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 problem still exists, to some extent, restricted the development of polypropylene its application in many fields. In order to overcome performance deficiencies, today, as we introduce Chun Chi PP masterbatch production aid options.

1 color choice

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 Select carrier

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 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.

Use 4 affinity agent

In the recipe, adding the affinity agent is a major component of the salient features of this article. Its role is to improve the pigment molecule chemistry and PP macromolecular chains, thereby reducing the pigment "blooming" and transport phenomena.
