Introduction:
DINP (Di-lsononyl Phthalate) is produced by esterifying Isononanol and Phthalic Anhydride. Its plasticizing efficiency, migration and water extraction rate are lower and its gelation temperature and electric resistivity are slightly higher. DINP’s low volatility not only prolongs the service life of the product but also reduces the evaporation during the process.
Application:
DINP’s volatilization weightlessness is smaller than DOP. Intrinsic viscosity is similar to DOP. You will get a more high viscosity value if use DINP alone.
DINP is suitable for the plastic production, proving stable viscosity and no problems exist during disperse foaming. The melting temperature is low. As the PVC coating, DINP has the lowest viscosity and the change in viscosity quite small.
Mainly used to PVC, and also widely used to toys’ film, wire and cable since DINP has good water proofing, extraction resistance, electric insulating property and low-poisonousness.
Industry thin-film, waterproof cloth, layer sheet, ground covering, wallpaper, cable batch, special type fibre, artificial leather binder, coating, solvent, packaging film, tube stock and sectional materials.
