The results show that medium-density PE (MDPE) presents the strongest compatibility with asphalt binder, followed by high-density PE (HDPE) and low-density PE (LDPE), respectively.

你必須要管控每一個環節的mfi，比如說射出廠的塑膠粒入料的mfi檢驗，以及射出後的mfi檢驗來驗證，如果可以要求塑膠粒廠商提供出貨的mfi值會更好，這樣子的經過射出後的30%或40%降解才有意義，至於30%或40%要看你們的產品來決定，要雙向要求塑膠射出廠及塑膠 ...

Feb 24, 2024 · Melt Flow Index (MFI) is an important parameter for measuring the processability of thermoplastics and is often used to characterize the melt viscosity or fluidity of a polymer. The higher the MFI, the better the material flows and the better it fills the mold.MFI is the mass of polymer melt flowing out per unit of time at a specific load and ...

MFIMFI – Melt Flow Index (MI) 概念解释全称熔体流动指数，又称熔融指数，表示塑胶材料加工时的流动数值，MFI是塑胶材料的机械性能重要指标之一，检验塑胶原料特性MFI，是指检测其的加工流动性特性，它是美国材…

What is melt flow index? What is the relationship between MFI and molecular weight? What is the influence of polymer MFI on their processing? How to modify the melt flow index of polymers? What is the effect of melt flow index of the filled polymers/composites? What are the standards for MFI measurements?

The Melt Flow Index (MFI) is a measure of the ease of flow of the melt of a thermoplastic polymer. It is defined as the mass of polymer, in grams, flowing in ten minutes through a capillary of a specific diameter and length by a pressure applied via prescribed alternative gravimetric weights for alternative prescribed temperatures.

塑料的“熔融指数”（MI），也称为“熔体流动指数”（MFI）或“熔体流动速率”（MFR），测量在设定的重量和温度条件下，10 分钟内有多少熔融塑料流过特定直径的管道。 熔融指数测试是评估热塑性材料流动性能的重要方法，提供熔融指数和熔融流动指数等基本指标，对于确保塑料制品的质量和加工性至关重要。 MI 值越高，塑料流动越容易，MI 值越低，塑料流动越困难。 熔体流动速率值是材料在压力下流动能力的关键指标，与分子量和粘度有关，对于为各种加工方法选择适当等 …

Nov 28, 2024 · The “Melt Flow Index” (MFI) of plastic refers to the weight (in grams) of molten plastic that flows through a standardized tube with a specific diameter under a defined load (in kilograms) and temperature (in °C) within a set period of time (typically 10 minutes).

MFI 是用于评估聚丙烯 (PP) 或聚乙烯 (PE) 的流动性或熔体粘度的测量方法。 聚烯烃的加工性能和应用与 MFI 相关。 例如，为了生产薄壁的杯子或桶，可以采用注射成型； 该技术需要相应流动性的聚合物，以便能够以良好的速度完全填充模具，从而最大限度地提高产量。 熔体流动指数与PP/PE的分子量直接相关。 长聚合物链（高分子量）导致高粘度，因此 MFI 低。 MFI 是用于评估聚丙烯 (PP) 或聚乙烯 (PE) 的流动性或熔体粘度的测量方法。
