2,5-Furandicarboxylic acid (FDCA, CAS No. 3238-40-2), as an important bio based chemical, has been widely used in various industrial fields in recent years, especially in the field of polymer materials, which has attracted widespread attention. Unsaturated resin, as a widely used material in composite materials, coatings, adhesives and other fields, is widely used due to its excellent mechanical and processing properties.

2,5-Furandicarboxylic acid (FDCA, CAS No. 3238-40-2) is a dicarboxylic acid compound with two carboxyl groups (- COOH) and one furan ring. This chemical structure makes it an important monomer for preparing various polymers. The furan ring structure endows it with unique reactivity, enabling it to participate in various condensation reactions and generate different polymer materials. In the preparation process of unsaturated resins, 2,5-furandicarboxylic acid can react with different polyols to produce resin materials with high strength, high heat resistance, and good chemical resistance.

1. As an alternative raw material for unsaturated polyester resin

Unsaturated polyester resin (UPR) is a resin material obtained by reacting polyols with unsaturated acids. Traditionally, the production of UPR relies on petrochemical raw materials such as terephthalic acid (PTA) and maleic anhydride. However, with the increasing demand for sustainable chemicals, 2,5-Furandicarboxylic acid (FDCA, CAS No. 3238-40-2) has gradually become a green alternative to terephthalic acid in UPR due to its biobased sources and good chemical properties. It is condensed with different polyols such as ethylene glycol and propylene glycol to produce polyester resins that exhibit excellent mechanical properties and possess similar or even better thermal stability and chemical corrosion resistance than traditional resins.

2. Improve the mechanical properties of the resin

The application of 2,5-Furandicarboxylic acid (FDCA, CAS No. 3238-40-2) in unsaturated resins not only enhances the material's renewability, but also strengthens its mechanical properties. The rigid structure of furan ring endows polyester resin with higher tensile strength and toughness. This makes the resin prepared from 2,5-Furandicarboxylic acid (FDCA, CAS No. 3238-40-2) an ideal choice for many high-performance applications, such as building materials, shipbuilding, and automotive industries. These resins have mechanical properties comparable to traditional resins based on terephthalic acid, and even exhibit better toughness and impact resistance under certain conditions.

3. Improve the heat resistance and thermal stability of the resin

The thermal stability of unsaturated polyester resin is a key factor in many industrial applications. Due to the high thermal stability of its furan ring, 2,5-Furandicarboxylic acid (FDCA, CAS No. 3238-40-2) enables resins based on this compound to exhibit good heat resistance at high temperatures. Compared with traditional petrochemical based resins, the addition of it  significantly increases the glass transition temperature (Tg) of the resin, enabling it to maintain stable structure and properties in high-temperature environments. This characteristic makes these resins very advantageous in scenarios that require high-temperature processing or use in high-temperature environments.

4. Improve the chemical resistance of the resin

In many industrial applications, chemical corrosion resistance is an important performance indicator of resin materials. The polyester resin prepared from 2,5-Furandicarboxylic acid (FDCA, CAS No. 3238-40-2) exhibits excellent chemical corrosion resistance due to its unique structure, especially in acidic and alkaline environments. This enables unsaturated resins based on it to be used in the manufacture of chemical resistant containers, pipelines, coatings, and other products, maintaining their superior performance in highly corrosive environments.

5. Improve the environmental friendliness and renewability of resins

Unlike traditional petrochemical raw materials, 2,5-Furandicarboxylic acid (FDCA, CAS No. 3238-40-2) comes from renewable biomass such as cellulose or sugars, resulting in a lower carbon footprint during its preparation process. Using FDCA as the raw material for unsaturated resin not only reduces dependence on non renewable resources, but also lowers carbon emissions during the production process. This is of great significance for the resin industry to achieve sustainable development goals. In addition, due to the bio based properties of it, the resin prepared using this material is more easily degraded by microorganisms in the natural environment after the end of its service life, thereby reducing plastic pollution.

2,5-Furandicarboxylic acid (FDCA, CAS No. 3238-40-2) , as a biobased chemical, has demonstrated its enormous potential in the field of unsaturated resins. It not only improves the mechanical properties, heat resistance, and chemical resistance of the resin, but also has significant environmental advantages. With the increasing global attention to renewable resources and sustainable development, it is expected to become an important raw material in the unsaturated resin industry in the future, driving the resin industry towards a greener and more environmentally friendly direction.
