Foamed silicone tube is made of high temperature silicone foam. The foamed silicone tube has high temperature resistance, good elasticity and can be operated at high temperature. At the same time, it has excellent aging resistance and weather resistance, and is an ideal material for heat preservation and heat insulation.
Silicone foam tube is a common pipe protection material, because of its good low and high temperature resistance, waterproof, insulation corrosion resistance and other characteristics, is widely used in construction, power, equipment and so on. However, the occurrence of life fire during actual use is one of the inevitable risks.
Therefore, many people will be concerned about whether the silicone foam tube has fire-retardant properties to ensure that it will not become fuel in the event of a fire.
The fire resistance of silicone foam tube mainly depends on its ingredients and manufacturing process. Under normal circumstances, the silicone foam tube will add some flame retardants to put forward high flame retardant properties, the foam structure of the silicone foam tube usually uses azodimethylamide, azodiisobutyrate as a foaming agent after vulcanization foaming, can also play a certain role in fire resistance. When the silicone foam tube encounters the heat radiation from the fire source, the foam structure on the surface will melt in a short time, forming a dense carbonized layer to block the flame before further burning. According to the international standard UL94, the fire protection grade of the silicone foam tube is generally V-0 or V-1, which means that the silicone foam tube burning flame under the action of the flame and will be automatically extinguished after the fire source is removed, so as to effectively prevent the occurrence of fire.
The fire performance of silicone foam tube is also affected by uncontrollable factors such as the use environment, temperature, humidity, etc. Disintegration, expansion, combustion and other conditions lead to the occurrence of fire. Therefore, in the specific use process need to choose according to the actual situation in line with the fire standards of the product, silicone foam tube has a certain fire performance, can prevent the occurrence of fire, but also need to pay attention to the use of environmental and other factors. Therefore, choose products that meet fire protection standards during use, and take appropriate fire prevention measures to ensure safety.
