Rheological properties of dioctyl adipate-modified asphalt
The rheological characteristics analysis shows that DOA could increase the viscous components in asphalt binder. However, with the increase of plasticizer content to 3.0%, the creep rate increased by 35% and the creep stiffness decreased by 39% at 24°C. The low temperature performance of DOA modified asphalt binder was improved by 30%.
Dioctyl Adipate (DOA) - Chemical Supplier Distributor Chemceed
Application. Dioctyl Adipate (DOA) is a colorless, odorless, transparent oily liquid that is most often used as a PVC plasticizer. DOA is compatible with a wide range of materials such as nitrocellulose, ethyl cellulose, most synthetic rubbers, cellulose acetate butyrate, PVC, chloroethylene polymer, and cellulose nitrate.
Dioctyl adipate
Dioctyl adipate ( DOA) is an organic compound with the formula (CH 2 CH 2 CO 2 C 8 H 17) 2. It is a colorless oily liquid. As well as related diesters derived from 2-ethylhexanol, decanol, isodecanol, etc., it is used as a plasticizer. [2] [3] DEHA is sometimes incorrectly called dioctyl adipate. Toxicity [ edit]

DEHA is also known as dioctyl adipate (DOA), hexanedioic acid, and bis(2-ethylhexyl) hexanedioate in some documents cited below. The vapor pressure for DEHA indicates that in the atmosphere it may exist in both the gas and particle phases. It will be removed from the air via dry and wet deposition or via degradation
- What are adipate plasticizers?
- Adipate plasticizers contain two carbonyl groups (C O) in a linear configuration at the center and alkyl chains (R) on both sides. In this study, we used five adipate plasticizers with different numbers of carbon atoms in the alkyl chain, including DMA, DEA, DBA, DOA, and DDA, to synthesize adipate PVC gel (Fig. S1).
- Which Adipate Plasticizer is better at 65 °C?
- At 65 °C, the output voltages of DMA1, DEA1, DBA2, and DDA3 PVC gel-based TENGs decreased to 11 %, 9 %, 82 %, and 46 %, respectively. In contrast, DOA5 showed excellent output stability irrespective of temperature. The change in the performance of the TENG based on other ratios of adipate plasticizers is discussed in Note S3.
- Are dibutyl adipate plasticizers effective?
- It has been reported that PVC gels containing dibutyl adipate (DBA) plasticizers exhibit improved output performance and stretchability and operate stably for a long time at room temperature.
- Why is DOA a good material?
- DOA maintains the flexibility and ductility of the material at low temperatures, significantly lowering the glass transition temperature of the polymer and making it suitable for plastics used in cold environments, such as frozen food packaging film and outdoor plumbing .
- Does adipate PVC gel-based TENG withstand high humidity conditions?
- We also conducted tests to evaluate the stability of adipate PVC gel-based TENG when exposed to high humidity conditions (Fig. S18). Each adipate PVC gel was immersed in water for 10 days, and the resulting change in plasticizer weight was measured. DMA and DEA gels exhibited weight losses of approximately 81 % and 36 %, respectively.
- What are the advantages of DOA lubrication?
- DOA can improve the light and heat resistance of the products and reduce the degradation caused by UV rays or high temperature, which is suitable for outdoor films and coated fabrics. Artificial leather and plates: Improvement of low-temperature flexibility, enhancement of surface lubrication and water resistance.
