Guangzhou Yang Qing Chemical Co., Ltd. Distribution of propylene glycol, glycerin, triethanolamine, AES, AOS variety, reasonable prices. Guangzhou Yang Qing Chemical Co., strength, propylene glycol imports, credit, keep the contract, to ensure product quality, variety principles of operating characteristics and puerile, and win the trust of our customers. Main: Dow propylene glycol, SKC glycol Appearance: colorless, viscous liquid absorbent stable, almost no odor, slightly spicy melting point (℃): -. 60 Relative density (water = 1): 1.0381 Boiling point (℃): 187.3 ℃ Relative Vapor Density (Air = 1): Refractive index (℃): 1.4326 latent heat of vaporization (KJ / kj): 538.1 critical temperature (℃): 351 Critical pressure (Kpa): 6090 octanol / water Pow parts distribution coefficient: Flash point (℃): 107 Upper explosive limit% (V / V): 12.5 Autoignition Temperature (℃): 421 explosion limit /%(V/V):2.6 Solubility: with water, ethanol , a variety of organic solvents as diethyl ether, chloroform, acetone and other segments of hydrocarbons, chlorinated hydrocarbons, dissolved fat is small, but better than the solubility of ethylene glycol main purposes: Due to the low toxicity in the food industry as spices, food coloring solvents, used as a solvent transfer agents, preservatives, soft vitamin, penicillin in the pharmaceutical industry, also used as a tobacco wetting agents, preservatives, fruit ripening agent, antifreeze and heat carrier, etc. , but also for the manufacture of unsaturated polyester resins, plasticizers, surfactants, etc. .. Guangzhou Yang Qing Chemical Co., Ltd. Distribution of propylene glycol, glycerin, triethanolamine, AES, AOS variety, reasonable prices. Guangzhou Yang Qing Chemical Co., strength, credit, keep the contract, to ensure product quality and content, propylene glycol, variety principles of operating characteristics and puerile, and win the trust of our customers. Main: Dow propylene glycol, SKC propylene glycol, 1,3-propanediol can be replaced, 1, Shantou, propylene glycol, 1,4-butanediol and neopentylglycol intermediates for the production of polyester polyol and a carbon chain extender . Synthesis of phthalic acid with polyethylene terephthalate (PTT), propylene glycol what price, to display than ethylene glycol, butylene glycol monomer synthetic polyethylene terephthalate (PET), better performance polyethylene terephthalate (PBP), etc., is considered a high performance of both PET and PBT of new polyester material and easy workability. PTT is the textile industry, a new type of polyester chemical fiber, is superior to PET and PBT, PET overcome the rigidity and flexibility of PBT, in particular, it has excellent elasticity (tensile elastic recovery of 20% up to 100 %), easy dyeing (atmospheric boiling dye can under no circumstances support), stain resistance, abrasion resistance, low water absorption and good color fastness (UV, ozone, nitrogen oxides), both advantages of polyester, nylon or spandex can be made highly fluffy BCF yarn, composite fibers, carpets, stretch fabric, non-woven fabric for clothing and a variety of potential uses. The 1,3-PDO and terephthalic acid (ester) synthetic polyethylene terephthalate (PTT), the market prospect is broad Shantou glycol | propanediol level | Y-Chemical (quality businessmen) from Guangzhou Yang Qing Chemical Co. company. Road Zhiyuan, temper forward. Guangzhou Yang Qing Chemical Co., Ltd. (www.gzyangqing.com) (www.gzyangqing.com) aims to become and you win symbiosis, strategic partners to move forward, more determined to become the most influential agents of chemical products business, and You leap together, succeed together!
