Product type
Diisononyl Phthalate (DINP) is a high-performance plasticizer commonly used to enhance the flexibility and durability of various plastic products. It is synthesized from phthalic anhydride and isononanol, resulting in a clear, colorless liquid that is non-toxic and environmentally friendly. DINP is primarily utilized in the production of polyvinyl chloride (PVC) and other polymers, making it an essential additive in the manufacturing of flexible materials.
