Antifreeze is dedicated 99.9% high purity ethylene and other chemical raw materials. Professional production factory direct, spot ethylene supply stability, quality assurance; price advantage, the cash supply. The physical properties of ethylene glycol: CAS No. 107-21-1 Chinese name English name glycol Ethylene glycol, Mono ethylene glycol, MEG oil grade high purity ethylene manufacturers, EG English Synonyms:. Glycol, 1,2-ethanediol Alias ??glycol formula C2H6O2; structural formula: HOCH2CH2OH molecular weight 62.07 Melting point -13.2 ℃ Boiling point: 197.85 ℃ Density Relative density (water = 1) 1.1155 (20 ℃); the relative density (Air = 1) 2.14 Appearance colorless, odorless , sweet, viscous liquid vapor pressure 6.21kPa / 20 ℃ Flash point: 111.1 ℃ Viscosity: 25.66mPa.s (16 ℃) Surface tension: 46.49 mN / m (20 ℃) ??Flash point: 118 ℃ Wong Road Guangzhou City Limited distribution of ethylene glycol, diethylene glycol, propylene glycol, DOP, methylene chloride, styrene, probucol, vinyl acetate, acrylic, isooctylacrylate fat variety, reasonable prices. Guangzhou Wong Lu Da Co., strength, credit, keep the contract, to ensure product quality, variety principles of operating characteristics and puerile, and win the trust of our customers. Wong Road Chemical is a professional company engaged in chemical raw materials, the main products for antifreeze, car care, ink, Rihuayuanliao, coatings, printing, resins, adhesives and the like. Main products: ethylene glycol, propylene glycol, diethylene glycol, triethylene glycol, butyl acetate, ethyl acetate, triethanolamine security, anti-white water, cleaning agents, DMF, DOP oil grade ethylene glycol, and other raw materials. Ethylene glycol is a colorless, slightly viscous liquid boiling point is 197.4 ℃, freezing point is -11.5 ℃, can be mixed with water in any proportion. Due to changes in the vapor pressure of the cooling water, the freezing point significantly reduced after mixing. Degree of reduction within a certain range with the content of the ethylene glycol increases. When ethylene glycol content of 60% oil grade glycol manufacturer delivery, the freezing point can be lowered to -48.3 ℃, exceeds this limit, the freezing point but to rise. Glycol antifreeze easy to generate acidic substances in use, have a corrosive effect on metal. Glycol toxic, but because of its high boiling point, does not produce steam to be inhaled and cause poisoning. Ethylene glycol absorbent, storage containers should be sealed to prevent water absorption after overflow. Imported green oil grade glycol, Chemical Wong Road, Mentougou oil grade glycol provided by the Guangzhou Chemical Co., Ltd. Wong Road. Guangzhou Wong Road, Chemical Co., Ltd. (www.wangluda.com) (www.wangluda.com) is a leader in Guangzhou, cosmetic raw materials, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum to meet customer needs.
