What Dispersant Is Used For TPU Masterbatch?

What dispersant is used for TPU masterbatch? The function of the dispersant is to make the masterbatch evenly dispersed and no longer agglomerated. When selecting a dispersant, the dispersant should have good compatibility with the resin and a certain degree of thermal stability; the melting point should be lower than that of the resin so that it can be melted and dispersed completely; and it should have good affinity with the pigment.

(1) Generally speaking, the dispersants used in masterbatch are: white oil, zinc stearate, polyethylene wax, stearic acid, paraffin, EBS, etc., but before choosing, you must first clarify the situation of using the masterbatch. Different types require different dispersants.

(2) If used as a filler, it is better to use titanate or aluminate; in terms of comprehensive effect comparison, you can consider a composite dispersant; if you consider price and cost, you can add a certain proportion of paraffin, and use polyethylene cracking wax as the dispersant, which will have better effect and higher comprehensive cost performance.

It should be said that in the process of using masterbatch, there are still many forms of dispersants for us to choose from, so that we can choose more suitable dispersants according to different usage environments to better achieve the desired effect.
