Rheological properties of dioctyl adipate-modified
Download full-text PDF Abstract and Figures By referring to the successful application of a cold-resistant plasticizer in the plastic industry, dioctyl adipate (DOA) plasticizer was...
Rheological properties of dioctyl adipate-modified asphalt
The residual creep rate ratio of the plasticizer-modified asphalt binder was more than 15% higher than base asphalt at the same temperature and softening point increment was 22.5% lower than base asphalt which means that the anti-aging performance was improved.
Ecotoxicity of the Adipate Plasticizers: Influence of the
The glass transition temperatures of PVC composites plasticized with alkyl butoxyethyl adipates were determined using DSC analysis. The ecological safety of esters was assessed by the phytotesting method. Samples of adipates were tested for fungal resistance, and the process of their biodegradation in soil was also studied.
How to improve the cold resistance of PVC sealing strips?
Improving the cold resistance of PVC soft products can generally be obtained by increasing the amount of cold-resistant plasticizer. DOA (dioctyl adipate), DIDA (dodecyl adipate),...
Types And Differences Of Common PVC Plasticizers
It is an excellent heat-resistant plasticizer. It is suitable for high-temperature wire insulation formula, but the price is expensive. While ethylene glycol ester has good cold resistance, it has deep color and high volatility. (1) Dipentaerythritol esters (PCB for short) dipentaerythritol esters can be divided into ether type and ester type.
- How cold resistant is PVC plasticizer?
- The PVC plasticized by these plasticizers exhibits outstanding cold resistance. Nowadays, the most commonly used cold-resistant plasticizer, bis (2-ethylhexyl)adipate (DOA), not only has the poor migration resistance so that it can only be used as auxiliary plasticizer, but also causes huge pollution to the environment, especially water.
- What is a good solvent for Dioctyl adipate?
- DOA is a non-polar molecule, meaning it tends to dissolve well in other non-polar solvents. Some examples of good solvents for DOA include aliphatic hydrocarbons such as hexane and heptane. The structure of dioctyl adipate is as follows: This structure imparts several key properties to dioctyl adipate (DOA):
- Can a cold-resistant plasticizer be used as an auxiliary plasticizer?
- Currently, because of the poor migration resistance, the most commonly commercial cold-resistant plasticizer DOA, can only be used as an auxiliary plasticizer with no more than 20 wt% in PVC. More seriously, the precipitation of DOA in the PVC matrix is likely to cause great pollution to the environment, especially water.
- What is the structure of Dioctyl adipate?
- The structure of dioctyl adipate is as follows: This structure imparts several key properties to dioctyl adipate (DOA): ● (1) Low-temperature flexibility: DOA maintains flexibility even at low temperatures, ensuring optimal performance in cold environments.
- Is Dioctyl adipate polar or nonpolar?
- Dioctyl adipate (DOA) is an organic compound belonging to the ester class, with a chemical formula of (CH2CH2CO2C8H17)2. Its molecular structure consists of two octyl groups (C8H17) connected by a central adipate group (CH2CH2CO2). DOA is a non-polar molecule, meaning it tends to dissolve well in other non-polar solvents.
- Is Dioctyl adipate toxic?
- Dioctyl Adipate has low toxicity, with an oral LD50 of 3000 to 6000 mg/kg in rats, and minimal irritation to skin and eyes. While DOA is considered to be non-toxic, it is important to handle it with care to avoid potential hazards.
