Ethylene Glycol Industrial Grade ≥99.5% is one of the most consumed bulk glycol products in global petrochemical industry chain, and Linkwin implements full rectification purification and batch full-index inspection system for ethylene glycol product, guaranteeing minimum 99.5% main content, ultra-low diethylene glycol, triethylene glycol, aldehyde and water impurities, perfectly matching high-demand PET polycondensation polymerization production requirements and high-grade antifreeze formulation standards. Excessive diethylene glycol impurity will seriously reduce PET intrinsic viscosity, cause yellowing and poor mechanical properties of polyester products, while high impurity glycol will lead to corrosion and scaling inside engine cooling system for antifreeze use; our rigorous impurity control mechanism fundamentally avoids these formulation risks for downstream manufacturers. The finished ethylene glycol has strong water miscibility, low freezing point, moderate boiling point and stable chemical inertia, widely used as freezing point depressant and heat conduction medium in thermal system circulation, as well as polycondensation monomer for polyester polymer synthesis.

In downstream industrial application layout, the largest consumption direction is polyester industry: ethylene glycol undergoes polycondensation reaction with purified terephthalic acid (PTA) to synthesize bottle-grade PET resin, textile polyester staple/filament fiber and BOPET polyester film, covering packaging, textile, new energy photovoltaic backsheet film massive downstream market. Second major application is automotive and industrial antifreeze production: blended with corrosion inhibitor, deionized water and buffer additives to formulate engine coolant, winter pipeline antifreeze, central air conditioning circulating freeze-proof fluid and industrial refrigeration heat transfer medium, effectively preventing pipeline and equipment frost cracking under low-temperature environment. In addition, ethylene glycol serves as high-boiling solvent, humectant and intermediate raw material for alkyd resin, brake fluid, coating formulation, printing ink and fine chemical synthesis. Many overseas polyester and antifreeze manufacturers frequently complain about high diethylene glycol content, unstable index and easy moisture absorption from inferior glycol suppliers; our sealed anti-hygroscopic packaging and pre-shipment strict testing completely eliminate these quality defects, stabilizing your finished product yield and market competitiveness.
