Masterbatch is composed of carrier resin, filler and various additives. The limit of additives or filler content in masterbatch is several times to more than ten times higher than that in actual plastic products. Masterbatch is the most representative masterbatch in plastic masterbatch. Polyethylene wax is widely used in masterbatch processing. The purpose of adding pe wax is not only to improve the processing performance of masterbatch system, but also to promote the dispersion of pigments in masterbatch. Pigment dispersion is very important for masterbatch. The quality of masterbatch mainly depends on the dispersion of pigment.
Qingdao Sainuo pe wax SN118 has high molecular weight, high viscosity, Both lubrication and dispersion. the dispersion performance is equivalent to BASF A wax and Honeywell AC6A. Widely used in . High concentration difficult to disperse masterbatch, PVC soft rubber granulation, Metallurgical injection, etc.
The masterbatch with good pigment dispersion has high coloring power, good coloring quality and low coloring cost. The main additives used in masterbatch are dispersant and surface treatment agent. The function of dispersant is to improve the processing fluidity of masterbatch, which is conducive to more uniform dispersion of masterbatch in matrix resin. Common dispersants include white oil (Liquid Paraffin), paraffin, dioctyl phthalate (BOP), low molecular weight polyethylene (polyethylene wax) and stearic acid. The main properties of dispersant can be selected and used according to the performance characteristics of filler and carrier resin. Polyethylene wax can improve the dispersion level of pigment to a certain extent. It is the most commonly used dispersant in the production of masterbatch.
When the masterbatch system containing polyethylene wax is processed, the pe wax melts before the carrier resin and is coated on the pigment surface. Due to its low viscosity and good compatibility with pigments, polyethylene wax is easy to wet pigments, penetrate into the internal pores of pigment aggregates, weaken cohesion, make pigment aggregates easier to open under external shear, and new particles can also be quickly wetted and protected. In addition, polyethylene wax can reduce the viscosity and improve the fluidity of the system. It can effectively solve the precipitation phenomenon of filling masterbatch products; It can effectively reduce the smoke generated in the production environment and reduce material consumption. Especially, while increasing the output, it can effectively reduce the torque and head pressure of the twin-screw extrusion granulation unit and reduce the host current; When downstream customers are applied in plastic products, the product dispersion is uniform, and the product appearance is also significantly improved, which can greatly improve the surface finish and toughness of the products.
