China and Germany are the leading exporters of Trioctyl trimellitate (CAS 3319-31-1), accounting for the largest shares of global shipments in recent years, while the United States, South Korea, and India represent the top importing markets. Trioctyl trimellitate prices have remained relatively stable amid steady demand from PVC stabilizer applications. Export volumes from China increased modestly in 2023–2024, while German exports held steady, reflecting continued dominance by these two suppliers amid limited new entrants.
Trioctyl trimellitate is a colorless to pale yellow, viscous liquid at room temperature with low volatility and no characteristic odor. It is an ester of trimellitic acid (1,2,4-benzenetricarboxylic acid) and 2-ethylhexanol (commonly referred to as “octyl” in commercial nomenclature), classified as a non-phthalate plasticizer. It is primarily used as a high-molecular-weight, heat- and light-stable plasticizer for polyvinyl chloride (PVC) and other thermoplastics. Typical application areas include wire and cable insulation, automotive interior parts, flooring, and synthetic leather—where enhanced thermal stability and low volatility are required. It is also employed in specialty polymer formulations demanding improved extraction resistance and long-term performance.
TRIOCTYL TRIMELLITATE is a plasticizer that was evaluated for endocrine disrupting activities through estrogen receptor alpha binding assay.
