Chemical Properties Of Diisononyl adipate CAS 33703-08-1

  1. Diisodecyl adipate (DINA) is a colorless, transparent liquid with the MF: C24H46O4 and MW: 398.62. It is produced by the esterification of isodecyl alcohol with adipic acid.
  2. DINA is an important aliphatic dicarboxylic acid ester plasticizer, featuring excellent low-temperature performance, volatility resistance, compatibility, and stability.
  3. DINA is a typical cold-resistant plasticizer and also a high-boiling-point solvent. It can be used in applications such as electrical cables, rubber sheets, gloves, shoes, building materials, PVC plasticizing paste, clean film, and cold-resistant PVC products.

Product Application Of Diisononyl adipate CAS 33703-08-1

  1.  Soft PVC products: such as cable compounds (especially cold-resistant cables), films, artificial leather, hoses, gaskets, etc., where adding DINA enhances the low-temperature flexibility and processing flowability of the products.
  2.  Toys and medical device components: It can be selected for certain applications with low migration requirements, replacing some phthalate-based plasticizers (must comply with relevant environmental standards).
  3.  In nitrile rubber and chloroprene rubber products, diisononyl adipate is used as a plasticizer to improve the processing performance of rubber and the low-temperature elasticity of finished products, such as oil-resistant rubber products and seals.
  4.  Diisononyl adipate can be used in small quantities in coatings and adhesives to adjust the flexibility and low-temperature stability of the system, particularly suitable for products used in outdoor or low-temperature environments.
  5.  Diisononyl adipate is also used in plastic sol-gel and ink to enhance the flow properties and low-temperature adaptability of the system.
