What raw materials are used for unsaturated resins?
Thread Content
as well as its molecular formula and chemical properties.
What does the original poster mean by that topic? The synthesis of unsaturated resins? Which one? Could you be more specific?
There are many grades of unsaturated resins; I’m not sure which one you intend to produce. Please be more detailed.
Please explain its classification and typical representatives.
Classification of unsaturated polyester resins Based on their structure, unsaturated polyester resins can be divided into ortho-phenylenetype, meta-phenylenetype, para-phenylenetype, bisphenol A type, vinyl ester type, etc； Based on their performance, they can be classified into general-purpose, corrosion-resistant, self-extinguishing, heat-resistant, low-shrinkage types, etc ； Based on their primary uses, they can be divided into two main categories: resins for fiberglass-reinforced plastic (FRP) and resins not used for FRP. Fiberglass-reinforced plastic products refer to various items made by using resin along with glass fibers and their derivatives as reinforcing materials; these are also known as fiber-reinforced plastics (abbreviated as FRP or fiberglass-reinforced plastic) ； Non-fiberglass products are various items made by mixing resin with inorganic fillers or by using the resin alone; they are also known as unreinforced fiberglass products. Classified by specific specialized types, they include winding resin, spraying resin, RTM resin, pultrusion resin, SMC resin, BMC resin, flame-retardant resin, food-grade resin, corrosion-resistant resin, air-drying resin, Plexiglass resin, resin for crafts, button resin, agate resin, artificial stone resin, highly transparent resin, crystal resin, and putty resin, among others. As anti-aging, flame-retardant coatings for FRP surface decoration, heat-resistant coatings, spray coatings, mold coatings, crack-resistant coatings, radiation-curable coatings, highly wear-resistant coatings, and more.
