Basic Information

LUCANT™ is an ethylene/α-olefin oligomer. It is a hydrocarbon-based synthetic oil containing no polar group. The synthetic oil with this structure is a unique product commercialized by Mitsui Chemicals for the first time in the world.

LUCANT™ as a base oil or a viscosity modifier contributes to an improvement in the functions of the lubricants that are required to have heat resistance, low-temperature resistance and high shear stability.

LUCANT™ as an additive to rubbers, resins, paints and coatings, etc. provides new functions such as processability, flexibility, heat resistance, low-temperature properties, sliding properties and defoaming properties, among other properties.


LUCANT™ is a colorless, transparent, viscous liquid. A full lineup of LUCANT™ grades that covers a broad range of viscosity is available.

Heat resistance

LUCANT™ is stable against heat. It is a material with high flash and ignition points.

Chemical resistance

LUCANT™ is chemically stable and shows excellent chemical resistance, exhibiting little or no quality change when exposed to acids and alkalis.

Lubricity improvement

LUCANT™ is a superb lubricating material that is characterized by a broad operating temperature range, excellent shear stability, excellent thickening efficiency, thick oil film thickness and a low pour point, among other properties.

Lubricant application, Rubber & Elastomers application as plasticizer, flexibilizer and process aid, Resin application as flexibilizer, slip agent and sliding property improver, Paint and coating application as defoamer, and other application (tackifier, adhesive, ink , cosmetics, heat carrier, specialty chemicals and solvents)

Lubricant application

LUCANT™ is a superb lubricating material that has the characteristics of a broad operating temperature range, excellent shear stability, excellent thickening efficiency, thick oil film thickness and a low pour point, among other important properties. Moreover, LUCANT™ provides higher functions and improves the fuel saving performance of lubricants that are required to show heat resistance and low-temperature resistance, such as gear oil for automotive driveline systems including transmissions and differential gears, and lubricants and grease for industrial use.

Rubber and elastomer application

When LUCANT™ is used as a plasticizer, a flexibilizer or a processing aid for rubbers and elastomers such as EPDM and thermoplastic styrene-based compounds, it endows them with flexibility, good processability, high heat resistance, good low-temperature properties, damping properties, antifouling characteristics and low migration properties, among other properties. The LUCANT™-using rubbers and elastomers are applicable to a wide variety of automotive parts (damping materials, sealing materials, etc.) and industrial parts (heat-resistant conveyer belts, OA rolls, etc.) LUCANT™ also demonstrates a high effect as a defoaming agent for thermosetting elastomers (urethane, epoxy, etc.).

Resin application

LUCANT™ endows a broad range of thermoplastic resins (POM, ABS, etc.) with satisfactory sliding properties, low-temperature properties, flowability and flexibility. Thermoplastic resins using LUCANT™ can be applied to resin gears and bearings that are required to have sliding properties.

Paint and coating application

>LUCANT™ demonstrates its effect as a defoaming agent for paints. It is particularly effective for paint and coatings based on solvent-based and non-solvent-based urethane and epoxy. A satisfactory appearance can be obtained with the addition of a small amount of LUCANT™. LUCANT™ contains no silicone or aromatic solvent.

Other application
