ActivePlastics - Polypropylene(PP) and propylene copolymer thermoplastics - Determination of isotactic index
塑料 聚丙烯(PP)和丙烯共聚物热塑性塑料等规指数的测定
Application Summary AI generated
This standard specifies a method for determining the isotactic index of polypropylene (PP) and propylene copolymer thermoplastics by measuring the fraction insoluble in boiling n-heptane. It is applied in the plastics industry for quality control and material characterization, particularly for assessing the stereoregularity and crystallinity of PP resins used in injection molding, film extrusion, and fiber production. The test ensures consistent mechanical and thermal properties in end products like packaging, automotive parts, and textiles.
