Uses: Isononyl alcohol (INA) is mainly used to produce high molecular weight phthalate plasticizers such as diisononyl phthalate (DINP). With the market’s gradual recognition of the safety of DINP, the demand for DIN Chemicalbook P, as an environmentally friendly substitute for low molecular weight phthalate plasticizers such as dioctyl phthalate (DOP), has grown rapidly and is widely used in industrial fields such as automobiles, cables, flooring, and construction.
