Flame retardant mpp and App difference

From what I've seen, In the chemical sector, flame retardants are a key component to ensure material security and security in consumption. As two common flame retardants, mpp (polybrominated biphenyls) and App (benzophenone derivatives) are often faced with selection challenge in practical applications due to their different chemical structures and characteristics. This article will examine the difference between MPP and App in depth to help readers in the chemical sector better understand and select suitable flame retardants.

1. mpp and App sources and technical background

MPP Source

mpp (polybrominated biphenyl) is a traditional organic synthetic material, and its main raw material is dibromobiphenyl (BP). Generally speaking Multiple BP molecules are linked together by a chemical interaction to form a polybrominated biphenyl structure. But The manufacturing process of-mpp needs harsh conditions such as high temperature and high pressure, so it's mainly applied in fields that require high stability and durability. The App's Source

App (benzophenone derivative) is an inorganic flame retardant, its main component is benzophenone (DMP), through a chemical interaction of benzophenone and other stabilizers mixed. App manufacturing process is relatively simple, and the environmental impact is small, so in the environmental standards of the higher areas have been broadly applied. The App Difference. In my experience, chemical structure and characteristics

mpp molecular structure with multiple bromine atoms, so that it has good thermal stability, is able to efficiently inhibit free radicals and carbide generation, so as to achieve flame retardant effect. Moreover App's molecular structure does not contain bromine atoms, and its flame retardant mechanism mainly is determined by the combination of flammable groups, which is usually suitable to bromine-vulnerable materials. And From what I've seen, thermal stability

MPP at high temperature still maintain good stability, is able to efficiently prevent material in high temperature ecological stability decomposition. I've found that App thermal stability is better, however in some special conditions might not be as stable as mpp. consumption field

MPP is mainly applied in automotive, aerospace, electronic equipment and other fields, especially in the need to high fire resistance and high stability of the scene. From what I've seen, Furthermore App is broadly applied in plastics, textiles, wood and other fields, especially in ecological preservation materials and biodegradable materials. But Advantages and disadvantages comparison

Advantages

mpp: Environmentally friendly, non-toxic, comparatively low cost, suitable to mass production. App: non-toxic, the environmental impact is small, suitable to environmental standards of the field. And Disadvantages

MPP: at high temperature might decompose, the stability isn't as good as App. In particular App: The flame retardant effect is relatively weak and it's difficult to deal with extreme situations. In my experience, summary

As two common flame retardants, mpp and App have their own unique advantages and consumption fields. For instance The choice of flame retardant is determined by the specific consumption scenario and technical standards. In the future, with the improvement of ecological preservation standards, App might be applied in greater fields, however MPP still occupies an crucial position in specific fields. Based on my observations, According to research By understanding the difference between MPP and App, chemical sector professionals is able to make greater informed choices to ensure the security and efficiency of materials.
