There are many kinds of methods to test the flame retardancy, almost all countries have their own national standards. Different kinds of fabrics have different test methods, and some fabrics can be evaluated by different test methods.
According to the different placement of fabric samples, it can be divided into vertical method, inclined method (45°) and horizontal method. According to the different light source, it can be divided into propane and butane gas flame lit, cigarettes lit, tablet and radiation heat ignites. According to the evaluation criteria, it can be divided into flame continuation and flame retardation time, average carbon length, flame spread time within the prescribed combustion distance, flame spread rate, damage area and flame connection times within the prescribed time.
Liside always dedicated to the development,manufacturing and applications of high performance flame retardants.
