Trimellitic anhydride is an important organic chemical intermediate, which has a wide range of applications in many industries, the main downstream application areas are:
1. High temperature resistant plasticizer (trioctyl trimellate)
Trioctyl trimeric acid is an environmentally friendly plasticizer prepared by the reaction of trimeric anhydride and octanol. It has the advantages of high temperature resistance, cold resistance, migration resistance and aging resistance, and is suitable for plastic products in high-end fields such as wire and cable, medical supplies and automobiles.
2. Powder coating polyester resin
Trimeric anhydride can be used to produce indoor polyester resin, which is often added to powder coatings for decorative and anti-corrosion applications such as home appliances, bicycles, steel doors and Windows.
3. Insulating paint
Trimeric anhydride is also one of the important raw materials for the manufacture of high temperature resistant insulating paints and insulating laminates. These materials are mainly used in the insulation of motors, as well as in the production of products such as enamelled wire paint and impregnated paint.
4. Epoxy resin curing agent
Trimeric anhydride can also be used as curing agent of epoxy resin, which can effectively improve the performance and stability of epoxy resin.
Trimeric anhydride as a multi-functional organic chemical intermediate, its downstream applications cover high temperature resistant plasticizer, powder coating polyester resin, insulating paint and epoxy resin curing agent. With the development of technology and the change of market demand, the application prospect of trimellitic anhydride is very broad.
