Plastic Melt Flow Rate Index Tester MFI Testing Device

Product Description

Plastic Melt Flow Rate Index Tester MFI Testing Device

Model:DH-MI-BP
 

The melt flow rate meter is a special instrument for determining the melt flow rate of a thermoplastic under certain conditions. It refers to a molten material extruded from a die of a specified length and diameter under a certain temperature and load. Mass flow rate MFR or melt volume flow rate MVR, which can distinguish the viscous flow characteristics of thermoplastics in molten state; it is of great significance for the quality assurance of thermoplastics and chemical fiber raw materials, products, etc., especially in quality. Inspection and warehousing testing.

This series of melt indexer is specially designed for fast and accurate measurement. It has the characteristics of firm structure, easy operation, stable and reliable performance. It uses high-precision PID thermostat technology, high temperature control precision, nitriding of key parts, high strength and hardness. The thermal expansion deformation is small. DH-MI-BP,DH-MI-VP is a regular model, manual loading weight with automatic cutting function; DH-EI-BP,DH-EI-VP is the model with an electric loading weight with automatic cutting function.which means the weights is placed on the weight bracket in advance for electric loading and unloading, reducing manual operation. The DH-AI-VP is a fully automatic model with automatic loading weight and automatic cutting function, which automatically loads and unloads the corresponding weight according to the set mode.to further improve measurement efficiency.

Usage:

It is used to determine the melt mass rate flow rate MFR value or melt volume rate flow rate MVR value of various plastics and resin polymers in the viscous flow state. It is suitable for polycarbonate, polyarylsulfone,fluoroplastics and nylon which has higher melting temperature.It is also suitable for polyethylene (PE), polystyrene (PS), polypropylene (PP), ABS resin, polyoxymethylene (POM), and polycarbonate (PC) resins.which has lower melting temperatures 

Remarks: Testing fluorine material is optional

Application industry:
