Product Description
Unsaturated polyester resin is the most commonly used type of thermosetting resin, which is generally a linear polymer compound with ester bonds and unsaturated double bonds formed by the condensation of unsaturated dicarboxylic acid with diols or saturated dicarboxylic acid with unsaturated diols. Usually, the polyester condensation reaction is carried out at 190-220 ℃ until the expected acid value (or viscosity) is reached. After the polyester condensation reaction is completed, a certain amount of vinyl monomer is added while hot to prepare a viscous liquid. This polymer solution is called unsaturated polyester resin.
1. Chemical resistance
Unsaturated polyester resin has good chemical resistance and can be used for a long time in corrosive media such as acid, alkali, and salt. This is also one of the reasons why unsaturated polyester resin is widely used in chemical equipment, waste gas treatment, water treatment and other fields.
2. Mechanical strength
Unsaturated polyester resin has high mechanical strength after curing, especially in terms of bending, tensile, and compressive strength. Therefore, it is widely used in the field of manufacturing various structural materials.
3. Plasticity
During the processing, unsaturated polyester resin is prone to forming various shapes, which can be achieved through processes such as molding, compression molding, and stamping. At the same time, it also has good adhesion and is suitable for bonding with other materials.
Unsaturated polyester resin has achieved great success in many industrial fields, such as in the manufacture of windsurfing and yachts in water sports. This polymer has always been at the core of the true revolution in the shipbuilding industry, as it can provide excellent performance and very high flexibility in use.
Unsaturated polyester resins are also commonly used in the automotive industry due to their design versatility, light weight, low system cost, and low mechanical strength.
This material is also used in buildings, especially in the manufacture of cookware, stoves, roof tiles, bathroom accessories, as well as pipes and water tanks.
compounds used in a wide range of industries. The most important, as well as those illustrated above, are:
* Composite materials

Specification
Polyester resin is defined as a polymer obtained through the condensation reaction between polyacids and polyols. The formation of water is a byproduct of this condensation process. Specifically, unsaturated polyester resin is a liquid polymer that is easy to print, and once cured, it can maintain the solid shape in the mold. The item achieved in this way has extraordinary strength and durability.
Unsaturated polyester resin is mainly used in combination with reinforcing materials such as glass fiber, which gives life to polyester resin. Polyester resin is a type of polyester reinforced with glass fiber, known for its name glass fiber. In this case, polyester resin has an array function that guides the forces applied to the material onto the fibers intended to withstand these forces, thereby increasing strength and avoiding product damage.
Liquid unsaturated polyester resin can be combined with or separated from glass fiber, and can be loaded with various sizes of powders or particles. These powders or particles can provide details of rigidity and resistance characteristics, or provide aesthetic quality for imitations of natural marble and stone, sometimes with better results.
