SN-NA Touch Screen Melt Flow Indexer_Melt Flow Indexer_Guangzhou Sono Scientific Instrument Co., Ltd.
Function and Use
The melt index tester of Guangzhou Shounuo Scientific Instrument Co., Ltd. is used to measure the mass flow rate (MFR; unit: g/10min) of thermoplastic melts. It is suitable for the determination of the melt index of various polymer plastic raw materials such as polyethylene, polystyrene, polypropylene, ABS resin, polyoxymethylene resin, polycarbonate, nylon, fluoroplastics, etc. at high temperatures. It is widely used in plastic raw material production, plastic products, petrochemical and other industries as well as relevant colleges and universities, scientific research departments and commodity inspection departments.
Test Principle
This product uses a high-temperature heating furnace to make the object to be tested reach a molten state under specified temperature conditions. The object to be tested in this molten state is extruded through a small hole of a certain diameter under the load gravity of the specified weight. In the plastic production of industrial enterprises and the research of scientific research units, "melt (mass) flow rate" is often used to indicate the physical properties of polymer materials in the molten state, such as fluidity and viscosity. The so-called melt index refers to the average weight of each section of the extrudate sample converted to the extrusion volume of 10 minutes.
