Low molecular weight polyolefin


Hi-WAX comprises a low molecular weight polyethylene (PE) manufactured by direct polymerization, a technique developed by Mitsui Chemicals, Inc. on the basis of Ziegler polymerization technology, and low molecular weight polyolefin made by a thermal cracking process.

Hi-WAX is more stable in quality than other synthetic and natural waxes, and a wide variety of grades are commercially available. So, these grades are being used for a broad range of applications, including those in high-technological areas such as toners for plain paper copying and film condensers as well as traditional uses inclusive of pigment dispersants, slip agents and mold release agents for the molding of various synthetic resins, modifiers for printing ink and paints, aids for textile treatment, etc.

Each grade of Hi-WAX possesses distinguished characteristics which can effectively function by their proper use.

An assortment of various types of Hi-WAX: High-density polymerization type, low-density polymerization type, acid-value type, acid-modified type, special monomer-modified type, low-density PE-cracked type, and PP-cracked type.

Along with properties such as releasability, viscosity adjustment, compatibility, slip properties and surface medification properties, more than 30 grades are opening up the possibilities of their use in new fields through proper use of these properties and grades.

Hi-WAX is very stable quality compared with that of natural and synthetic waxes, so that our wax is widely applicable to various uses in many areas.

What is WAX?

  • Solid / semisolid and brittle organic substance at room temperature.
  • Low melting point (less than 150℃) and low melt viscosity.
  • Crystalline and low molecular weight (300-10000) resin.


Higher crystallinity

Higher melting and softening points compared with natural and other synthetic waxes.

Excellent heat resistance and thermal stability

Excellent chemical resistance and electrical insulation properties.

Good affinity to polar polymers, inorganic chemicals and metals.

Easy to pulverize.


Pigment dispersant, Release agent for injection molding, Abrasion resistance of printing ink, Textile treatment agent, Slip agent for PVC, Release agent for toner.
