What is A2-grade composite flame-retardant board? 01
Flame-retardant plywood (also known as fire-retardant board or flame-retardant plywood) is typically made by rotary cutting logs into wood chips or planing timber into small blocks, treating the wood chips with flame retardant, and then gluing them together with adhesives. It is usually made with an odd number of layers of wood chips, with the fiber directions of adjacent layers perpendicular to each other. It possesses five major properties: flame retardancy, smoke suppression, corrosion resistance, insect resistance, and stability. These properties make flame-retardant plywood widely used in large-scale engineering projects. As a flame-retardant material, flame-retardant plywood can be classified into four grades: A, B1, B2, and B3, with Grade A being non-combustible and exhibiting the best flame-retardant performance.
What are the advantages of TBB A2 grade composite flame-retardant boards? 02
TBB composite flame retardant board uses modified magnesium oxide board as the base material and modified inorganic adhesive to bond fire retardant wood veneer to the surface. The product achieves an A2 non-combustible rating. At the same time, the wood surface gives the product the advantages of easy bonding with other materials and high bonding strength. It also has the advantages of humidity regulation and less condensation on the surface.
Reason 03 for choosing TBB A2 grade composite flame retardant board
① Fire Safety: Class A fire-retardant boards effectively suppress the spread of fire, and the magnesium oxide board substrate, as an inorganic material, is extremely difficult to burn and does not easily produce harmful gases. This buys precious time for escape, reduces fire damage, and protects life and property.
② Environmental performance: The formaldehyde emission of Class A fire-retardant boards is strictly controlled during the production process, reaching the new national standard E0 level, which is superior to the national standard and is environmentally friendly.
③ Thermal insulation performance: Class A fire-retardant boards have a high-efficiency thermal insulation effect, which can prevent the high temperature air at the fire scene from causing harm to the human body.
Application Scenarios 04 of TBB A2 Grade Flame Retardant Board
A2-grade flame-retardant boards are now widely used in the decoration of various public places, high-speed train carriages, stadiums, civil buildings, industrial buildings, conference centers, entertainment venues, schools, hospitals, etc., where strict fire prevention and flame retardancy requirements are required. Most flame-retardant boards on the market are B2-grade, which offer almost no flame-retardant effect in the event of a fire. We frequently see news reports of high-rise building fires across the country. Due to the complex ignition factors, multiple and rapid fire spread routes, difficulties in safe evacuation, and the challenges of firefighting, fires often result in huge casualties and property losses. Using flame-retardant boards that truly achieve B1 or even A-grade flame-retardant effects would undoubtedly provide more escape time and space. Therefore, A-grade composite flame-retardant boards will inevitably be the future trend in engineering fire protection materials, and TBB will continue to launch high-quality products that meet engineering needs.
