Bioplasticizer - an overview | ScienceDirect Topics
24.14 Other Plasticizers. This category includes a variety of different plasticizers including polyol esters, nonepoxy bioplasticizers, and miscellaneous plasticizers. In 2005, Danisco introduced their new bioplasticizer, Soft-n-Safe (SNS). This plasticizer is based on castor oil, where the oil is hydrogenated, then transesterified, and
Databook of Plasticizers - 2nd Edition
Description. Databook of Plasticizers, Second Edition, contains data on the most important plasticizers in use today, including over 375 generic and commercial plasticizers. The data comes from a range of sources beyond plasticizers' manufacturers, allowing for a detailed comparison of properties between different plasticizers.

Types And Differences Of Common PVC Plasticizers
Dipentaerythritol ester has low volatility, good extraction resistance, difficult thermal decomposition and oxidation, and good electrical insulation performance. It is an excellent heat-resistant plasticizer. It is suitable for high-temperature wire insulation formula, but the price is expensive.

125°C wires. As a polyester plasticizer, a polyester having a molecular weight of from 2000 to 8000 is practically used. However, this is also limited to a heat resistance level for 105°C wires. Further, in a certain limited field, a dipentaerythritol ester is
- What are the advantages of dipentaerythritol ester?
- Dipentaerythritol ester has low volatility, good extraction resistance, difficult to thermal decomposition and oxidation, electrical insulation and good performance, is excellent heat plasticized Liu, suitable for high temperature wire insulation formulations, but the price is expensive.
- What are the two types of dipentaerythritol ester?
- (1) Dipentaerythritol ester (referred to as PCB) Dipentaerythritol ester can be divided into ether type and ester type. These two types of double-penta-tetramethyl ester are light yellow viscous oily liquid. Soluble in organic solvents, insoluble in water. The company is located in:
- Can pentaerythritol esters be used in aircraft engine lubricants?
- The novel 5 mm 2 /s pentaerythritol ester containing diacid pentaerythritol complex esters exhibits improved viscosity-temperature performance, high-temperature oxidation resistance, and better tribological properties. Therefore, the novel pentaerythritol esters show potential for application in 5 mm 2 /s EE aircraft engine lubricants. 1.
- Do pentaerythritol esters improve oxidation stability?
- Studies on the relationship between the properties and structure of conventional pentaerythritol esters indicate that changing the fatty acid chain length or using dipentaerythritol esters does not simultaneously improve the oxidation stability and extreme pressure and anti-wear performance of pentaerythritol esters.
- What is dipentaerythritol used for?
- Dipentaerythritol (DPE) is an attractive raw material used for the production of polyesters, polyethers, polyurethanes, alkyd resins, photosensitive resin film. DPE is also employed in a wide range synthesis of specialty chemicals such as lubricants, coatings, adhesives, plasticizers and cosmetics.
- How many ester groups does a diacid pentaerythritol complex have?
- This can be attributed to the fact that diacid pentaerythritol complex esters have 8 or 16 ester groups, more than the ester group numbers of pentaerythritol ester (PE-nC5) and dipentaerythritol ester (DPE-nC5) (Fig. 18).
