Melt Flow Rate Test System (Melt Index Meter)

Melt flow rate test system (also known as melt index instrument) is a special instrument for measuring the melt flow rate of thermoplastic under certain conditions. The melt flow rate (melt index) of thermoplastics refers to the mass or melt volume of the melt passing through the capillary tube of standard die every 10 minutes under a certain temperature and load. It is expressed by MFR (MI) or MVR value. It can distinguish the viscous flow characteristics of thermoplastics in the molten state. It is of great significance to the quality assurance of thermoplastic and chemical fiber raw materials and products. This machine has high control temperature precision, nitriding treatment of key parts, high strength and hardness, small deformation, which provides good conditions for accurate measurement of flow rate.
