Diisononyl Adipate(DINA) is a transparent liquid with high stability and soluble to most organic solvents. DINA is of intermiscibility with polyvinyl chloride (PVC). It is a secondary plasticizing agent and a typical cold-resistant plasticizing agent. Compared to DOA, DINA is of equivalent cold-resistance and pliability, less smoke emission during processing, very small volatilization loss, and meets the environmental-protection requirements.
