Thermal stability refers to a material's ability to maintain its properties over a wide range of temperatures without undergoing degradation or significant changes in structure.

  • The hydrogen bonding network formed between Melamine hydrobromide and Polypropylene molecules provides additional stability to the polymer matrix, preventing the formation of defects and cracks at elevated temperatures.

  • The decomposition products of Melamine hydrobromide, such as nitrogen gas and water vapor, can act as a protective layer on the surface of PP, preventing heat from penetrating into the material and causing degradation.

  • Melamine hydrobromide's ability to form a protective char layer when exposed to heat helps to shield the PP matrix from thermal degradation, thereby extending its service life.

Experimental studies have shown that MHB-PP composites exhibit higher thermal stability compared to neat PP, with improved resistance to thermal oxidation and reduced weight loss at elevated temperatures.

This enhanced thermal stability is particularly beneficial in applications where PP is exposed to high temperatures or harsh environmental conditions, such as in automotive parts, electronics, and industrial components.

By improving thermal stability, Melamine hydrobromide not only enhances the performance of PP but also contributes to its durability and longevity.
