A propylene glycol, propanediol basic overview Product name: 1,2-propanediol; α - propylene glycol; methyl glycol products English name: 1,2-Propylene glycol, 1,2-propanediol formula: HOCH2CH (OH) CH3 ; C3H8O2 Molecular Weight: 76.1 CAS Number: propylene glycol: When various unsaturated polyesters from uncured low viscosity to high viscosity liquids, various additives added after the heat curing, after curing Serve rigid or resilient plastic, may be a 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 method, is painted in a good mold release agent to spray a layer of resin, holes and a layer of reinforcing material production of propylene glycol, crowding out the bubbles and then repeat the operation to the desired thickness, and finally cured off mode. ② lamination method, is the production of glass cloth impregnated after pouring glycol unsaturated polyester, by laminating 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, sanitary ware and chemical toilet facilities and pipelines.
