The melt flow index (MFI) or melt flow rate (MFR) is a measurement used to assess the flowability or melt viscosity of a polymer. It provides an indication of how easily a polymer can be …

Glycolysis of post-consumer polyethylene terephthalate (PET) waste is a promising chemical recycling technique, back to the monomer, bis (2-hydroxyethyl) terephthalate (BHET). This …

The OM analysis revealed the coexistence of at least three phases - one rich in PET (matrix), the other rich in PC (dispersed droplet) and an interfacial region between them, made of PET/PC ...

MFI is expressed in grams of polymer per 10 minutes of duration of the test. Synonyms of Melt Flow Index are Melt Flow Rate and Melt Index. More commonly used are their abbreviations: …

Injection moulding applications require high MFI values, whereas extrusion processes demand much lower values. Fig. 3 therefore shows wide spreads for the MFI parameter of the virgin …

The molecular weight of polyethylene terephthalate (PET) is usually described in terms of intrinsic viscosity. This is the IV value in dl/g. The longer the polymer chains, the higher this …

Understand the importance of the Melt Flow Index (MFI) in polymer processing. Learn how MFI helps determine polymer flowability, influencing material selection for processes like injection …

ISO 1133-1 标准确立了测定热塑性塑料的熔体质量流动速率 (MFR)和熔体体积流动速率 (MVR)的通用试验方法。 ISO 1133第2部分 (ISO 1133-2)描述了适用于对时间或温度相关历史和/或湿 …

塑膠流動性指數 (melt flow index)，簡稱MI或是MFI，是衡量塑膠升溫到加工溫度時，其流動性的重要依據參數。 本文根據ASTM D1238的規範，概述其測試方式與目的。

熔融指数（Melt Flow Index，MI or MFI），Melt Flow Rate（MFR）， 全称熔液流动指数， 或熔体流动指数，是指一种表示塑胶材料加工时的流动性能的数值。
