(China)YYP-400BT Melt Flow Indexer
Short Description:
Melt flow Indexer (MFI) refers to the quality or melt volume of the melt through the standard die every 10 minutes at a certain temperature and load, expressed by MFR (MI) or MVR value, which can distinguish the viscous flow characteristics of thermoplastics in the molten state. It is suitable for engineering plastics such as polycarbonate, nylon, fluoroplastic and polyarylsulfone with high melting temperature, and also for plastics with low melting temperature such as polyethylene, polystyrene, polyacrylic, ABS resin and polyformaldehyde resin. Widely used in plastic raw materials, plastic production, plastic products, petrochemical and other industries and related colleges and universities, scientific research units, commodity inspection departments.
