Enhancing Rub Resistance and Print Clarity in Solvent-Based Inks with PE and PTFE Waxes

In the printing industry, ink performance determines both product appearance and longevity. One of the biggest challenges in solvent-based inks is maintaining high rub resistance and print clarity during high-speed printing and post-handling. This is where polyethylene (PE) and PTFE wax additives deliver exceptional performance.

PE wax provides a smooth, lubricating layer within the ink matrix, which reduces friction and surface abrasion. It effectively prevents smudging, ink transfer, and gloss loss during processing or stacking. PTFE wax, known for its ultra-low coefficient of friction, further enhances slip and scuff resistance—essential for applications like flexible packaging, publication inks, and high-end decorative printing.

Beyond mechanical resistance, wax additives also help maintain ink stability. The fine particle distribution of micronized PE and PTFE wax ensures excellent pigment dispersion and consistent color development. These waxes are compatible with most resin systems used in solvent-based gravure and flexographic inks, making them easy to incorporate during ink grinding or let-down stages.

Another advantage is the control over surface finish. By adjusting wax type and dosage, formulators can achieve different levels of gloss—from matte to semi-gloss—without sacrificing print definition. In addition, the wax surface migration forms a protective microfilm that minimizes blocking and improves slip properties.

At Tianshi, our PE and PTFE waxes are developed for optimal balance between rub resistance and clarity. They are easy to disperse, thermally stable, and suitable for both solvent-based and UV-curable inks. Whether you produce packaging inks, decorative films, or high-speed gravure prints, our wax additives can help you achieve cleaner impressions and longer-lasting results.
