As we all know the plastic black above the market now is the mother of good and evil people mixed up, a variety of different products the price of this piece is not the same. So since there are so many different varieties, and will lead to the choose and buy when we will be not very well selected, but small make up today to tell you how to choose a good plastic black female?

When we in the choice must pay attention to several issues, the first is stronger; The second factor in determining the quality of black masterbatch is covering power, for waste or recycled polymer masterbatch, this factor is particularly important, in these cases, the role of the black waste is to cover the other colors. Large particles of carbon black coloring ability is poorer, difficult to cover all of the other in the color of the lower, the results of the final product only get off color.

In the process of melting, correctly select high tinting strength the ability of carbon black to override the existing color is known as a covering force. The second is better liquidity; A third factor in determining the quality of black masterbatch is rheology and liquidity. If a masterbatch itself has good dispersion property, but it can't flow into to die casting material, the production effect is not ideal.

And the dispersion degree is higher; Black masterbatch is to use carbon black to produce. Carbon black is very difficult to handle and a mixture of dirty, it was full of dust, light and fluffy. Unless the large-scale processing measures, otherwise it will be dirty machines and workers, make work environment becomes dirty.

The last is compatibility is larger; Compatibility decisions plastic black mother of the fourth factors on the quality of the masterbatch. If the masterbatch is the use of chip or reworked material to produce, so it may contain contaminants or other molten polymer.
