Flame retardant mpp and App difference

In the chemical industry, flame retardants are a key component to ensure material safety and safety in use. As two common flame retardants, mpp (polybrominated biphenyls) and App (benzophenone derivatives) are often faced with selection challenge in practical applications because of their different chemical structures and properties. This article will analyze the difference between MPP and App in depth to help readers in the chemical industry better understand and select suitable flame retardants.

1. mpp and App sources and technical background

1. MPP Source

• mpp (polybrominated biphenyl) is a traditional organic synthetic material, and its main raw material is dibromobiphenyl (BP). Multiple BP molecules are linked together by a chemical reaction to form a polybrominated biphenyl structure. The production process of-mpp requires harsh conditions such as high temperature and high pressure, so it is mainly used in fields that require high stability and durability.

1. The App's Source

• App (benzophenone derivative) is an inorganic flame retardant, its main component is benzophenone (DMP), through a chemical reaction of benzophenone and other stabilizers mixed.
• App production process is relatively simple, and the environmental impact is small, so in the environmental requirements of the higher areas have been widely used.

The App Difference.

1. chemical structure and properties

• mpp molecular structure with multiple bromine atoms, so that it has good thermal stability, can effectively inhibit free radicals and carbide generation, so as to achieve flame retardant effect.
• App's molecular structure does not contain bromine atoms, and its flame retardant mechanism mainly depends on the combination of flammable groups, which is usually suitable for bromine-sensitive materials.

1. thermal stability

• MPP at high temperature still maintain good stability, can effectively prevent material in high temperature environment decomposition.
• App thermal stability is better, but in some special conditions may not be as stable as mpp.

1. Application field

• MPP is mainly used in automotive, aerospace, electronic equipment and other fields, especially in the need for high fire resistance and high stability of the scene.
• App is widely used in plastics, textiles, wood and other fields, especially in environmental protection materials and biodegradable materials.

Advantages and disadvantages comparison

1. Advantages

• mpp: Environmentally friendly, non-toxic, relatively low cost, suitable for mass production.
• App: harmless, the environmental impact is small, suitable for environmental requirements of the field.

1. Disadvantages

• MPP: at high temperature may decompose, the stability is not as good as App.
• App: The flame retardant effect is relatively weak and it is difficult to deal with extreme situations.

Conclusion

As two common flame retardants, mpp and App have their own unique advantages and application fields. The choice of flame retardant depends on the specific use scenario and technical requirements. In the future, with the improvement of environmental protection requirements, App may be applied in more fields, but MPP still occupies an important position in specific fields.

By understanding the difference between MPP and App, chemical industry professionals can make more informed choices to ensure the safety and efficiency of materials.
