How it works to measure the flow properties of plastics and resins

Abstract: 熔体流动指数(MFI)测量是评估热塑性聚合物熔体流动性的重要方法。该测量通过在规定温度下,施加标准压力使聚合物熔体流经特定直径和长度的毛细管来进行。熔体流动速率仪帮助制造商监控和控制聚合物的质量,提高生产效率,并降低时间和成本。这些仪器不仅可以计算熔体流动指数(MFI)、熔体流动速率(MFR)和熔体体积速率(MVR),而且操作简便,提供可重复且可靠的结果,适合实验室自动化和高精度检测。

overview

According to Wikipedia, “Melt Flow Index is a measure of the ease with which a thermoplastic polymer melt flows. It is defined as the weight of the polymer, in grams method A specified pressure flows through a capillary of a specified diameter and length in place of a specified temperature.

If you are a manufacturer in the polymer industry looking to save time, energy and costs, a melt flow index measuring machine can be an asset to you.

A melt flow rate meter will help you monitor and control the quality of the polymers/plastics/thermoplastics you use. Melt flow rate meters help determine melt flow rate and melt flow volume rate. Plastics are the driving force behind polymer performance. The instrument can better control the quality control of raw materials and products.

The melt flow rate meter is very easy to operate and basically does not require highly qualified operators. It helps you automate your lab, saving time and money.
