Hi-WAX™

Low molecular weight polyolefin

Applications detail

Lubricant for PVC, pigment dispersant, releasing agent for engineering plastics and toner

Overview

Hi-WAX™ is a brand of polyethylene wax made by direct polymerization of ethylene, propylene and butene, developed by Mitsui Chemicals based on its unique Ziegler catalyst polymerization technology.
It is used in a broad range of applications, including pigment dispersants, slip agent and mold release agents for molding resins, modifiers for ink and paints, aids for textile treatment and film capacitor materials.

What is Hi-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 (300-10,000) 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 with polar polymers, inorganic chemicals and metals.
Easy to pulverize.
Compatibility

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

Inquiries related to Safety Data Sheets (SDS)

High-density type

High hardness and softening point due to high density and crystallinity.

Low-density type

Low density and crystallinity that are attributable to low hardness and softening point.

Acid-value type

Good affinity with polar polymers, inorganic chemicals, metals, etc. Emulsifiable (High Acid-value grades).

Acid-modified type

Reactive with alcohols, amines, isocyanates, oligomer with epoxy group, etc.

Filler dispersant
Uses

Dry blend resin, filler and High wax, and then melt compound with an extruder.

Availability

Fillers covered with the modified low molecular weight polyolefin can disperse uniformly in the matrix base resin.
It leads to the excellent balance of mechanical and surface properties.

Recommended grades

1105A, 220MP, 4202E

hiwax_02e.jpg
Pigment dispersant
Uses

Add Hi-WAX™ and pigment to the three-roll-mill to make up the color base.

Availability

It is possible to manufacture high content color master batches because Hi-WAX™ is compatible with pigment and expresses excellent kneading behavior into the higher shear of the extruder.

Recommended grades

PE/PP: 420P, 720P
PVC: 320MP, 4202E

Pigment Dispersant
Slip agent for PVC
Uses

Add PVC powder, stabilizer, calcium, calcium stearate and Hi-WAX™ to the twin screw extruder.

Availability

It is possible to express excellent slip properties and prevent the degradation of PVC because Hi-WAX™ affects the area between the surface of the molder and melting PVC.

 

Extrusion: Saving power consumption and increasing productivity.
Injection: Improving the appearance of the molding.

Recommended grades

Rigid PVC(Pipes, Fittings), Soft PVC(Wire & Cable, Sheets): 220MP, 4202E

hiwax_03e.jpg
Textile treatment agent
Uses

Disperse Hi-WAX™ in hot water to make up wax emulsion. Immerse textiles in the emulsion to attach wax to the surface of the textile, then dry heat.

Availability

It is possible to improve high-speed sewing, tear strength and texture.

Recommended grades

Shrink-proof: 4202E, 4052E
Sewing improvement: 4052E
Texture improvement: 1105A, 2203A

Texrile Treatment Agent
Release agent for injection molding
Uses

Add pellets of ABS, PS, etc. and Hi-WAX™ to the injection molder.

Availability

It is possible to express excellent releasability and improve the molding cycle and extrusion properties such as die maintenance.

Recommended grades

PC, PBT, PA: 405MP, 720P, 800P
ABS: 200P, 400P, 220MP
