Micronized wax for printing ink

1. Functions in Printing Inks:

Abrasion & Scratch Resistance:Forms a protective layer on the ink surface, reducing wear during handling.

Slip Improvement:Reduces friction, preventing blocking (sticking) of printed surfaces.

Matting Effect:Can adjust gloss levels (depending on particle size).

Rub Resistance:Prevents ink from smudging during post-printing processes.

Water & Chemical Resistance:Enhances durability in wet or harsh environments.

2. Common Types of Micronized Waxes for Inks:

Polyethylene (PE) Wax:Most widely used; offers excellent rub resistance and slip.

Polypropylene (PP) Wax:Higher hardness, used for tougher abrasion resistance.

PTFE-modified Waxes:Adds exceptional lubricity (e. g. , for high-speed printing).

Carnauba Wax (Natural):Used for high-gloss inks and food-contact applications.

Fischer-Tropsch Wax:Synthetic alternative to carnauba with consistent quality.

Paraffin & Microcrystalline Waxes:Lower-cost options for specific applications.
