Descriptions of PE Wax

Polyethylene wax is a synthetic thermoplastic polymer derived from polyethylene, known for its excellent hardness, low molecular weight, and compatibility with various polymers. It is widely used in industries such as plastics, coatings, adhesives, rubber, and cosmetics due to its lubrication, dispersing, and surface-modifying properties.

What is Polyethylene Wax?

Polyethylene wax (PE wax) is a fine, solid polymer produced from low molecular weight polyethylene. Depending on production methods, it can be in powder, granule, or pellet form. It offers properties such as high thermal stability, excellent chemical resistance, and low shrinkage, making it an essential additive in industrial processes.

Chemical Formula: (C₂H₄)ₙ
Appearance: White to yellowish powder or granules
Melting Point: 110 – 130°C (varies by grade)
Density: 0.92 – 0.97 g/cm³
Solubility: Insoluble in water, soluble in hydrocarbons

Types and Grades of Polyethylene Wax

PE Wax is available in several grades depending on molecular weight, density, and functionalization. Choosing the right grade ensures optimal performance for specific industrial applications:

High-Density Polyethylene (HDPE) Wax

• • Description: Harder wax with high molecular weight and density.

  • Applications: Ideal for extrusion, molding, and as a processing aid in plastics. Provides excellent wear resistance and stability at elevated temperatures.

Low-Density Polyethylene (LDPE) Wax

• • Description: Softer wax with low molecular weight and flexibility.

  • Applications: Commonly used in coatings, adhesives, and as a dispersing agent. Improves flow and surface finish in low-viscosity formulations.

Oxidized Polyethylene Wax

• • Description: Polyethylene wax chemically modified with polar groups to enhance compatibility and adhesion.

  • Applications: Used in PVC processing, inks, coatings, and masterbatches. Enhances pigment dispersion, adhesion, and surface smoothness.
