Oxidized PE Wax is a modified polyethylene wax with carboxyl and hydroxyl functional groups. It provides both internal and external lubrication, and it is well known for its excellent compatibility and dispersion properties in various thermoplastic and thermosetting systems. It is used in PVC, color masterbatch, printing ink, and coatings.

Mechanism & Features

Good thermal stability and low volatility
Improved pigment dispersion due to polar groups
Enhances melt flow and release properties
Excellent compatibility with polar and non-polar resins
Acts as coupling agent in fillers and pigments

Usage Recommendations

Issue	How Oxidized PE Wax Helps
Poor pigment wetting	Polar groups enhance dispersibility
High friction in processing	Acts as dual (internal & external) lubricant
Incompatibility with fillers	Improves bonding and wetting of surfaces
Uneven gloss or surface defects	Improves surface finish and melt flow

FAQ

Q1: What is the difference between oxidized PE wax and regular PE wax?
Oxidized PE Wax contains polar groups (acid value), improving its compatibility with polar materials and enhancing pigment dispersion.

Q2: Is it suitable for food-contact applications?
No, this product is intended for industrial use only unless specifically certified.

Q3: What is the recommended dosage?
Typically 0.5 – 2.5 phr depending on formulation and application.
