Raw Material Knowledge Popularization:Unsaturated polyester resin is one of the most commonly used types of thermosetting resin. It is a linear polymer formed by the condensation of saturated dicarboxylic acids, unsaturated dicarboxylic acids, and diols."交联"可以翻译为 "crosslinking".Unsaturated Polyester Resin (UPR) refers to a resin solution with a certain viscosity, either as a monomer or diluted with an active solvent. The most significant advantage of unsaturated polyester resin is its wide variety, adaptability, and low cost. It can be used in various applications.Room temperatureCuring under normal pressure, molding under normal pressure, the process performance is flexible, especially suitable for large-scale and on-site manufacturing of glass fiber reinforced plastics. After curing, the resin has good comprehensive performance, and the mechanical properties are slightly lower thanEpoxy resinHowever, it is superior to phenolic resin. Corrosion resistance, electrical performance, and flame retardancy can be met by selecting the appropriate resin grade. The resin has a light color and can be used to make transparent products.
