Ecological composite Mgo wheat straw board is the only artificial board not releasing formaldehyde at present! It is a kind of new-type ecological and environmental protection artificial board. The main raw material is wheat, straw and other crops straw, which come from nature. The adhesive is professional ecological gum not containing formaldehyde, and the boards are researched and produced with proprietary technology. They possess the advant ages of woody shaving boards and medium density fiberboards. It can be widely used as interior decoration, furniture producing, floor, cabinet, acoustic board, word pad, drawing board and packaging materials, they are ideal substitute products of woody artificial boards.

The contrast of the performances of various composite boards:

Ecological composite wheat straw board	Calcium silicate board	Gypsum board
The weight is light, and it doesn’t require much about carina bearing, and the whole project cost is low	The weight is heavy, and it requires much about carina bearing, and the whole project cost is high.	The weight is heavy, and it requires much about carina bearing, and the whole project cost is high
The thickness of 3mm can reach the demand of A – level fireproof incombustible materials	The thickness of 6mm can jus t reach the Demand of A- level fireproof incombustible materials	The thickness of 12mm can just reach the demand of A-level fireproof incombustible materials
Excellent humidity - resistance, not deformed, not getting damp.	The expansion coefficient is about 8/10000, and water absorption is a little higher (water absorption is 35%)	Strong water absorption, easy to expand and become deformed, easy to delaminate when the principal planes bond gypsum boards.
Light weight, convenient carrying, low ratio of damage , waterproof ,dame proof.	Most products contain asbestos, high ratio of damage , not waterproof, not dame proof.	Low intensity, bad weather res is tance, afraid of collision, water and moisture, serious deformation when soaking in the water.
The products can be secondary manufactured with various panels , exterior decorating surface or thick wood veneers, strong adhesive force, and they can be stuck with ceramic tiles, plastering and spraying paint.	They can’t be secondary manufactured wit h various panels, exterior decorating surface or thick wood veneers on the whole, weak adhesive force	They are difficult To be secondary manufactured, weak surface cohesion, they can ’ t be stuck with ceramic tiles.
