Modified PP Granules

# We sell plastic raw material # Modified PP Granules

In response to the poor impact resistance at low temperatures, poor weather resistance, poor surface decorative properties, and the gap between the functionality of polypropylene in electricity, magnetism, light, heat, and combustion, and the actual needs, Modified PP Granules has become the most active and fruitful area of plastic processing development.

PP Chemical Modification

Through copolymer modification, cross-linking modification, graft modification, nucleating agents, etc., polypropylene polymer components and macromolecular structure or crystal configuration changes to improve its mechanical properties, heat resistance, aging resistance and other properties to enhance its comprehensive performance and expand its application areas.

• Cross-linking modification

Cross-linking modification is the modification of linear or dendritic polymers by cross-linking into a net-like structure, which can improve the mechanical properties, heat resistance and morphological stability of PP (polypropylene) and shorten the molding cycle. The main methods of PP cross-linking modification are chemical cross-linking modification and radiation cross-linking modification, the main difference between them is the different cross-linking mechanisms and different active sources; chemical cross-linking modification is achieved by adding cross-linking additives to modify polypropylene, radiation cross-linking modification is mainly achieved by strong radiation or strong light, due to radiation cross-linking modification of PP thickness requirements make it difficult to popularize the method. At present, the silane graft cross-linking method is developing rapidly because of its ability to prepare materials with excellent performance. The PP produced by the silane graft cross-linking method has high strength, good heat resistance, high melt strength, chemical stability and good corrosion resistance.
