The panel comprises a polyethylene core between two aluminum skin, the LDPE core's thickness and alloy's width can be designed according to customers requirment, the front surface can be used the PVDF, Polyester and Nanometer paints, the protective film on the top surface can be peeled off. The back sheet is done by anti-corrosive pretreament or coated with anti-corrosive paints.
The content of sandwiched core is Mg(OH)² NaOH and PE mixture materials, we use the high efficiency Dopont's Coupling
Agent, the materials not only have the fire proof proterty, but also easy for formation.

Fire proof property :
When there is fire accident, and the temperature reaches 340-490° C, the Mg(OH)² will break up and have chemical reaction.
The reaction equation is :
Mg(OH)² - MgO + H20.
the Mg(OH)² doesn't generated any harmuful matter in the whole bruning process, the generated materials can absorb the toxic gas and smoke.
The H2O can dilute the Oxygen one the surface of the fire materials, the actived Mg0(can bear the temperature in 2000°C) not only can absorb the melting remain materials but also abated the smoke and stop the melting drop,which is a new kind of environmentfriendly fire retardant materials.
Process properties :
We use the high efficiency Dopont's Coupling Agent, it can be melted tightly with inorganic substances. The Fire Proof panels can reach all the normal plastic cores process properties.

♦ MIRROR FINISH
The front surface of the sheet is processed by chemical anodizing treatment, the high reflection makes the surface like a mirror effect, the back side of the sheet is made by anti-corrosive alloy skin.
Main usage Interior decoration, especially used in roof cladding, kitchen cookers, home facili-ties, furniture and so on.

Product's advangtages :
Light weight, high tensile strength, high hardness, good flatness, fashion, modem,easy installation and easy maintenance.
