MOQ (Minimum Order Quantity): 230kg drum trial, bulk ≥20MT IBC tank
Appearance: Colorless transparent viscous liquid, no suspended impurity
Our coolant-grade ethylene glycol adopts high-efficiency continuous rectification refining technology, with strictly controlled moisture, organic acidity and trace impurity index to greatly reduce corrosive components inside finished coolant formulations. Thanks to its unique molecular structure, the product owns prominent low freezing point and high boiling point physical features, which can effectively protect automobile engine water tank, radiator and whole circulating pipeline from frost cracking under ultra-low temperature environment and avoid pipeline vaporization boiling in high-temperature working conditions. Every batch of finished liquid goes through full laboratory inspection before leaving factory to guarantee stable and consistent quality for downstream coolant blending factories.
