YUNZHI fireproof aluminum composite panel is a new type of high-grade fireproof material for wall decoration. It is a new type of metal plastic composite material, which is composed of coated aluminum plate and special flame retardant modified polyethylene plastic core material by hot pressing with polymer adhesive film (or hot melt adhesive).
YUNZHI fireproof aluminum composite panel is a new type of high-grade fireproof material for wall decoration. It is a new type of metal plastic composite material, which is composed of coated aluminum plate and special flame retardant modified polyethylene plastic core material by hot pressing with polymer adhesive film (or hot melt adhesive). Due to its elegant appearance, beautiful fashion, fire protection and environmental protection, convenient construction and other advantages, it is considered that the new high-grade decorative materials for modern curtain wall decoration have a bright future.
There are 2 kinds of fireproof aluminum composite panel, B1 class and A2 class.
For B1 class fireproof aluminum composite panel, it contains: 55% - 55% flame retardant, the main ingredients are aluminum oxide (Al?O?) and magnesium oxide (MgO); When B1 grade panels are put on fire, it can be catched on fire after 5 minutes, and when the fire leave the panels, the fire on the panels will extinguish after 10 seconds.
For A2 class fireproof aluminum composite panel, it Contains 88% - 90% of the flame retardant,the main ingredients are aluminium hydroxide (Al(OH)3) and magnesium hydroxide (Mg(OH)2); it can be catched on fire after 20 minutes, and the fire will extinguish at once when the fire leave the panels.

It is suitable for
1. Exterior wall of building, Curtain wall
2. Refitting or renovating of old building exterior wall.
3. The balcony, equipment unit, interior compartments
4. Panel, logo plate, display platform.
5. The interior wall decoration panel, ceiling, advertising board
6. Industrial usage, cold car body etc..
1. has excellent fire resistance and flame retardant, and its combustion performance is not lower than B1 level;
2. Superior peel strength and good mechanical properties;
3. The core material process has strong adaptability, almost does not change the extrusion processing conditions of ordinary aluminum composite panel, which can meet the technical route requirements of different aluminum-plastic plate manufacturing processes
4. The core material has excellent thermal oxygen aging property and can withstand high and low temperature - 40℃- + 80℃for 20 cycles without change;
5. The flame retardant contained in the core material has good stability, no migration and precipitation, and good weather resistance, which overcomes the defects of ordinary halogen flame retardants that are not resistant to ultraviolet light, so it is very suitable for indoor and outdoor architectural decoration;
6. The core material is environment-friendly flame retardant and clean material, halogen-free and low smoke. It is extremely difficult to burn. The smoke volume is very small when burning, and there is no corrosive gas and black smoke. It is pollution-free and meets the requirements of the state for green building materials and environmental protection.
