemical, industrial and mining, enterprises, and buildings.It can prevent the flame from spreading, and is suitable for frequent replacement of important parts of the cable.It can prevent the fire from spreading along the cable, and avoid the loss of life and property to a great extent.The product has the characteristics of good ventilation and air permeability, acid and alkali resistance, water resistance, oil resistance, light weight, and convenient use at room temperature. When it is exposed to fire, it expands and carbonizes to form a fire barrier of thickness and strength, and absorbs heat and releases during the expansion and carbonization process. Non-combustible gas has the purpose of preventing fire, heat insulation and smoke. It is an ideal product for fire protection and flame retardancy of power cables.
