How PP masterbatch production process, the selection aid it? Chun Chi Tengzhou tell you.

Polypropylene its light weight, corrosion resistance, high strength, hydrophobicity warm and good, low cost, rapid development in our country. Due to the lack of pro-staining groups on production of polypropylene of isotactic polypropylene materials macromolecular chains of molecular interactions are generally raw materials does not occur, the dye molecules difficult to spread between molecules, prone to bleeding and migration phenomenon, which affects the quality of products. Despite the large-scale production at home and abroad are in melt masterbatch coloring method, but most do not solve the affinity of the pigment molecules with the fiber molecules fundamentally dyed polypropylene difficult questions remain, to some extent, restricted the polypropylene fiber development and application in many fields. To overcome the above defect performance, here to tell you about PP masterbatch production aid options.

1, PP masterbatch pigment selection
       Since the polypropylene production technology under harsh conditions, pigment is required to have a heat resistance movement, small fineness, easy dispersion characteristics, can meet the above requirements and can be used polypropylene pigments are not many, most domestic manufacturers or self-pigment treatment or direct selection of pre-dispersed pigments. Swiss imports Yan Pageant series pigment dispersion was carried out after the feed production process to ensure that the pigment of superior performance, while the smaller particle size, so as to achieve good dispersion purposes.
2, PP masterbatch carrier selection
       Since polypropylene spinning speed, and the molecular weight distribution and ash and other indicators of the matrix resin, there are strict requirements, some domestic manufacturers used by the US company Philip K resin, DuPont EVA-565 and Samsung EVAE-141, etc. as the carrier, the effect is ideal.
Select 3, PP masterbatch dispersant
       Currently, most domestic manufacturers are using low molecular weight PE wax as a pigment dispersant. Its production by pyrolysis, low-temperature dispersion, impurities affect the quality of masterbatch, some manufacturers use low molecular weight polymeric wax BASF company, but more expensive. Some manufacturers use domestically produced low-molecular polypropylene wax as a dispersing agent, which is characterized by high PP wax softening point, with a certain amount shuttle group and by groups on the molecular chain of oxidized PE wax, pigments and resins compatible with the superior low-molecular PE wax.
4, the choice of PP masterbatch affinity agent
       In the recipe, adding the affinity agent components is a major outstanding characteristics. Its role is to improve the pigment molecule chemistry and PP macromolecular chains, thereby reducing the pigment "blooming" and transport phenomena.
