                      How Tetrabromobisphenol A Flame Retardant and Fireproof

                        來源:www.sata-uk.com
                      Tetrabromobisphenol A is widely used in industrial production. What is the principle for people who first contact tetrabromobisphenol A? Maybe it is still strange, and more or less there will be various concerns about whether it is really effective and whether it will affect the characteristics of the product itself.
                      After tetrabromobisphenol A is added to the object, the flammable molecules in the vicinity will be taken away, and the fireproof and thermal insulation body will be added. When the value is less than a certain critical value, the original molecular stability will be destroyed, resulting in molecular breakage. Therefore, the fireproof, thermal insulation and flame retardant properties will be generated.
                      Here, we would like to remind everyone that we should correctly choose the type of flame retardant. When used at low, medium and high temperatures, it will not cause accidents. It will be fast flame retardant, and it will maintain performance for a long time. It will not produce molecules that affect dispersion again in the next process. It is safe, non-toxic, and in line with environmental requirements.
