Dioctyl Adipate, with the CAS number 123 - 79 - 5, is also known as Bis(2 - ethylhexyl) adipate (DEHA). It is a clear, colorless to slightly yellowish liquid. The molecular formula of Dioctyl Adipate is C₂₂H₄₂O₄, and its molecular weight is approximately 370.57 g/mol. The product has a low volatility, high plasticizing efficiency, and good compatibility with a wide range of polymers. It has a boiling point of around 214 - 215°C at 5 mmHg and a density of about 0.927 g/cm³ at 20°C.
Dioctyl Adipate is primarily used as a plasticizer. In the polymer industry, it is widely applied in the production of polyvinyl chloride (PVC) products. It can improve the flexibility, softness, and workability of PVC, making it suitable for manufacturing various PVC - based items such as wire and cable insulation, automotive interiors, and flexible PVC films. Moreover, it is used in the synthetic rubber industry to enhance the low - temperature flexibility of rubber products. In the cosmetics industry, it can be found in some products like nail polish and hair sprays as a film - forming agent and plasticizer, providing a smooth and flexible finish.
When using Dioctyl Adipate as a plasticizer in PVC production, it should be added during the mixing process. First, ensure that the PVC resin is in a dry and clean state. Then, slowly add the Dioctyl Adipate to the PVC resin while constantly stirring. The recommended proportion of Dioctyl Adipate in PVC formulations usually ranges from 10% to 30%, depending on the specific requirements of the final product. For example, if a more flexible product is needed, a higher proportion can be used. In the synthetic rubber industry, it can be incorporated into the rubber compound during the mixing stage on a rubber mixer. The amount added also needs to be adjusted according to the type of rubber and the desired properties of the final rubber product.
Case 1: PVC Wire and Cable Insulation
A cable manufacturing company used Dioctyl Adipate in its PVC insulation formulation. By adding 20% Dioctyl Adipate to the PVC resin, the insulation layer became more flexible, which was beneficial for bending and installation of the cables. The low - temperature performance of the cables was also improved, ensuring that they could still function properly in cold environments. As a result, the company received positive feedback from customers, and the demand for their cables increased.
Case 2: Automotive Interior Parts
An automotive parts manufacturer incorporated Dioctyl Adipate into the PVC used for dashboard covers. With a 15% addition of Dioctyl Adipate, the dashboard covers had a better soft - touch feeling, improving the overall comfort in the vehicle interior. The plasticizer also enhanced the durability of the dashboard covers, making them more resistant to cracking and aging. This led to a reduction in product returns and an improvement in the brand's reputation in the automotive market.
