melt index

An interrelationship between the melt index and IV value is stored as a function on the instruments.

Polyethylene: The basics of the polymer and how density and melt index affect molded properties.

Engineers worked with programmers to ensure that polymer properties were introduced into the mathematical model for melt index and polymer density.

Researchers determine the melting index by multiplying how long melting took place by the area where the increased melting took place.

"This record melting index in those areas came as a bit of a surprise, showing us, once again, the extreme variability and complexity of these processes," said Tedesco.

The product made at the BSR can be tested for melt index, density, melt flow ratio (MFR), and productivity.

Synonyms of Melt Flow Index are Melt Flow Rate and Melt Index.

During a shearing process, such as extrusion, LLDPE remains more viscous and, therefore, harder to process than an LDPE of equivalent melt index.

He found that in high altitude areas over 1.2 miles above sea level, the melting index -- an indicator of where melting is occurring and for how long -- was significantly higher than average.

• In conjunction with material suppliers, several experiments were conducted on the production line with various compositions and melt index to identify a grade that could meet dimensional criteria at an acceptable mass flow rate.

According to Tedesco, melting in April and May of this year in high-altitude areas was very low, but in June melting jumped unexpectedly and led to the record melting index for the year.

The plastics engineer should choose a material with a melt index high enough that the molten polymer can be easily formed into the article intended, but low enough that the mechanical strength of the final article will be sufficient for its use.

Substrate & Material Compatibility Where the material the stake is moulded from is of a much higher melt index than the material being assembled to it, or where a thin thermo-plastic washer is being fitted, extreme caution must be observed.
