KOREOX A series (50% of EO Random copolymer)
- KOREOX A series is a copolymer of Ethylene/ Propylene Oxide to be water soluble, and has outstanding lubricity to be used as the soluble lube base oil for grinding oil and the lube base oil for gear oil or refrigerating machine oil.
● Features
▶ Lubricity – Has outstanding lubricity that can be compared with mineral oils or other synthetic lubricants.
▶ Water solubility – It is easily dissolved in water of room temperature
▶ Stability – Has thermal & chemical stability, and has outstanding oxidation stability.
▶ Reverse solubility –It is dissolved easily in cold water, but shows reverse solubility at the cloud point or higher to be separated of hydrophilic group and oleophilic group.
