Description

1,2,4-Benzenetricarboxylic Acid Tris[2-(2-Butoxyethoxy)Ethyl] Ester is a high-purity, non-phthalate plasticizer and specialty ester derived from trimellitic acid. This compound matters for formulators seeking a high-performance, low-volatility additive that imparts excellent flexibility and durability to polymer systems. It is primarily needed by manufacturers in the plastics, coatings, and adhesives industries who require enhanced processing characteristics and long-term product stability.

Application

• Primary plasticizer for PVC, vinyl resins, and other polymers requiring low migration and high permanence.
• Key component in high-temperature wire and cable insulation formulations.
• Functional additive in specialty coatings and adhesives to improve film flexibility and adhesion.
• Plasticizer for synthetic leather and coated fabrics demanding excellent cold flexibility.
• Processing aid in elastomer and sealant compounds to enhance workability.
• Solvent and carrier in specialty ink and dye applications.
• Additive for gaskets and automotive interior components.
