Plastic Melt Flow Index Tester

The Plastic Melt Flow Index Tester is a specialized device for determining the melt flow rate of thermoplastic plastics under specified conditions, and it can indirectly measure the molecular weight of polymers. The melt flow rate (MFR/MI) or melt volume flow rate (MVR) of thermoplastic plastics refers to the mass or volume of melt passing through a standardized die per 10 minutes under a specific temperature and load. This parameter distinguishes the viscous flow characteristics of thermoplastics in the molten state.

The tester is suitable for engineering plastics with high melting temperatures, such as polycarbonate (PC), polysulfone, fluoroplastics, and nylon, as well as plastics with lower melting temperatures, including polyethylene (PE), polystyrene (PS), polypropylene (PP), ABS resin, polyoxymethylene (POM), and polycarbonate (PC) resin. It plays a critical role in ensuring the quality of raw materials and products for thermoplastics and chemical fibers.
