Plasticizers | SpringerLink
The plasticizers with the largest market in this chemical group are bis(2-ethylhexyl) adipate (DEHA also called DOA) and dibutyl adipate (DBA). Pastes made with adipates for plastisol applications have low viscosity increase during storage, enabling manufacturers to produce high-volume batches with low frequency, maintaining a stable operation.
Plasticizer for poly(vinyl chloride) from cardanol as a
This high purity esterification was obtained using, 7 g of cardanol and 6.57 ml (7.09 mol, 3 equivalents) of acetic anhydride, diluted in 5 ml di pyridine, and held for 2 h at 50 °C. Then, the solution was washed with HCl aqueous solution, dried, and filtered.

polyvinyl chloride (PVC), strength, flexibility and durability. The purity requirements for commercial plasticizers are very high; phthalate esters are usually colorless and are mostly odorless. Although the various kinds of plasticizers in use today have some structural similarity, each one is different in the way it performs.

Plasticizers and lubricants are used with some types of binders. Plasticizers increase the flexibility of the ceramic mix. Lubricants lower frictional forces between particles and reduce wear on equipment. Water is the most commonly used liquid in plastic and slurry processing. Organic liquids such as alcohols may also be used in some cases.

- What will China's plasticizer industry look like in the future?
- This will be the major task for Chinese plasticizer and soft PVC industries in the future. Phthalate plasticizers will still be the dominant type and production volume globally in the future, but those of long-chain (C 9 –C 10) alcohol-based esters and non-phthalate plasticizers will increase largely.
- What should be done to improve plasticizer industry?
- More efforts should be devoted to R&D to develop new materials and products. The technological level and product competitiveness need to be improved to expand the international market shares and enable adequate space for our plasticizer industry.
- How can plasticizer industry expand international market shares?
- The technological level and product competitiveness need to be improved to expand the international market shares and enable adequate space for our plasticizer industry. In 2016, Zhiyu Zhao from Qingdao University of Science and Technology carried out the “Investigations of Production of Environmentally Friendly DEHCH” .
- Why is dehch a good plasticizer?
- DEHCH is an exceptional low-toxicity, environmentally friendly plasticizer. China is the major producer of DOP. Production of DEHCH via hydrogenation of DOP is of important significance to the upgrading of plasticizers in China. High-performance catalyst is a key factor for the hydrogenation of DOP.
- Why are plasticizers so expensive?
- The costs of these plasticizers such as citrates are rather high due to the use of expensive catalysts, forcing the users to choose low-cost, traditional options. Accelerated elimination of toxic plasticizers and the invention of non-toxic candidates have become an inevitable trend.
- Which country produces the most plasticizer in Asia?
- Currently, China has the largest plasticizer production and consumption in Asia, with a capacity of 2.2 million tons, an actual volume of 1.3 million tons, and an apparent consumption of 1.7 million tons. Although some plasticizer products are in a leading position globally, in general obvious gaps still exist compared with developed countries.
