Dihexyl phthalate

Dihexyl phthalate (CAS 84-75-3 ) is a phthalate-based plasticizer used to impart flexibility and processability to polymer systems. Di-n-hexyl phthalate is a commercially recognized designation buyers may encounter across supplier documentation.

In PVC compounding, it functions as a primary plasticizer to produce flexible films, tubing, and profiles where moderate volatility and good low-temperature performance are required for the final product.

Automotive sealants and underbody coatings incorporate it to maintain flexibility across a broad service temperature range. Adhesive and elastomer formulations use it to control hardness and improve substrate adhesion.

In industrial bonding applications, this chemical ensures durability. Coatings manufacturers also use it as a processing aid to adjust viscosity and film-forming characteristics in various solvent-borne systems.

This substance is supplied as a clear to pale yellow liquid in standard bulk and drummed packaging. Technical grade is the primary commercial form available from industrial chemical suppliers today.

Buyers should confirm purity specifications and compliance documentation directly with the supplier. This is particularly important where end-use applications involve regulated polymer contact materials or specific safety standards.
