Color masterbatch is a great plastic colorant, and most of our daily items are made of plastic in various colors. The stability of product color is also an important factor for the aesthetics and high added value of plastic products. Pe wax has become the first choice for color masterbatches due to its excellent performance. This article follows the footsteps of Qingdao Sainuo editor to learn more.

Polyethylene wax is mainly used in polyolefin masterbatch, including polyethylene masterbatch, polypropylene masterbatch, and EVA masterbatch. Polyethylene wax is used as a pigment wetting and dispersing agent in polyolefin masterbatches. Mainly reflected in the wetting, dispersion, mixing, and stability of pigments after dispersion.
The rich colors and good glossiness of plastic products can improve their aesthetics and added value, so it is necessary for the color masterbatch to have high coloring power. Polyethylene wax has excellent lubrication and dispersion capabilities, and has good compatibility with resins such as polyethylene, polyvinyl chloride, and polypropylene. It can increase the extrusion performance of color masterbatch, improve production efficiency, and also increase the glossiness and processing performance of the product.

Polyethylene wax is used in color masterbatches. Due to the large amount of pigments or fillers used and the small particle sizes of these pigments and fillers, they are easily agglomerated in the 0.01 to 1.0 micron range. By adding homopolymer polyethylene wax, the polyethylene wax melts within a certain temperature range to wet the surface of pigments or fillers.

Polyethylene wax has good compatibility with pigments, is easy to wet pigments, and can penetrate into the internal pores of pigment aggregates, weaken cohesion, and make pigment aggregates more easily broken under external shear force. Newly generated particles can also be quickly wetted and protected. In addition, polyethylene wax can also reduce the viscosity of the system and improve flowability. Therefore, adding polyethylene wax during the production of color masterbatch can improve production efficiency and yield, and stabilize the dispersion effect.
