Propanediol Price, Wei Connaught Chemical (certified), propylene glycol provided by Jilin Chemical Co., Ltd. Qingdao Wei promise. Qingdao Wei Connaught Chemical Co. (www.qdweinuo.com) is specialized in the "phenol, aniline, ethylene, n-butanol, isobutanol, n-propanol, isopropanol, methanol," the business, the company adhering to the "integrity management, service intentions, "the idea, to provide you with the highest quality products and services. Welcome to inquire! Contact: Feng Zhongying. Propylene glycol or unsaturated polyester, epoxy resin, polyurethane resin important raw material propylene glycol manufacturer, the amount in this area accounted for about 45% of the total consumption of propylene glycol production, such a large number of unsaturated polyester used in surface coatings and reinforced plastics in the food industry production glycol, propylene glycol and fatty acids, propylene glycol fatty acid esters produced by the reaction, mainly used as food emulsifiers propylene glycol: Features edit process performance. This is the greatest advantage of the unsaturated polyester resin. Propylene glycol can be cured at room temperature and atmospheric pressure forming, flexible process performance, especially for large-scale manufacture of FRP products and live. After curing resin good overall performance. Mechanical properties of epoxy resin slightly lower, but better than the phenolic resin. Corrosion resistance, electrical properties and flame retardancy by selecting the appropriate grade of resin to meet the requirements, the resin is light in color, may be made of transparent products. Varieties, adapt to a wide, low prices. The disadvantage is that the shrinkage upon curing is large, short shelf life.
