There are many types of unsaturated polyester resins, including high temperature resistance, fire resistance, light resistance, corrosion resistance, and other unique uses. At this stage, the basic product is general-purpose unsaturated polyester resin. Replacement of polyester for various unique uses).

Unsaturated polyester resin has excellent production and processing performance and simple processing technology. It can be formed in one time. It can be formed at room temperature and pressure, and it can be heated and pressed to dry, and there are no by-products of low molecular structure during the drying process. Produce more uniform products. Because of the outstanding performance of unsaturated polyester resin, it has been widely used to make non-glass fiber reinforced raw materials such as artworks, imitation marble products, polyester paint and so on in recent years.

1. According to the structure of unsaturated polyester resin, it can be divided into o-phthalic type, isophthalic type, p-benzene type, bisphenol A type, vinyl ester type, etc.;

2. According to its characteristics, it can be divided into versatility, anti-corrosion type, self-extinguishing type, high temperature resistant type, low shrink type, etc.;

3. According to its scope of application, it can be divided into two types: FRP resin and non-FRP anti-corrosion resin. To put it bluntly, FRP products refer to various products made of resin with glass fiber and products as raw materials. It is a glass fiber elastomer material (abbreviated as FRP or FRP anticorrosive); non-glass fiber reinforced plastic products are various products made by mixing resin and inorganic fillers or using their own independent applications, also known as non-reinforced fiberglass products .
