Modified PP Granules For Melt-blown Nonwovens

Question & Answer

Question: How to circumvent the problem of poor material flow?

Answer: The MFI of the Modified PP Granules For Melt-blown Nonwovens is a very critical indicator. A good melt finger and stable quality does not only depend on the material, but also the equipment is very important.

• The accuracy of the measuring equipment should be high

• Suitable choice of replenishment material level to avoid feeding fluctuations caused by impact when replenishing material

• Liquid feeding needs to achieve continuous and stable output in a short period of time

Without high precision feeding equipment, the melt finger fluctuates a lot. The difference of melt finger ±200 is a big headache for cloth manufacturers. Our Modified PP Granules For Melt-blown Nonwovens has a stable melt finger; after our customer used this meltblown material to make meltblown cloth, the test salt particulate filtration efficiency (PFE) reached more than 95%.
