This article presents a comprehensive review and comparative analysis of two key methods for modifying polypropylene composites—radiation and peroxide crosslinking. Polypropylene, with its high physicochemical properties, is widely used in construction, automotive, electrical engineering, and other industries. However, the need to improve its thermal resistance, strength, and durability necessitates additional modification of its macromolecular structure. The crosslinking methods under consideration enable the formation of a three-dimensional network structure, which significantly enhances the performance characteristics of the material. The article analyzes the mechanisms of network structure formation, the influence of process parameters on crosslinking efficiency, and provides a comparison of the resulting composites in terms of various physical, mechanical, and thermal properties. The relevance of choosing a method based on the specific end-use application is substantiated, emphasizing the potential for further research in the field of polymer engineering. Potential application areas for the modified composites are discussed, including their use in high-tech industries where enhanced strength and resistance to environmental factors are required. Additionally, the ecological and economic aspects of implementing crosslinked polypropylene in industry are addressed. Particular attention is given to issues of technology scale-up and integration of developed solutions into existing manufacturing processes. At the same time, challenges related to the control of the degree of crosslinking and the need for standardization of the resulting materials are analyzed. In conclusion, the importance of selecting the optimal crosslinking method to achieve the desired properties of polypropylene composites is highlighted, as it can significantly influence their market competitiveness. Examples of successful industrial implementation of these technologies are provided.
