Retardant pp  masterbatch bred in the selection of the base resin

Retardant polypropylene masterbatch, which is characterized by flame-retardant effect, anti-aging, low spinning temperature, good thermal stability. PP flame retardant masterbatch is added after spinning, fiber achieves the technical specifications of spun silk white, and there is no smoke spinning, odorless, spinning components LOI period reaches over 72 h to 26 or more, join retardant polypropylene yarn quality masterbatch fully qualified.

Retardant polypropylene masterbatch production in the choice of the base resin requirements:

Retardant masterbatch polypropylene binder choice is extremely important, is directly related to the nature and impact of the product and the spinnability in the trial, the principle of screening binder PP are as follows:

1. Screening PP readily prepared narrow molecular weight distribution.
Because PP wide molecular weight distribution, the instructions on the PP resin molecular chain molecules, small molecules and the poor, the spinning process is easy breakage, wound groups to form large molecular weight gel particles, so that the spinning process occurs blocking filter, shorten the spinning cycle, so that the spinning process, the spinning temperature is difficult to control, difficult to draw, normal spinning is difficult, it must be readily prepared PP selected narrow molecular weight distribution.

2. Use easy drop negligent PP resin.
PP macromolecular chains easier because chain scission degradation, the molecular weight distribution of degraded conducive to further narrowed, it should be used in large molecular weight, the lower the melt flow rate of PP resin.

3. Use powder PP.
This facilitates PP powder and add a variety of additives and flame retardants were uniformly mixed, so that the production of fire-retardant PP Compound has good spinnability
