What kinds of unsaturated resins are there? Common 14 categories to see what you know

With the rapid development of China's economy and the rapid growth of science and technology, people's requirements for the functions and types of materials used in each field have also improved, such as unsaturated resin, which is widely used. Of course, this also stems from its excellent types and functions. Next, let's understand its characteristics and the types of unsaturated resin.

Characteristics of unsaturated resin: unsaturated resin is a kind of thermosetting resin, which is usually formed by condensation of unsaturated dicarboxylic acid, saturated dicarboxylic acid and dicarboxylic alcohol, and is a low-molecular weight polymer with unsaturated double bonds. Its physical state is a viscous flowing liquid. Under the action of initiator, the copolymerization reaction takes place, and its molecules will connect with each other into a three-dimensional network insoluble molecular structure, thus becoming a solid state.

Unsaturated resin has suitable viscosity at room temperature and can be formed at room temperature and pressure. It is also very convenient to construct. It is especially suitable for large and on-site manufacturing of glass fiber reinforced plastic products. It also has good comprehensive properties, reliable mechanical properties and corrosion resistance.

Therefore, the characteristics of unsaturated resin lie in its light weight, good corrosion resistance, excellent electrical properties, unique thermal properties, excellent processing performance, and good designability of materials.

As a common thermosetting resin, unsaturated resin has a wide range of types, mainly including:

1. Winding process unsaturated polyester resin

2. Special resin for vacuum induction process

3. Unsaturated polyester resin for pultrusion process

4. SMC/BMC special unsaturated polyester resin

5. CIPP special resin

6. Corrosion resistant unsaturated polyester resin

7. Unsaturated polyester resin for double-wall tank

8. Flame retardant unsaturated polyester resin

9. Special resin for resin concrete

10. Transparent unsaturated polyester resin

11. Flexible unsaturated polyester resin

12. Bowling special resin

13. Food-grade unsaturated polyester resin

14. Other unsaturated polyester resins
