In the fields of modern flame retardant materials, ceramic precursors, and catalytic carriers, the particle size uniformity and morphology regularity of nanoscale aluminum hydroxide (Al(OH)₃, especially Gibbsite phase) directly determine its performance limit.

The environmental stability of flame retardants directly determines the service life and safety of end products in application fields that require long-term reliability, such as electronics and electrical engineering plastics.

In the design and development of flame-retardant polypropylene (PP) materials, a frequently overlooked yet crucial scientific question is: How does the molecular chain structure of PP itself influence its flame retardancy? From the perspectives of polymer chemistry and combustion science, this study systematically analyzes the fundamental differences between homopolymer polypropylene (Homo-PP) and copolymer polypropylene (Co-PP) in terms of thermal degradation behavior, char formation, and interactions with flame retardants, providing a theoretical basis for the selection and formulation design of high-performance flame-retardant PP materials.

In the practice of halogen-free flame retardancy for polypropylene (PP), the "addition amount" is the core parameter determining the final material performance and cost-effectiveness. However, there is no universal "optimal addition amount," as its value results from a complex balance among flame retardant technology routes, target performance levels, polymer matrix characteristics, and cost constraints.

Testing and evaluating the flame retardant rating of polypropylene (PP) materials is not simply a matter of "ignition observation", but a systematic quantitative analysis based on rigorous combustion science and following global standardized procedures.

In the halogen-free flame retardant process of polypropylene (PP), a common and thorny contradiction is that the successful achievement of flame retardant grades (such as UL94 V-0) often accompanies a significant decrease in material impact toughness, manifested as increased brittleness and easy cracking of the product.
