  • What percentage of DINP is used in PVC?
  • Specifically, approximately 95 percent of DINP produced is used in PVC as a plasticiser. More than half of the remaining 5 percent is used in the production of polymers other than PVC (e.g. rubber). The remaining DINP is used in non-polymer applications including anti-corrosion paints, anti-fouling paints, lacquers, inks, adhesives and sealants.
  • How does DINP affect the environment?
  • Environmental Impact: DINP is not considered persistent or bioaccumulative, and it undergoes degradation in the environment. Nevertheless, measures should be taken to prevent its release during production, use, and disposal to minimize potential environmental effects.
  • How has DINP been regulated?
  • Regulatory Assessment: DINP has undergone extensive regulatory scrutiny to assess its safety. Regulatory bodies, such as the U.S. Environmental Protection Agency (EPA) and the European Chemicals Agency (ECHA), have conducted evaluations and established guidelines to limit exposure levels.
  • What are the properties of DINP Plastisol?
  • The main properties of DINP are low volatility and density. DINP displays good resistance to aging as well as easy plastisol coating, spraying and dipping. Further, it is also compatible with secondary plasti-cizers. Low volatility and density enables reduced process emissions and improved working conditions.
  • Is DINP soluble in organic solvents?
  • It is soluble in most organic solvents. DINP is primarily used as a PVC plasticizer. As compared to DOP, the low volatility and better endurability of DINP significantly reduces the fume emissions during the processing procedure and improves its permanence in the final product.
  • How is DINP produced?
  • DINP is produced by esterification of phthalic anhydride with isononyl alcohol (= isononanol) in a closed system. The reaction rate is accelerated by elevated temperatures (140-250 °C) and a catalyst.
