Class A Fire Rated Plywood

Class a fire rated plywood, also known as flame-retardant plywood, has a moisture content index of 6% to 14%. It is made by treating wood with certain flame retardants, fireproof agents, etc., making the board a difficult-to-burn material. This enables it to self-extinguish when exposed to small fires and delay or slow down the time for extinguishing fires that have been burned and aged in case of large fires.The following are some standards for fire resistance grades: Grade A class a fire rated plywood belongs to non-combustible materials and has the highest fire resistance performance. This grade of class a fire rated plywood hardly burns in A fire and does not produce toxic or harmful smoke. However, due to the extremely high production technology and material requirements of A-grade class a fire rated plywood plywood, its price is also relatively expensive. B1 grade class a fire rated plywood is a flame-retardant material and is commonly used in the decoration of high-end public places. Although this type of board can burn in a fire, its burning speed is relatively slow and it does not produce a large amount of toxic smoke during the burning process, thus achieving a certain fireproof and flame-retardant effect.Grade B2 class a fire rated plywood is a non-flammable material, but it can still burn under certain conditions. Its fire resistance is relatively low, but it still has certain applications in the decoration and renovation of mid-to-low-end public places.Grade B3 class a fire rated plywood is actually a flammable material with no flame-retardant effect at all. It is highly flammable and poses a significant fire hazard.
