PP material for meltblown
PP material for meltblown is used for the production of the filtration layer of the facial mask. It is with very high MFI PP.
Meltblown is a polymer based technology where high-velocity air attenuates extruded fibers that are much finer than spunbond. These fine fibers provide exceptionally high surface areas for multiple applications, especially filtration.
The main materials are PP and DCP, where the DCP reduces down the molecular weight, which results in the lower processing temperature (20-30℃) and the increase of the MFI of the PP resin.
XINDA twin screw extruder for Meltblown PP has the following advantages:
1, Automatic dosing system: loss-in-weight feeders are used for the dosing of PP and DCP, which guaranteed the high accuracy for the stable MFI of meltblown PP.
2, Special die head design: special designed channels enables high-flow melts uniformly runs in the die head with same dwell time.
3, high torque gearbox: high torque gearbox guarantees a relatively longer dwell time for the PP and DCP, which reduce down the fluctuation of MFI.
