LUCANT™ has good compatibility with EPDM since its chemical structure is similar to EPDM. Therefore, LUCANT™ can be used as a good flexibilizer of EPDM.
EPDM compounds with LUCANT™ show lower compression set and higher tensile strength at high temperature than those with mineral oil.
APPLICATION
- Heat-resistant conveyor belts
- Automotive wire harnesses
Defoaming properties
LUCANT™, with non-polarity and wide range of viscosity grades, performs as an excellent defoamer in urethane and epoxy paints because of a good balance of incompatibility and dispersibility.
APPLICATION
- Defoamer for paints and coating materials
Hygiene
LUCANT™ does not have any impurities, aromatic and naphthenic components.
APPLICATION
- Food containers
- Medical materials
Sliding properties
*Reference standard
Ring abrasion test : JIS K 7218:1986
LUCANT™ reduces kinetic friction coefficient and abrasion loss, which improves sliding properties of engineering plastics such as polyamide and polyacetal.
APPLICATION
- Sliding materials for motor vehicles, OA equipment and household appliances
Low-temperature properties
Viscoelasticity — storage modulus G’ and tanδ —
[ Formulation ] EPDM (100) / flexibilizer (40) / carbon (50)[ Crosslinking ] Sulfur crosslink
*Reference standard
Viscoelasticity : K 7244:2007 (ISO 6721-7:1996)
LUCANT™ improves flexibility of EPDM and TPS compounds at low temperature. In particular, LUCANT™ can reduce storage modulus and glass transition point compared with mineral oil, which is because LUCANT™ is amorphous and shows low glass transition point.
APPLICATION
- Automotive weather strips
- Fuel cell gaskets
- Automotive hoses
Wear resistance
DIN abrasion loss
[ Formulation ] EPM (100) / flexibilizer (15) / carbon (50)[ Crosslinking ] Peroxide crosslinking
*Reference standard
DIN abrasion : JIS K 6264-2 (ISO 4649:2002)
LUCANT™ can enhance wear resistance of EPDM compounds compared with mineral oil.
APPLICATION
- Industrial rollers
- Heat-resistant conveyor belts
- Wires and cables
Roll and extrusion processability
LUCANT™ shows the following advantages because it can be entangled with EPDM molecular due to its higher molecular weight than mineral oil: 1st advantage is better roll processability. Unvulcanized EPDM compound with LUCANT™ is more sticky on mixing roll since it has higher tackiness. 2nd advantage is the improvement of surface smoothness of extruded products.
APPLICATION
- Heat-resistant conveyor belts
- Industrial rollers
- Automotive weather strips

*Reference standard
Permanent elongation : JIS K 6273:2018 (ISO 2285:2013)
LUCANT™ has good compatibility with SEBS since its chemical structure is similar to ethylene-butene block of SEBS. Therefore, LUCANT™ can be used as a good flexibilizer of SEBS. LUCANT™ can improve compression set and permanent set of TPS compounds compared with mineral oil.
APPLICATION
- Medical seals and tubes
- Food-contact seals and tubes

*Reference standard
Viscoelasticity : JIS K 7244:2007 (ISO 6721-7:1996)
LUCANT™ improves the damping properties of EPDM compound at room temperature due to higher tanδ value than mineral oil.
APPLICATION
- Dampers for motor vehicles and household appliances
Adhesiveness
LUCANT™ increases flexibility of adhesive, which improves adhesive strength and low temperature adhesion properties.
APPLICATION
- Hot melt adhesives
- Heat sealants
- Ink binders
