Trimellitic anhydride (TMA) is an important chemical intermediate and an important raw material for polyester resin, polyimide resin, PVC heat-resistant plasticizer, epoxy resin curing agent, dye capacitor impregnating oil and adhesives and other products. However, TMA is respiratory sensitizing, and can cause severe and permanent damage to lung function if exposed for prolonged periods of time and without intervention. In order to comply with environmental protection requirements, the application of non-TMA resins will become a future trend.
HH2781 is a completely TMA free hybrid polyester resin.
