The function of dispersant is to evenly disperse the color masterbatch and no longer agglomerate. The dispersant should have good compatibility with the resin and have certain thermal stability; The melting point should be lower than resin to facilitate melting and dispersion; It also needs to have a good affinity with pigments.

(1) Generally speaking, the dispersants used in color masterbatch include white oil, zinc stearate, polyethylene wax, stearic acid, paraffin, EBS, etc. However, before selecting, it is necessary to clarify the condition of the color masterbatch you are using. Different types require different dispersants.

(2) If used as a filling agent, titanium acid or aluminum ester may be better. In terms of comprehensive effect comparison, composite dispersants can be considered; Taking into account price and cost, a certain proportion of single paraffin wax can be used, and polyethylene single cracking wax can be used as a dispersant, which has a better effect.

It should be said that there are still many forms of single dispersants available for us to choose from when using color masterbatch sheets. This way, we can choose and use more suitable dispersants according to different usage environments, in order to better achieve our effects.
