PP Filled Masterbatch is a type of functional masterbatch developed to solve problems of traditional PP products such as single mechanical properties, high cost and insufficient adaptability to specific scenarios. It focuses on accurately optimizing PP product performance through multi-filling systems according to different application needs while achieving cost control, providing customized solutions for PP products in home appliances, automotive, construction materials and packaging fields. This type of masterbatch usually selects carrier resins with excellent compatibility with PP substrates; for general processing scenarios, homopolymer PP or copolymer PP with melt flow rate (MFR) 12-28g/10min is often used as carrier; for high-fluidity processing, modified PP carrier with MFR 30-45g/10min is selected to ensure efficient integration with various PP substrates, avoiding product delamination, surface defects or performance fluctuations caused by poor compatibility between carrier and substrate.
In terms of application scenarios, PP Filled Masterbatch covers differentiated needs in multiple fields: in the automotive field, glass fiber filled masterbatch is used to produce PP door anti-collision beams and instrument panel skeletons, improving structural strength and temperature resistance to meet the needs of high temperature and external impact in the car; in the home appliance field, calcium carbonate or talc filled masterbatch is used for refrigerator drawers and washing machine bases, enhancing rigidity and dimensional stability to ensure accurate assembly and durability of components; in the construction material field, hollow glass microsphere filled masterbatch is used for PP sound insulation boards and lightweight profiles, improving sound insulation and heat insulation effects on the basis of lightweight.
