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, variety of operating characteristics and puerile principle glycol origin, has won the trust of our customers. Main: Dow propylene glycol, SKC glycol of the fiber compared to conventional PET polyester fiber, it's the soft segment portion is propylene glycol instead of ethylene glycol, so it's soft segment portion of the carbon - carbon chain is longer, which makes the fiber itself has elasticity, soft, with as good elongation properties of elastic fibers. In addition to fouling and strong, its performance is better than dyeing nylon, can usually disperse dyeing and printing, without the use of special chemicals, dyeing having dry propylene glycol, crisp characteristics. 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, variety principles of operating characteristics and puerile, and win the trust of our customers. Main: Dow propylene glycol, SKC glycol first developed by the Do Pont company, mainly through strain glycerol fermentation substrate 1,3-PDO, the process at home and abroad are in the research stage. Selection and training of bacteria is the key, the current study is more bacteria are Klebsiella, Clostridium butyric acid, lemon Freund three bacteria strains glycol effect, they have a higher 1,3 PDO conversion and production strength. Some foreign research institutions through the use of gene technology in food-grade propylene glycol, selected bacteria, DNA recombination, to improve the yield of 1,3-propanediol. As a result of the world at present genetically engineered bacteria fermentation production of 1,3-propanediol, only DuPont family, thus DuPont patent application by the relevant technologies and processes were well protected, the formation of a high degree of technical monopoly Dongguan glycol, propylene glycol agency, Yang Qing Chemical (certified merchants) are provided by Jan-Chemical Co., Ltd. in Guangzhou. 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!
