PP Granules For Meltblown Fabric

PP granules for meltblown fabric are available in various grades that differ in their molecular weight, melt flow index (MFI), and other physical characteristics. The choice of a particular grade depends on the intended use of the fabric and the desired properties of the final product. For example, lower MFI granules are commonly used for producing finer and denser fabrics, while higher MFI granules are suitable for creating coarser and more porous fabrics.

Apart from the quality of the granules, the extrusion process itself plays a crucial role in determining the final properties of the meltblown fabric. Factors such as the extrusion temperature, pressure, melt viscosity, air pressure, and nozzle geometry must be carefully controlled to achieve the desired fiber size, shape, and distribution. Any deviation from the optimal process conditions can result in defects such as uneven thickness, poor fiber bonding, and reduced mechanical strength.

Our company has developed the most suitable raw material for healthcare and filtration by modifying PP granules to increase the melt flow rate and reduce the molecular weight distribution. Dawn modified PP has stable melt flow rate, low ash content, long spinning cycle and stable overall performance. We will customize the melt flow rate of polytene meltblown specialties in the range of 300 ~ 1900g/10min for you according to your product requirements.
