Because the fire prevention of ecological wood, waterproof, insect control, formaldehyde and decorative effect beautiful characteristics are also applied in a few specific areas. So do you know the fire rating of eco wood. Commonly used building materials are classified into four grades: B3, B2, B1 and A. Class B3 is flammable building material, class B2 is combustible building material, class B1 is nonflammable building material, and Class A is nonflammable building material.
And the fire protection grade of ecological wood products can reach B1 level. So why is that? Because eco-wood products are produced by wood powder, pvc, calcium powder, toner, stabilizer,
blowing agent and other components through thermoplastic extrusion, and the main component of eco-wood is wood powder, and wood powder is combustible material. So even if the product added a large number of stabilizers and other non-combustible materials, eco-wood combustion grade can only reach B1.
