What about the fireproofing grade of he homogeneous vinyl ?

In my country, the flammability of flooring material is divided into the following grades, A grade: non-ignitable flooring, B1: difficult to ignite  flooring, B2: ignitable flooring, B3 Grade: It is easy to ignite the flooring , through these conditions to judge the anti-ignition level of the flooring material!

As an important part of the room, the floor should have the characteristics of fire prevention and flame retardant. Generally speaking, in the flooring market, PVC vinyl flooring has this feature. However, there are many kinds of vinyl flooring on the market at present,the homogeneous vinyl flooring that is often mentioned has the properties of fire resistance and not easy to ignite, and its fire resistance can reach B1 level. What is the fire resistance of this building material?

The pvc vinyl flooring can be divided into the following categories of standards (belonging to the material) of the combustion performance (building performance): (1) Class A: Non-combustible building materials that produce almost no flammable substances. (2) b1: Materials that are difficult to ignite, materials that are difficult to ignite, and have or meet resistance at high temperatures, they are not easy to spread rapidly in the middle of the fire source, and the ignition stops quickly when the fire source leaves. (3) b2: Combustible building materials, materials that can be ignited or have daily luminous properties, will immediately catch fire and burn products when exposed to a fire source at high temperature, which is easy to cause fire, such as wood, wood stairwells, wood beams, Wooden frame, etc.

From the above analysis, we can clearly see that the fire protection standard of good quality homogeneous vinyl flooring can reach B1 level, and its protective performance is second only to stone. The homogeneous vinyl floor itself is not easy to burn, and it can also prevent burning. The smoke produced by the homogeneous vinyl flooring will not cause harm to the human body, nor will it produce suffocating toxic and harmful gases.
