Melt flow rate testing machine: a specialized equipment for measuring the melt flow rate of thermoplastic under certain conditions, and can indirectly determine the molecular weight of high polymers. The melt flow rate (melt index) of thermoplastic refers to the mass or volume of molten plastic passing through a standard specimen outlet every 10 minutes at a certain temperature and load, expressed as MFR (MI) or MVR value, which can distinguish the viscous flow characteristics of thermoplastic in the molten state. The quality assurance of raw materials and products for thermoplastic and synthetic fibers is of great significance.
Mainly used in factories, product quality inspection institutes, research institutions and other units for the production, inspection, development, research and other fields of plastics. This machine has high temperature control accuracy, key parts undergo nitriding treatment, high strength and hardness, and small deformation, which provides good conditions for accurately measuring flow rate.
