KOREOX W series (75% of EO Random copolymer)


- KOREOX W series is a copolymer of Ethylene Oxide and Propylene Oxides, and it is a substance that can utilize the feature of outstanding lubricity or as the surfactant. KOREOX W series has more outstanding hydrodynamic lubricating characteristics compared to mineral oils or other synthetic lubricants to reduce the abrasion of equipment. In addition, the products are water soluble to be dissolved easily in water of room temperature, but the PAG ingredient is dissociated in high temperature to perform outstanding thermal treatment features
