Propylene glycol: various uncured unsaturated polyester is from low to high viscosity liquids, various additives after heat curing, after curing a rigid or resilient plastic Serve propylene rubber, may be transparent or opaque. Unsaturated polyester main purpose is made of glass fiber reinforced fiberglass, plastic is reinforced one of the main varieties. It's shaping methods are: ① Hand Lay-propanediol, is painted in a good mold release agent to spray a layer of resin, holes and a layer of reinforcing material, crowding out the bubbles and then repeat the operation to a desired thickness, and finally cured stripping . ② lamination method is to pour a glass cloth impregnated after unsaturated polyester glycol prices by stacking cured by hot pressing. It has excellent tensile strength and impact toughness, relative density, good thermal and electrical insulation properties, and good light, weather, acid and sound insulation properties, the price is much cheaper off than epoxy fiberglass, it is widely for the manufacture of radomes, aircraft parts, car shell, small boats, transparent corrugated board and other building materials propylene glycol polyester resin, washing utensils and chemical sanitation equipment and pipelines. Propylene glycol is unsaturated polyester, an important raw material epoxy resin, polyurethane resin, the amount of this area accounts for about 45% of the total consumption of propylene glycol, which is used extensively for unsaturated polyester surface coatings and reinforced plastics. The viscosity and moisture absorption of propylene glycol, and non-toxic, and thus in the food, pharmaceutical and cosmetic industry is widely used as a hygroscopic agent, antifreeze agents, lubricants and solvents. In the food industry, propylene glycol and propylene glycol fatty acid esters of fatty acids produced by the reaction, mainly for food emulsifier; Propylene glycol is an excellent solvent seasoning and coloring. Propylene glycol in the pharmaceutical industry for manufacturing various types of commonly used ointments, salves solvent, softener and excipients and the like, due to propylene glycol with various spices have good mutual solubility, and thus the solvent and the softening agent for cosmetics and the like. Propylene glycol is also used tobacco moisturizing agents, preservatives, food processing equipment, lubricants and food marking ink solvents. An aqueous solution of propylene glycol is effective cryoprotectant. Propylene glycol polyester resin _ Wei Connaught Chemical (certified) _ glycol provided by Qingdao Wei Connaught Chemical Co.
