1.What materials are black masterbatch made of? 

Black masterbatch materials are: a. Carbon black; B. Carbon black carrier; C. Carbon black wetting agent; D. carbon black dispersant; E. Other processing AIDS. 

2.Why does carbon black need a wetting agent?

The proportion of carbon black is about 2g/cm. Because of the small size of carbon black, the performance density is very small, appears fluffy and seems to be very light.To process smoothly, the carbon black must first be wetted. The choice of wetting agent is very important. In order to reduce costs, a large number of enterprises using white oil or paraffin products, will seriously affect the strength of the processed products.

3.Does black masterbatch also need processing aid?

Yes, of course. A smooth process requires proper selection of antioxidants, internal lubricants, external lubricants, modifiers and antistatic agents.

4.Do processing methods affect the properties of masterbatch?

Yes. It is obvious that the internal refining method can improve the carrying capacity of the carrier, and the carbon black can enter the carrier more evenly. It can not be replaced by other two methods to give full play to the mechanical kneading advantage of internal mixer and break the agglomerated particles, so that the agglomerated particle size of carbon black particles is greatly reduced, and the particle size and distribution of carbon black in master batch are uniform.

5.How to distinguish rubber with wear-resistant carbon black made of black masterbatch? 

According to the packaging, it is only half a bag, very dark and heavy, and the price is very low. After joining the equipment, the current increases immediately, the torque increases, the plastic processing temperature is improved, the fluidity is still poor, the product coloring is difficult.
