Oxidized Polyethylene Wax（OPE WAX）

Oxidized polyethylene wax is also known as OPE, is obtained by oxidation of polyethylene wax. Its molecules have polar groups like carbonyl groups and hydroxyl groups, a property which increases the compatibility with fillers, pigments, and polar resins. OPE can be used as an internal lubricant and external lubricant. Currently Qingdao East International Corp. has LDPE OPE Wax – EP629 and HDPE OPE Wax – EP316. They are both oxidized by thermal cracking PE wax.

Oxidized Polyethylene Wax (OPE Wax) – Product Introduction

1. Product Overview

Oxidized Polyethylene Wax (OPE Wax) is a functional wax produced by air oxidation of polyethylene (PE) at high temperatures. It contains polar groups (e.g., -COOH, -OH), combining the lubricity of traditional waxes with excellent compatibility, making it widely used in plastics, coatings, inks, and other industries. 

2. Key Features

Superior Lubrication – Reduces friction during processing, improving production efficiency. 

Excellent Dispersion – Ensures uniform distribution of pigments and fillers for enhanced color consistency. 

Improved Compatibility – Polar groups enhance bonding with non-polar materials (e.g., PVC, rubber). 

Thermal Stability – Melting point typically 100-120°C, suitable for high-temperature processing. 

Eco-Friendly & Safe – Complies with RoHS, REACH, and other international regulations.
