What is flame retardant plywood?

Flame retardant plywood is a flame retardant board, also known as flame retardant board, which is a kind of decoration material. It has many flame retardant grades. When a fire occurs, flame retardant plywood can suppress open flames, reduce heat, and buy time for people to escape. effect.

Flame retardant plywood is a three-layer or multi-layer board material that is made of wood segments into veneers or sliced ​​into veneers, and the veneers are flame-retardant and then glued with adhesives. veneer, and the fiber directions of adjacent layers of veneers are glued perpendicular to each other.

The role of flame retardant plywood:

  • Flame-retardant plywood is weather-resistant, boiling water-resistant and flame-retardant plywood, which has the advantages of durability, high temperature resistance, and steam treatment.
  • Fire-retardant plywood is water-resistant fire-retardant plywood, which can be dipped in cold water and dipped in hot water for a short time.
  • Flame-retardant plywood is moisture-resistant and flame-retardant plywood, which can be dipped in cold water for a short time and is suitable for indoor use at room temperature. For furniture and general construction purposes.
  • Flame-retardant plywood is not moisture-resistant flame-retardant plywood, which is used in indoor conditions.

What are the fire ratings of flame retardant plywood?

Flame-retardant plywood is produced with wood as the main raw material. Due to its rational structure and fine processing in the production process, it can generally overcome the defects of wood and greatly improve and improve the physical and mechanical properties of wood. At the same time, flame-retardant plywood also It overcomes the shortcoming of ordinary plywood that is easy to burn, and effectively improves the flame-retardant performance of plywood. The production of flame-retardant plywood is an important method to fully and reasonably utilize wood and improve the performance of wood. The smoke density and toxic gas indicators for fire hazard are fully considered.

Excellent product properties of flame retardant plywood:

①Excellent flame retardant performance:

GB8624-2006 “Classification of Combustion Performance of Building Materials and Products” Class B

GB/T8625-2005 “Test method for flame retardancy of building materials” flame retardant materials

②The release of free formaldehyde from the product is less than or equal to 4.0mg/100g, which is far lower than the national standard E1 level of 9.0mg/100g;

③The hygroscopicity of flame-retardant plywood is not large, the expansion rate of water absorption thickness is stable, and the moisture-proof performance is excellent, and it does not affect the secondary processing such as veneer and paint;

④It has high chemical stability and excellent aging resistance;

⑤MOR, MOE, IB and other physical and mechanical performance indicators all meet the requirements of the national standard for high-quality products;

⑥ Flame retardant plywood itself is safe and environmentally friendly, and the burning residue is non-toxic and non-polluting;

⑦ Flame retardant plywood has excellent screw holding power and does not corrode metal links;

⑧ Does not damage the finish, adhesiveness and machinability of flame retardant plywood;

⑨ Anti-mildew treatment can be carried out according to customer requirements;

Fire rating classification of flame retardant plywood:

Class A fire rating: Class A is a non-combustible material, and the flame retardant rating of Class A is very high, and the price is quite expensive.

Fire rating class B: Class B flame retardant class is a flame retardant material. Generally, high-end public places are decorated with this material.

Fire rating B1: B1 is a non-flammable material, it is flammable, but it is not easy to burn, and it has a certain fireproof effect in terms of fire resistance. This kind of board is generally used in low-end public places.
