According to the GB 8624-2012 standard, building materials and products are classified according to their combustion performance. Generally, building materials are divided into four levels: A, B1, B2, and B3. Polycarbonate is used as a Class B1 fireproof material. Non-flammable, and self-extinguishing away from the fire. Poycarbonate will not produce toxic gas when burned, and will not promote the spread
of flames. It is a good environmentally friendly building material.
Class A: Non-combustible building materials, materials that hardly burn.
Class B1: Flame-retardant building materials: Flame-retardant materials have a good flame retardant effect. It is difficult to catch fire in the air or under the action of high temperature, and it is not easy to spread quickly, and the combustion stops immediately when the fire source is removed.
Class B2: Flammable building materials: Flammable materials have a certain flame retardant effect. When exposed to an open flame in the air or under the action of high temperature, it will catch fire immediately, which will easily lead to the spread of fire, such as wooden pillars, wooden roof trusses, wooden beams, wooden stairs, etc.
Class B3: Flammable building materials, without any flame retardant effect, extremely flammable, and high fire risk
Polycarbonate material as a B1 fireproof material, represents that polycarbonate sheet is a flame-retardant material, which allows customers to have more space when choosing fireproof materials. At the same time, polycarbonate sheet has the characteristics of more impact resistance and scratch resistance, so that it can play a greater role in construction.
The Polycarbonate is self-extinguishing away from the fire, and will not produce toxic gas when burned, and will not promote the spread of flames. It is a good environmentally friendly building material.
For some buildings, fire and flame retardancy of building materials are very important conditions. Many customers will choose PC endurance board engineering endurance board as a building material.
