The role of Wei Connaught Chemical, Qingdao propylene glycol manufacturer, propylene glycol, propylene glycol provided by Wei Connaught Chemical. We are Qingdao Wei Connaught Chemical Co. (www.qdweinuo.com) at: Qingdao, Shandong specialized in: phenol, aniline, ethylene, n-butanol, isobutanol, n-propanol, isopropanol, methanol, propylene glycol is not unsaturated polyester, an important raw material epoxy resin, polyurethane resin, the amount of this area accounts for about 45% of the total consumption of about propylene glycol, which is used extensively for unsaturated polyester surface coatings and reinforced plastics. Propylene glycol, propylene glycol, viscosity and good moisture absorption effect, and non-toxic, and thus in the food, pharmaceutical and cosmetic industry, widely used as a hygroscopic agent, antifreeze agents, lubricants and solvents. Glycol effect the reaction of propylene glycol and fatty acid in the food industry, propylene glycol fatty acid esters, mainly used as food emulsifiers; Propylene glycol is a good solvent for condiments and pigment. Propylene glycol used in the pharmaceutical industry for the manufacture of various types of ointments, salves solvents, softeners, and excipients, etc., because propylene glycol has a good miscibility with a variety of perfumes, cosmetics, and thus also used as solvents and softening agents and the like. Propylene glycol is also used as wetting agents in tobacco, fungicides, lubricants, and food processing equipment, food marking ink solvents. Aqueous glycol anti-freeze agents are effective. Propylene glycol is also a new type of manufacturing polyester fibers with excellent performance polyethylene terephthalate (PTT) is an important monomer material. PTT fiber compared with PET (commonly known as polyester, Dacron, chemical name polyethylene terephthalate), PBT (commonly known as Dacron polyester, chemical name poly butylene terephthalate) fiber has better performance propylene glycol, both PET and PBT high performance and easy processability. The polyester fiber compared with the conventional PET fiber, which is a soft segment portion, rather than ethylene glycol, and therefore the soft segment portion of its carbon - carbon chain is longer, which makes the fiber itself has an elastic, soft
