MGO flooring core board is a kind of high-density inorganic material made of magnesium oxide and magnesium sulfate as the main raw materials, adding perlite, bamboo powder and high-strength fiberglass cloth.
It has the characteristics of A1 class fire protection, good flatness, dimension stable and environmental protection, and specialized used as the core material of composite floor.
Features1. Fire and water resistance
Class A1 fireproof, non combustible, smoke free and non-toxic, and not expand and deform after absorbing water.
2. Durable
High surface bonding strength and internal bonding strength, dimension stable, high and no obvious warpage in high and low temperature
3. Green environmental protection
Zero formaldehyde, no heavy metal, recyclable and renewable, damp-proof and anti halogen.
