QUICK LINKS

Diisopropyl phthalate functions by increasing the flexibility and durability of various polymers and resins, allowing for the production of more malleable and resilient materials. Diisopropyl phthalate interacts at the molecular level by forming strong, non-covalent bonds with the polymer chains, reducing intermolecular forces and increasing the free volume within the material. This results in improved flow properties and reduced brittleness, enhancing the performance of the polymer. Diisopropyl phthalate′s mode of action involves its ability to effectively disperse and separate polymer chains. Diisopropyl phthalate′s function as a plasticizer developments various products, as it enables the production of flexible and durable materials with enhanced mechanical properties.
