The difference between flame retardant silicone hose and other silicone hose when burning
The flame-retardant silicone hose and other silicone tubings were compared and found to have excellent flame retardancy, ignition point, and flame height after incineration. Although the third-party test report uses the products produced in practice.In order to eliminate the doubts of many customers, the fire-retardant silicone tubing and other silicone hoses are prepared for the product from the workshop. These tests are very simple and can be tested anywhere. First of all, you need to prepare to imitate a stable open flame source. It is recommended to use an alcohol lamp. This is a more reasonable testing device, and the test results of the lighter are not stable. The flame-retardant silicone tubing and other silicone hoses can be burned together on an alcohol lamp, and use the visible detection method will feel at ease, and analyze the two sets of different products from the three angles of ignition point, incineration time, and after incineration. The difference of the actual results and the respective incineration time will be clearly distinguished.
Ignition point: Put the flame-retardant silicone tubing in the outer flame of an alcohol lamp at 500~600° and burn (flame is divided into outer flame, inner flame, and flame core). The ignition point is 50~80 minutes through our company's flame-retardant silicone tubing, and other non-flame retardant silicone tubings will be incinerated when they are put into the outer flame for about 30 minutes. From this, the ignition point of the flame retardant silicone hose is more than twice as high as the instantaneous ignition point is as high as 1000°. Even above, the current incineration temperature of household electrical appliances is basically below 1000°, so the flame-retardant silicone hose used in daily life is almost not burned instantly. Other silicone tubings have a low ignition point, and will be ignited or even expand the flame after encountering an open flame, along with dense smoke. Burning moment: Generally ordinary silicone tubing will accelerate and expand the height of the flame and the burning area during incineration. It does not have the flame retardant effect. Just like other ordinary materials, ordinary silicone tubing will burn automatically after removing the fire source. For a period of time, it was about 20 minutes to extinguish (parallel burning). After careful observation, it was found that scattered flames were found in the ashes of the silicone hose and then it quelled. Through the incineration test, it can be clearly observed that the flame-retardant silicone tubing will not disperse and expand the flame after being ignited by an open flame. If it is removed from the fire source, it can be extinguished within 3 minutes without flames and sparks. The ashes do not produce flames, so they can extinguish the scattered flames autonomously. After incineration: The extruded silica gel product will appear white solid powder after incineration. The temperature inside the tube is high after incineration, and there will be sparks that cannot achieve rapid and autonomous distinguish. The flame can be completely distinguished within a few seconds. Therefore, ordinary silicone hoses cannot play a flame-retardant effect in household appliances, and flame-retardant silicone hoses can effectively control the speed of flame dispersion and have a good self-distinguish effect. Since the ignition point of silica gel itself is relatively high compared with other materials, even ordinary silicone hoses are better than other materials in terms of incineration speed and ignition point compared with other materials. Flame retardant silicone tubings use a special material of silica gel specially developed for protection against incineration. Its function is well known. The above test data is obtained from the test of material data. Each data will have a slight discrepancy. The addition of flame retardants and the choice of materials will affect the final trend.
