Di Iso Nonyl Phthalate

Di iso nonyl phthalate (DINP) is a clear, colourless liquid with a slight odour. It is miscible with other organic solvents but insoluble in water. It is preferred over other products due to its low toxicity, which makes it suitable for use in a wider range of applications.

It has several advantages in that it provides the desired changes to physical and mechanical properties without causing changes to the chemical structure of the polymer; it extends the life of plastic goods and provides electrical resistance; it allows a lower viscosity PVC paste to be produced and, owing to its lower density, it produces volume advantages. Its excellent resistance to cold and water give it a distinct advantage over alternative products for the housing and construction markets.

Applications of Di Iso Nonyl Phthalate

Di iso nonyl phthalate is used as a softener in PVC paste and pulp mixtures. It is also used in polymers for adhesives, vinyl flooring, laminators, resins, surfactants, screen printing inks as well as in non-polymer applications such as adhesives, paints and T-shirt printing inks.

DINP is used in a wide range of industrial products such as electrical cables, PVC sheeting, coated fabrics, waterproofing materials used in construction, vinyl floorings and automotive parts. It is also used in consumer products such as synthetic leather, shower mats, children’s toys, school supplies such as flexible rulers, erasers and pencil cases, as well as in baby products such as changing mats and dummies.

Storage and Handling

Di iso nonyl phthalate should be stored in a tightly-closed container in a cool, dry, well-ventilated place away from sources of ignition and strong oxidizers.

The product should be handled in accordance with good industry safety and hygiene practices. Engineering controls including adequate ventilation should be implemented. Personal protective equipment deemed suitable by appropriate risk assessments should be worn, which may include safety glasses and impervious gloves to prevent eye and skin contact.
