Description

Di(2-Ethylhexyl) Tetrahydrophthalate is a high-performance, low-volatility plasticizer derived from tetrahydrophthalic anhydride. This compound is valued for its excellent compatibility with a wide range of polymers, providing enhanced flexibility and durability to finished products. It is primarily sought after by manufacturers in the plastics, coatings, and specialty chemical industries for formulating flexible PVC, adhesives, and sealants.

Application

• Primary plasticizer for flexible Polyvinyl Chloride (PVC) compounds in wire & cable insulation, flooring, and synthetic leather.
• Key component in the formulation of specialty adhesives and sealants, improving their workability and long-term elasticity.
• Used as a processing aid and secondary plasticizer in various polymer blends and elastomers to modify physical properties.
• Employed in the production of coil coatings and industrial paints to enhance film flexibility and adhesion.
• Functional fluid or additive in lubricants and hydraulic fluids for specific industrial applications.
• Plasticizer for printing inks and color concentrates, aiding in pigment dispersion and substrate adhesion.
