Spherical HDPE Micronized Wax is fine spherical HDPE wax powder designed as a direct replacement for Luwax AF30. Its regular spherical particle geometry improves dispersion behaviour inside solvent‑based ink systems. Apart from enhancing rub‑resistance and slip properties on printed ink film, this micronized wax also provides valuable anti‑settling effect for pigment‑rich flexo and gravure inks. It maintains good thermal stability during ink manufacturing and storage, and is widely used in solve

Product Detail

Product Overview

Spherical HDPE Micronized Wax (CAS 9002‑88‑4, Luwax AF30 Equivalent) is synthetic high‑density polyethylene refined into uniform spherical micron‑size powder. Distinct from irregular crushed wax powder, the spherical particle structure helps to reduce sedimentation tendency in high‑pigment solvent‑based ink systems. While incorporated into flexo and gravure inks, the wax gradually migrates to the printed surface after drying, forming a thin lubricating protective layer. This improves rub‑resistance and scuff‑proof performance of printed artwork. It acts as a reliable imported substitute for Luwax AF30 within the solvent‑based printing ink industry.

Key Features

Functional equivalent to Luwax AF30 for cost‑effective imported grade substitution
Uniform spherical particle shape, good free‑flow powder characteristics
Remarkable anti‑settling property, reduces pigment sedimentation inside solvent‑based ink
Significantly improves rub‑resistance, scuff resistance and surface slip of printed ink layer
Excellent heat stability during ink grinding, dispersing and processing
Good compatibility with various solvent‑based ink resin binders
Optimized formulation performance for flexographic and gravure printing applications

Technical Specification

Chemical Name: Spherical HDPE Micronized Wax
CAS Number: 9002‑88‑4
Appearance: White fine spherical powder
Melting Point: 126‑132℃
Particle Size: Custom micron range
Equivalent Grade: Luwax AF30

Application Fields

Solvent‑based flexographic printing inks: improve rub‑resistance and inhibit pigment settling
Solvent‑based gravure printing inks for packaging printing: protect printed surface against abrasion
Industrial solvent‑borne surface coatings requiring slip and anti‑sedimentation performance
Special printing varnishes for flexible packaging

Usage Recommendation

Recommended dosage ranges from 0.4‑3.2 % by total ink or coating formulation weight. Add the wax powder at the grinding or high‑speed dispersion stage of ink production. Adequate dispersion is critical for obtaining stable anti‑settling and rub‑resistant effect. It is strongly suggested to carry out laboratory formulation trials prior to large‑scale manufacturing.

Storage & Handling

Store sealed sacks in a dry, well‑ventilated warehouse. Keep away from direct sunlight and high‑temperature heat sources. Prevent moisture absorption. Take precautions against static electricity and dust accumulation during material handling. Reseal sacks immediately after each use.

Safety Notice

This micronized wax powder is exclusively intended for industrial ink and coating formulation, not for food or cosmetic usage. Avoid inhalation of fine dust particles. Wear dust‑proof mask, safety goggles and protective gloves during operation. Refer to the corresponding MSDS for complete safety information.
