Plasticizer - an overview | ScienceDirect Topics
Plasticizers are low molecular weight substances added to a polymer solution to promote its plasticity and flexibility. Therefore, the plasticizers make the polymer solution more suitable for the application of film coating. There should be chemical similarities between the polymers and its plasticizers.
Plasticizers – Benefits, Trends, Health, and Environmental Issues
Plasticizers soften the PVC to make it flexible and bendable. This opens up a huge range of possibilities for new applications. One of the main benefits of plasticizers is the durability they confer onto PVC applications, which can ensure high performances for up to 50 years.
Plasticizer
It was commonly thought that plasticizers work by embedding themselves between the chains of polymers, spacing them apart (increasing the "free volume"), [3] [4] or swelling them and thus significantly lowering the glass transition temperature for the plastic and making it softer.
Plastic Additives: Polymer Stabilizers, Plasticizers and
Plasticizers can increase the flexibility, extensibility, and plasticity of plastics because of their ability to weaken the van der Waals forces between polymer molecules, thereby increasing the mobility of polymer molecular chains and reducing the crystallinity of polymer molecular chains.

- Does Russia have a decline in demand for plastic products?
- According to data of the Russian analyst agency Romir, the demand for plastic products in Russia has declined by 10-40 percent, depending on the product, compared with 2021. Russia's largest materials supplier, Sibur, agrees. "There is currently a decline in demand that varies across the industry," a Sibur executive said in an exclusive interview.
- Will Russia's plastic industry be affected by a suspension of imports?
- According to the Russian Union of Plastic Processors — a public association for producers of finished plastic products — 95 percent of the industry's equipment is imported, much from Western countries. Analysts believe the suspension of imports may lead to catastrophic effects in the industry.
- How does plasticizer affect the plasticity of polymers?
- the plasticity of polymers. It is shown that the hardness, modulus, softening temperature and embrittlement temperature of polymers decrease, elongation, flexibility and flexibility increase. Plasticizer is a low molecular chemical or polymer, which can increase the plasticity of the polymer,it is
- What is the demand for Russian polymers?
- Sibur and other leading Russian analysts project that the current level of demand for Russian polymers is generally high: 700,000-800,000 tonnes per year, about 300,000 tonnes of which are polyethylene and polypropylene — polymers currently produced domestically. Sibur is also opening new production with the aim of replacing imported materials.
- How many polymers can Russia produce a year?
- The total potential for these products, according to initial estimates, is about 50,000 tonnes per year. At present, the overall capacities for the production of base polymers in Russia are estimated at 8.3 million tonnes, while the volume of processing is 5 million tonnes, of which about 25 percent account for imported products.
- What happened to Russia's largest plastics supplier?
- Russia’s largest materials supplier, Sibur, has seen the same drop. The Russian plastics industry is facing the deepest crisis in its modern history, as the military conflict with Ukraine has led to an almost complete suspension of imports of key raw materials, finished products and crucial technology.
