In the field of building insulation, rubber insulation boards are highly favored for their excellent insulation performance and environmental characteristics. Among them, the B1 level flame retardant standard is an important indicator for measuring the fire resistance performance of rubber insulation boards.

The B1 level flame retardant standard means that rubber insulation boards have good flame retardancy. Specifically, in flame spread testing, when tested according to the testing methods specified in relevant standards, the flame spread distance of rubber insulation boards should meet the corresponding limit requirements. Generally speaking, this type of insulation board burns relatively slowly after being ignited by an open flame and can self extinguish after a certain period of time, without continuing to burn and rapidly spreading the fire.

The composition and structure of the material itself play a key role in achieving B1 level flame retardant standards for rubber insulation boards. Usually, it will add some flame retardant additives during the production process, such as phosphorus based flame retardants, nitrogen based flame retardants, etc. These additives can decompose at high temperatures and produce non flammable substances, thereby playing a role in flame retardancy. At the same time, the tight structure of the rubber insulation board also helps to prevent the entry of oxygen and the transfer of heat, further improving its flame retardant performance.

In practical applications, the advantages of B1 grade rubber insulation board are obvious. On the one hand, it can effectively ensure the safety of buildings. In the event of a fire, this insulation material can slow down the spread of the fire, buy more time for personnel evacuation and firefighting, reduce property damage and casualties. On the other hand, it also meets the fire prevention requirements and environmental standards of modern buildings, which can improve the fire safety of buildings while ensuring the insulation effect.

In order to ensure that the rubber insulation board truly meets the B1 level flame retardant standard, strict quality testing and supervision are required during production and use. Production enterprises should control their production processes in accordance with relevant standards and specifications to ensure stable and reliable product quality; When selecting and installing rubber insulation boards, users should also choose products that meet the B1 level flame retardant standard, and follow the correct installation method for construction to fully utilize their flame retardant properties.
