The difference between flame-retardant silicone tubing and other silicone tubing during combustion

  After comparing the flame-retardant silicone tube with other silicone tubes, it was found that its flame-retardant effect, ignition point, and flame height after combustion are all excellent. Although the third-party test report is the core, the actual product used by the user is the only one. In order to eliminate the doubts in the minds of many customers, the products that are finally shipped have specially prepared a comparison of the ignition point of the flame-retardant silicone tube and other silicone tubes. These tests are very simple and can be tested anywhere.
  First of all, it is necessary to prepare to simulate a stable flame source. It is recommended to use an alcohol lamp, which is a more reasonable detection equipment, but the test results of the lighter are not stable and can not be used. The flame-retardant silicone tube and other silicone tubes can be burned on the alcohol lamp at the same time, and the user will feel at ease with the detection method visible to the naked eye. The analysis of two groups of different products starts from the three angles of ignition point, burning time, and after burning. The difference between the actual result and the respective burning time will be clearly distinguished.
  Ignition point: Put the flame-retardant silicone tube in the outer flame of the alcohol lamp at 500~600° to burn (the flame is divided into outer flame, inner flame, and flame core). After the physical inspection of our flame-retardant silicone tube products, the ignition time is 50~80m The other non-flame-retardant silicone tubes will be burned when thrown into the outer flame for about 30m. From the actual test time, it is known that the ignition point of the flame-retardant silicone tube is more than twice that, and the instantaneous ignition point is as high as 1000° Even above, the combustion temperature of household electrical appliances is basically below 1000°C, so flame-retardant silicone tubes used in daily life will hardly burn instantly.
The flame-retardant silicone tube has a high ignition point and is difficult to ignite (as shown in the figure below).

Other silicone tubes have a low ignition point and will be ignited or even expand the flame after encountering an open flame, accompanied by thick smoke (as shown in the figure below)
  Burning time: Ordinary silicone tubes will accelerate and expand the height of the flame and the burning area during combustion. They do not have the flame retardant effect. Just like other ordinary materials, ordinary silicone tubes will burn automatically after they are removed from the fire source. How can it last for about 20m for a period of time before it can be extinguished (parallel burning), after careful observation, it is found that sporadic flames can be found in the ashes of the silicone tube and then extinguished. Through the actual combustion test, it can be clearly observed that the flame-retardant silicone tube will not spread and expand the flame after it is ignited by an open flame. It can be extinguished within 3m without flames and spark ash when it is removed from the fire source. It also does not produce flames, so it can independently extinguish sporadic flames.
The flame-retardant silicone tube will not burn even if it is ignited, and it can have the effect of self-extinguishing after removing the fire source (as shown in the figure below).

Generally, other silicone tubes will expand the height and width of the fire source after burning, and will not automatically extinguish (as shown in the figure below) )
  After burning: Extruded silicone products will appear as white solid powder after burning. Ordinary silicone tubes will have a higher internal temperature after burning. There may even be sparks that cannot achieve rapid self-extinguishing and need to be completely extinguished within a few seconds. , so ordinary silicone tubes cannot play a flame-retardant role in household appliances, but flame-retardant silicone tubes can effectively control the speed of flame diffusion and have a good self-extinguishing effect.
  Because the ignition point of silicone itself is relatively high compared to other materials, even ordinary silicone tubes are better than other materials in terms of burning speed and ignition point. Flame-retardant silicone tubes It is a silicone special material specially developed for protection against combustion, and its effect is obvious to all. The above test data are obtained from physical material tests. Each company's data will have slight discrepancies. The addition of flame retardants and the selection of materials will affect the final trend.
