Plasticizer - an overview | ScienceDirect Topics
Introduction of plasticizers into the biopolymer reduces the melt viscosity of the polymer and lowers the temperature, pressure, and shear rate required to melt-form the polymer. Plasticizers also prevent heat build-up and consequent discoloration and molecular weight decrease during processing steps, such as production and packaging.
Plasticizer
In the concrete technology, plasticizers and superplasticizers are also called high range water reducers. When added to concrete mixtures, they confer a number of properties including improved workability and strength. The strength of concrete is inversely proportional to the amount of water added, i.e., the water-cement (w/c) ratio.
A Strategy for Nonmigrating Highly Plasticized PVC - Nature
With higher DOP-O-CP52 levels in PVC, CP52 in DOP-O-CP52 will form microclusters owing to their lower compatibility with PVC, to retard the movement of DOP-O-CP52 in PVC, resulting in a decline in...

High purity non‐stain plasticizers for floor and wall
Resistance to stains is imparted to such surfaces through a four part mechanism which relates directly to plasticizer composition. Benzoate esters of 2,2,4‐trimethyl‐1, 3‐pentanediol have traditionally been used as stain resistant plasticizers, but are available commercially only as complex mixtures with reaction by‐products.
- How do Plasticizers improve polymer material flexibility & durability?
- Plasticizers improve polymer material flexibility and durability by lowering glass transition and cold flex temperatures. While many different classes of plasticizers have been synthesized and used...
- Does a plasticizer lower the Tg of PVC?
- Since the purpose of a plasticizer is to increase the chain mobility, Tg has been demonstrated to be a good indicator of the polymer structure and eficacy. We showed that DEHP lowers the Tg of PVC by almost 100 K, from between 350 and 400 K to between 250 and 300 K. DBS and DHS were the only other plasticizers able to lower the Tg Figure 3.
- Which plasticizer possesses a favorable plasticization effect on PVC?
- Among, Yao et al. synthesized an environmental-friendly plasticizer CEP originated from cardanol by click chemistry, the results showed that it possessed favorable plasticization effect and stabilization effect on PVC. Zhu et al. designed and synthesized a new type of VA-based plasticizer (VA4-Cn).
- Which plasticizer is used to make polyvinyl chloride (PVC) films?
- Subsequently, ricinoleate plasticizer, commercially available dioctyl phthalate (DOP), and bis (2-ethylhexyl) adipate (DOA) were added to prepare polyvinyl chloride (PVC) films for performance comparison.
- What is the mechanism of plasticization between pure PVC and PVC films?
- The potential mechanism of pure PVC and the PVC films plasticized with A-ODL were displayed in Fig. 8. According to reports in the literature, there were currently three popular plasticizing mechanisms : free volume theory, lubrication theory and gel theory. The mechanism between A-ODL and PVC could be explained by these three theories.
- What are the characteristics of plasticizers market?
- ed MaterialsAs mentioned above, plasticizers market is directly linked to the polymer market and partic-u arly to PVC. Therefore, properties of plasticized products presented in the following are typical of PVC pplications:Abrasion ASTM D5963). It is used in appli-cations where the material undergoes friction continuously, like
