How can you reduce Melt flow index of hdpe granules?
To reduce the melt flow index of HDPE granules, you can increase the molecular weight of the polymer by using a higher molecular weight grade of HDPE, incorporating chain extenders or cross-linking agents, or blending with a lower molecular weight polymer. These methods can help decrease the flowability of the material, resulting in a lower melt flow index.
What is relations of density MVI and MFI?
The Melt Flow Index (MFI) and Melt Volume Index (MVI) are both measures of a polymer's flow characteristics, but they differ in their testing conditions. MFI measures the mass of polymer that flows through a specific die over a set time under a defined load, while MVI measures the volume of polymer that flows under similar conditions. Generally, MVI can provide a more comprehensive understanding of a polymer's flow behavior at different shear rates. In practice, a higher MFI indicates a lower viscosity, while a higher MVI points to a greater flowability under the specified conditions.
What do you need to melt a solid in energy flow terms?
Melting is an exothermic process; we need heat for melting.
Why is treated rubber more desirable?
Treated rubber is made to not melt and flow when hot or be brittle when too cold.
What does melt condition mean?
Melt condition refers to the state of a substance transitioning from a solid to a liquid by heating it above its melting point. This process causes the substance's molecular structure to break down, allowing it to flow as a liquid.

Is polyproplene biodergradable?
No, polypropylene is not biodegradable but it is recyclable.
If the carr's index is 10how about the flow property?
if the carr's index for any type of powder is 10% than the flow property of the powder will be excellent.
What does a river usually flow down of?
Springs and glacial melt.
What causes air to be trapped in a mold?
melt flow patteren.
What is the melt flow rate of PP plastic?
The ease with which a thermoplastic polymer melt flows is gauged by the Melt Flow Index Tester (MFI). It is defined as the amount of polymer, measured in grammes, that flows in ten minutes through a capillary with a particular diameter and length under pressure from different gravimetric weights at different temperatures. The value of MFI is typically correlated by polymer processors with the grade of polymer that they must select for various processes, and most frequently, this value is not accompanied by the units because it is assumed to be g/10min.
Which finger has the most blood flow?
The index finger has the most blood flow among all the fingers.
What is the difference between viscosity and viscosity index?
Viscosity is resistance to flow of oil Viscosity Index is a scale to measure viscosity
What might cause solid rock in the Earth's interior to melt and begin to flow?
The mantle cause the mantle to flow.
Can a load be left in an autoclave overnight?
Can polyproplene produce oily residue through extreme heat
What is the relationship between viscosity and refractive index?
There is no direct relationship between viscosity and refractive index. Viscosity relates to the resistance of a fluid to flow, while refractive index is a measure of how much light bends as it passes through a substance. However, the refractive index of a substance may change with temperature, which can in turn affect its viscosity.
