ActivePlastics - Determination of melting behaviour (melting temperature or melting range) of semi-crystalline polymers by capillary tube and polarizing-microscope methods
塑料 用毛细管法和偏光显微镜法测定部分结晶聚合物熔融行为（熔融温度或熔融范围）
Application Summary AI generated
This standard specifies two methods for determining the melting temperature or melting range of semi-crystalline plastics. It is applied in quality control and material characterization within the plastics manufacturing and processing industries, particularly for raw material inspection and product development. The capillary tube method is used for routine testing, while the polarizing-microscope method provides more precise observation of crystalline structure changes during melting.
