The UL-94 and oxygen-index are used as the primary indicators of flammability. Thermo Gravimetric Analyzer, TGA, is utilized to analyze the decomposition temperature and measure the percentage of char residue. The linear regression graph obtained from the char residue and the oxygen index can be used to predict the flammability characteristics of the materials. The fundamental principle of flame retardant is the so-called “slightly-changed-in-a-big-way’s fires”. The fire could be easily extinguished when it is small. The legal restrictions and environmental protection concerns is the major driving force of the flame-retardant market. The halide and phosphoric free retardant is environmental-friendly and will become the mainstream of retardant technology development. The barrier for non-bromide-inorganic retardant is the reliability of its functionality and quality. Therefore, the development of standard testing methods, scale-up, processing, and the possible use of nano-scale additives are key factors for the successful promotion of inorganic flame retardant as a green product.
