The pigment or dye masterbatch, carriers, dispersants, additives. Today, Ozawa and everyone of us for main and said masterbatch in the process of birth, the main choice of carrier and dispersant requirements! Welcome you to join a small partner Oh!

Choose carrier
Masterbatch carrier is a matrix, accounting for 30% to 50% masterbatch enable granular masterbatch, the carrier should have a good affinity with the pigment and compatibility with the coloring to consider when selecting a carrier Influence of the coloring system other properties and resin compatibility.

1. The carrier resin in the molecular structure is relatively reasonable, because of their properties of the carrier resin to make relatively good flow properties, in addition it has the mechanical ability to reach a certain level.

2. In order to improve the performance of the masterbatch, the carrier resin of the degree of branching can ensure softness and flow properties of the resin to maintain a good state.

3. In order to ensure the masterbatch in the application to have better gloss and chemical resistance, and therefore the carrier resin masterbatches can maintain a smaller degree of crystallinity.

Select dispersant
Dispersants can be encapsulated in the surface of the pigment particles, reducing the surface free energy of the pigment, the pigment dispersion into fine and stable particles are uniformly distributed in the melt, and agglomerate during processing does not occur. Typically require a dispersant and a pigment having good affinity with the carrier having good compatibility. From the economic and practical sense, it suggested the use of PP (polypropylene) wax as a dispersing agent, high softening point, narrow molecular weight distribution, no smell, can significantly improve the masterbatch coloring capacity, reduce color, reduce disruption silk spinning , drop wire phenomenon. The most commonly used dispersants are powdery or flake. Particles significantly larger than ordinary wax pigment particles, pigment particles to wrap uneven, suggested the use of micronized wax. Micronized wax and pigment particle size dimensions close, wax particles are filled between the pigment particles in the pigment particles can maintain a certain distance and provide wetting, can significantly improve the pigment dispersion.
