PP WAX TDS:

Part One: Polypropylene Wax (PP Wax) – A Comprehensive Introduction

What is PP Wax?

Polypropylene Wax (PP Wax) , scientifically known as low molecular weight polypropylene, is a synthetic polymer wax produced through the controlled polymerization or thermal degradation of polypropylene. Unlike its counterpart polyethylene wax (PE wax), PP Wax is characterized by its higher melting point, superior hardness, and exceptional thermal stability, making it an indispensable additive and processing aid in numerous industrial applications.

 

PP Wax belongs to the broader family of polyolefin waxes, which also includes polyethylene wax (PE Wax). While both are derived from polyolefin polymers, PP Wax exhibits distinct properties that set it apart. As Westlake Chemical notes in their EPOLENE® product line, these specialty polymers—also known as polyethylene wax or polypropylene wax—are available in a variety of molecular weights, melting points, and densities. The EPOLENE® product family includes three main types: coating "C" grades, nonemulsifiable "N" grades, and emulsifiable "E" grades, each designed for specific formulation requirements.

 

The molecular structure of PP Wax consists of propylene monomer units arranged in a polymer chain with a relatively low degree of polymerization. The average molecular weight of PP Wax typically ranges from approximately 5,000 to 10,000 mw. This low molecular weight, combined with the isotactic or atactic configuration of the polymer chains, imparts unique physical and chemical characteristics that distinguish PP Wax from higher molecular weight polypropylene resins.

 

Chemical and Physical Properties

The fundamental properties of PP Wax can be understood through its technical data sheet (TDS) parameters, which vary depending on the specific grade and manufacturing process:

 

Thermal Properties:

 

Melting Point: PP Wax exhibits a high melting point ranging from 130°C to 162°C, significantly higher than polyethylene wax by approximately 30°C or more. This high melting point makes PP Wax suitable for high-temperature processing environments where other waxes would degrade or lose effectiveness.

 

Softening Point: The high softening point of PP Wax (typically 150-160°C) ensures dimensional stability and performance retention under elevated temperature conditions.

 

Thermal Stability: Premium grades of PP Wax, such as Mitsui Chemicals' HI-WAX NP055, demonstrate excellent thermal stability up to 300°C, supporting high-temperature processing including extrusion and injection molding.

 

Rheological Properties:

 

Melt Viscosity: PP Wax exhibits low melt viscosity, typically ranging from 150 to 400 mPa·s at 170°C, depending on the specific grade. This low viscosity enables superior flow characteristics and enhanced processability.

 

Density: The density of PP Wax generally falls between 0.87 and 0.97 g/cm³ at 23°C, with most commercial grades around 0.89-0.91 g/cm³.

 

Mechanical Properties:

 

Hardness: PP Wax is characterized by high hardness and low needle penetration values (typically less than 2 dmm at 25°C), indicating excellent surface hardness and abrasion resistance.

 

Particle Size: Micronized grades of PP Wax, such as Deuteron Wax PP, feature fine particle size distribution with average particle sizes around 5 microns, d50 of 6.6 microns, and d90 of 14.4 microns. This fine particle size enables easy dispersion in various systems.

 

Chemical Properties:
