Pigment vs Color Masterbatch Which Is Better

September 27, 2010 on 2:34 pm | In Tech | No Comments

The essential difference between pigment and color Masterbatch is: color masterbatch is pre-dispersed pigments in products. Color Masterbatch advantage is due in advance to do a good pre-dispersed, so very convenient to use, added directly, no need to do this step the dispersion. But the drawback is that overall costs masterbatch is relatively high.

The pigment has the advantage of relatively low overall costs, but requires the use of pigmentof the technical staff of the dispersion of pigment have good technical knowledge, or duplication of efforts, in addition to dust pollution. Personally, I think: If the factory funded, there are certain technical team can use the pigment completely, the costs can be reduced.

If the relatively small size of the factory, I still recommend buying more convenient color masterbatch, color matching technology are scattered, and let other people do, to be his last as long as the molding on it.

Chemical composition of plastic Color Masterbatch composition

1. Pigments or dyes

  Pigments are divided into organic pigments and inorganic pigments
  Commonly used organic pigments are: phthalocyanine red, phthalocyanine blue, phthalocyanine green, light red, red molecules, macromolecules yellow, Permanent Yellow, Violet, azo red. Inorganic pigments commonly used are: cadmium red, cadmium yellow, titanium dioxide, carbon black, iron oxide red, iron oxide yellow, etc.

2. Carrier

  Is the matrix of masterbatch. Selection and products exclusive resin masterbatch generally the same resin as carrier, the compatibility of the two best, but we must consider the carrier mobility.

3. Dispersant

  Make pigment evenly dispersed and no longer rally, the melting point of dispersing agent should be lower than the resin, the resin has good compatibility, and pigments have good affinity. The most commonly used dispersants are: low molecular weight polyethylene wax, stearic acid salt.

4. Additives

  Such as flame, brightening, anti-bacterial, anti-static, anti-oxidation and other species, unless the customer requests, generally do not contain the additive masterbatch.

The company has professional technical staff, according to the manufacturer’s requirements for different product colors timely and accurate preparation of the customers need a variety of high-quality mixed-dye, and a variety of high-end customers to meet the required colored plastic products, particularly prone to problems of the current PC, PA, PET, PVC, TPR, PP, PE and other plastic products is a unique coloring techniques.

They can also set up specifically for the customers private files, improve customer competitiveness of their products to meet customer demand for high-end color.
