Melt-Blown PP Granule

# We sell plastic raw material # Melt-Blown PP Granule

In theory, all thermoplastic (high temperature melt, low temperature cure) polymer slicing raw materials can be used in the meltblown process. Polypropylene (which we called Melt-Blown PP Granule) is one of the most used raw materials for the meltblown process.

The type of polymer determines its melting point and rheological properties. For each polymer raw material, there is a corresponding meltblowing process, such as in heating temperature, screw L/D ratio, screw form, raw material drying process, etc. There are certain differences.

One of the characteristics of meltblown nonwovens is that the fiber fineness is small, usually less than 10 μm, and most of the fiber fineness is 1 to 4 μm.

From the meltblown die spout hole to the receiving device of the entire spinning line of the various forces can not be maintained in balance (high temperature and high speed airflow of the tensile force fluctuations, cooling air speed and temperature, etc.), so that the meltblown fiber fineness of different sizes.

The uniformity of fiber diameter in the spunbond nonwoven fiber network is significantly better than that of meltblown fibers, because the spinning process is steady-state in the spinning process conditions, and the changes in drafting and cooling conditions fluctuate less.
