As a special daily necessities-leather products, it is used more and more widely, from the initial simple wearing to high-end consumption. Today, leather has been used in the field of flame retardants. For example, the decoration in airplanes, trains, and automobiles is closely related to people's lives and property. The leather used in these places requires certain flame retardancy, so improving the fire resistance of leather products will be a new study. Below, I will share with you some small methods to better evaluate the fire resistance of leather flame retardants.

The methods for evaluating leather flame retardants are mainly vertical combustion test method and aerobic index test method. Although these two methods have some limitations, they are still a small method with high credibility. The specific test method of the vertical combustion test method is to refer to the American Leather Chemist's Standard for Fire Resistance. In other words, it is a kind of ignited combustion test, which aims to measure the flame extinguishment required when the combustion source is removed Time and the time it takes for the embers to completely extinguish. At the same time, it can also measure the remaining length and weight loss of the sample after combustion. Regarding the data, the smaller the parameter value, the better the fire resistance of the leather flame retardant. China's flame retardant industry is in a period of restructuring and transformation of production structure. Some flame retardants will withdraw from the stage of history; another part will be replaced by new flame retardants. Large-scale use.
