Trimellitic Anhydride (TMA), identified by its CAS number 552-30-7, is a chemical intermediate of significant importance across multiple industrial sectors. For those in procurement and R&D, understanding its core properties, applications, and how to reliably buy it is essential. This guide, offered from the perspective of a dedicated manufacturer, aims to clarify the value and accessibility of high-purity TMA.

Chemically, Trimellitic Anhydride is a derivative of trimellitic acid, featuring a reactive anhydride group. This structural characteristic makes it an excellent precursor for synthesizing a range of valuable compounds. Its typical appearance is a white flake, and it boasts high purity levels, often exceeding 97.0% total anhydride content. These specifications are critical for applications where consistent chemical reactions and predictable material properties are required. The molecular weight is approximately 192.13 g/mol, and its melting point is typically around 164-166 °C.

The applications of TMA are diverse and impactful. It is widely used in the production of plasticizers, particularly those designed for high-temperature resistance, which are crucial for the automotive and electrical industries. Furthermore, TMA is a key monomer for creating high-performance polymers like polyimides and polyesters. These polymers are valued for their exceptional thermal stability, mechanical strength, and dielectric properties, finding use in aerospace, electronics, and specialized coatings. For any R&D scientist looking to advance material science, sourcing premium TMA is a logical step.

As a curing agent, Trimellitic Anhydride plays a vital role in thermosetting resins, especially epoxy systems. It promotes crosslinking, leading to cured resins with enhanced hardness, chemical resistance, and thermal stability. This makes TMA an ideal choice for industrial coatings, adhesives, and composite materials that must perform under challenging conditions. The ability to achieve superior performance attributes hinges on the quality of the curing agent.
