DINP, a plasticizer obtained from the reaction of phthalic anhydride with isononyl alcohol; has good compatibility with PVC and has a very low migration rate at high concentrations. It provides excellent rheological properties to the product in plastisol applications. Due to its low volatility, it helps to improve process conditions. It has excellent resistance to outdoor conditions and water, and therefore is suitable for film production in the construction sector. Due to its low viscosity and very good viscosity stability, it is ideal for plastisol applications such as spray coating, dipping, and molding.
