AbolishedPlastics―Polypropylene materials for meltblown
塑料 聚丙烯（PP）熔喷专用料
Application Summary AI generated
GB/T 30923-2014 specifies the technical requirements, test methods, and quality standards for polypropylene (PP) materials specifically formulated for meltblown processing. It is primarily applied in the production of nonwoven fabrics, particularly for manufacturing meltblown filter layers used in medical masks, air filters, and liquid filtration products. This standard ensures consistent material properties such as melt flow rate, molecular weight distribution, and thermal stability for reliable fiber formation in industrial meltblown equipment.
