The role of polypropylene wax in ink

The role of polypropylene wax in ink


Polypropylene wax is a commonly used additive widely used in inks. It has multiple functions and provides important guarantees for the performance and quality of inks.

Polypropylene wax can act as a thickener. During the ink preparation process, adding an appropriate amount of pp wax can increase the viscosity of the ink and make it more dense. This helps ink to better adhere to the surface of printing materials during the printing process, improving printing quality and clarity. At the same time, thickeners can also prevent the layering and precipitation of ink during storage and transportation, maintaining the uniformity and stability of the ink.

PP wax can also provide the gloss and lubricity of ink. Adding polypropylene wax can form a thin film on the surface of the ink, increase the glossiness of the ink, and make the printed material more vibrant and beautiful. At the same time, this thin film can also reduce the friction between ink and printing materials, reduce printing energy consumption, and extend the service life of plates and machines.

Pp wax can also improve the wear resistance and durability of ink. Ink inevitably experiences wear and tear during the printing process, and adding an appropriate amount of pp wax can reduce the degree of ink wear and prolong the service life of printing plates and printing machinery. Meanwhile, pp wax can also increase the water resistance and weather resistance of ink, making printed materials more durable.

Polypropylene wax can also adjust the rheological properties of ink. The rheological properties of ink play an important role in the transfer performance and printing effect during the printing process. Adding an appropriate amount of pp wax can improve the rheological properties of ink, making it easier to transfer and apply, and improving printing speed and efficiency. Meanwhile, adjusting the rheological properties can also reduce ink splashing and volatilization, improving the safety and hygiene of the printing environment.

In addition, polypropylene wax also has anti-static and anti adhesive properties. During ink preparation and printing processes, the generation of static electricity and the increase in viscosity often lead to a decrease in printing quality and equipment failure. Adding polypropylene wax can effectively reduce the generation of static electricity, reduce the increase in viscosity, and improve the stability and operability of ink.

Overall, polypropylene wax has various functions in ink, such as thickening, providing gloss and lubrication, improving wear resistance and durability, adjusting rheological properties, anti-static and anti adhesive properties. It provides important guarantees for the performance and quality of ink, making it more suitable for printing processes and improving the quality and effectiveness of printed products. In practical applications, it is necessary to select and control the amount of polypropylene wax added reasonably based on specific printing requirements and ink formulas to achieve the best printing effect.
