DINP is produced by esterifying Isononanol Phthalic Anhydride. DINP's plasticizing characteristic is similar to that of DEHP. However, DINP's low volatility is advantageous for certain applications. DINP is a general plasticizer. Compared to DEHP, DINP's plasticizing efficiency, migration and water extraction rate are lower, while its gelation temperature and electric resistivity are mildly higher. DINP's low volatility not only extends the life of a product, but also reduces evaporation during processing.
