Melt Flow Index

Melt flow index refers to the mass in grams of thermoplastic material that passes through a standard die within 10 minutes under specified temperature and pressure conditions. The principle is based on the flow properties of plastic melts and is used to evaluate the processing fluidity of materials. Its role lies in guiding the setting of plastic molding process parameters, and its applications include plastic production, quality control, and material selection in research and development.
Selection
The selection of melt flow index should consider material type, processing technology, and product requirements. Match the test temperature and pressure to the actual processing conditions, and select the appropriate die according to standards such as ASTM D1238. Refer to supplier data sheets to ensure that the instrument's accuracy and repeatability meet industry specifications.
