Coverage is stronger
The first factor determining the quality of the dyeable polypropylene masterbatch is the coverage force, which is useful for colorants used in waste or recycled polymers

This is particularly important in the case of particles, where the effect of black is to cover the rest of the waste material

color. Large particles of carbon black coloring ability is poor, not easy to cover all other colors in the lower layer, the results of the final product

Only get the color deviation. In the melting process, the right to choose the first high-color ability to cover the current carbon black

The ability to have color is the so-called covering power.

Liquidity is better
The second factor determining the quality of dyeable polypropylene masterbatch is rheology and fluidity. If a masterbatch itself has good

Good dispersion, but it can not flow into the material to be molded, the production effect is not ideal. one

In general, the base resin used to produce masterbatches has a high rheology. In order to save costs, some masterbatches

Grain producers use recycled materials, scrap, or recycled materials as resin carriers. The flow of the masterbatch thus produced

If the rheology is not good, mold workers in the cycle time and appearance of treatment encountered Ma

bother. It is noteworthy that, if the dispersion and rheology is not high, some end-users will increase the dilution ratio

To make up, but this approach will only increase the use of masterbatch cost. The masterbatch with the smallest dilution ratio may be used

To produce uniform, good dispersion of black.

Compatibility to be large
The third factor determining the quality of polypropylene masterbatch. If the masterbatch is the use of chips or recycled raw material

, It may contain contaminants or other non-meltable polymers. This can cause some unpredictable

Material, difficult to restrain the trouble, wasting time and raw materials of the final consumer. At this time, you can use the primer tree

Grease to produce high-quality masterbatch, Masterbatch in the melting process have a good compatibility. Quality masterbatch can be

Use LLDPE, LDPE, HDPE, PP, PS, SAN, PA and other materials to produce. If the project has been identified

Class and rigorous physical properties, then a special polymer masterbatch can be obtained. Several large international masterbatch

Grain producers, are conducting research to produce the so-called "universal" masterbatch. These masterbatches

Can be a wide range of raw materials and other capacity, with good rheology, can be applied flexibly.

Stability should be consistent
In today's international economy, the international customers of the masterbatch quality, stability and raw materials such as high performance requirements

Is absolutely necessary, and this is the fifth factor in determining the quality of the black masterbatch. Stability of a major performance on

Is a smooth ratio of carbon black. If the percentage of carbon black is fluctuating, the amount of masterbatch that needs to be melted is

Not the same, to produce the same color of the product is not possible. Some of the final producers reflect: the requirements of the thin

Release ratio is usually 5-8% difference, depending on the masterbatch manufacturers in the manufacture of the input of the number of materials. Apparently this is

unacceptable. Of course, other factors such as the flowability and dispersibility of the injected melt should be proportional to the quantity fed per batch

.

Brightness to be clear
The final factor determining the quality of the dyeable masterbatch is the shade of the color. There are various types of carbon black available on the market

For color masterbatch, but all kinds of color and price are also very different. Large particles of carbon black than small particles of carbon black

Has a lower degree of coloring and a different background. Large particle masterbatches are suitable for film production such as trash bags, but not

For those who focus on the production of beautiful products, such as TV signs or need to place the anti-ultraviolet such as agricultural thin

Membrane or external piping. For these products, only the use of high-priced small particles of carbon black. In addition, low transparency

Degree is also a feature of small particles of carbon black.
