Plasticizers - Chemical Economics Handbook (CEH) | S&P Global - IHS Markit
Published May 2025. Flexible polyvinyl chloride (PVC) accounts for 80–90% of global plasticizer consumption. Flexible PVC (and thus plasticizers) is found in the following applications: construction (flooring, wall coverings), electrical (wire and cable jacketing), consumer goods (toys, footwear, etc.), packaging, transportation (inside and outside of vehicles), furnishings, and medical uses
Effect of Functional Polycarboxylic Acid Superplasticizers on
Modern engineering practices require that polycarboxylic acid high-performance superplasticizers have good adaptability to various environments and materials, which indicates the importance of
Effect of Naphthalene-Based Superplasticizer and Polycarboxylic
In order to study what the effect of superplasticizers on the setting time, fluidity and compressive strength of calcium sulfoaluminate cement (CSA) a naphthalene-based superplasticizer (BNS) and
Comparative study of Conplast SP 430 and Polycarboxylic Ether
So, the superplasticizers are used to improve the workability. In this study two different plasticizers Conplast SP 430 and Polycarboxylic Ether (PCE) are used and their performance on the...
Plasticizer
Plasticizers used in PVC and other plastics are often based on esters of polycarboxylic acids with linear or branched aliphatic alcohols of moderate chain length. These compounds are selected on the basis of many critieria including low toxicity, compatibility with the host material, nonvolatility, and expense.
- What is a polycarboxylate superplasticizer (PCE)?
- Polycarboxylate superplasticizers (PCEs) prepared by traditional free radical initiation methods need to use chemicals as initiators, which are environmentally unfriendly. In contrast, photoinitiat...
- Does polycarboxylate superplasticizer alter dispersion and water-reducing effects?
- Polycarboxylate superplasticizer, synthesized using different methods, may alter dispersion and water-reducing effects. The synthesis of PCE involves creating a novel macromolecular monomer with a controllable molecular mass, adjustable lipophilic, and hydrophilic moieties, as outlined in this study.
- How are amide-structural polycarboxylate superplasticizers produced?
- In another study by Liu et al. , amide-structural polycarboxylate superplasticizers (amide-PCEs) were produced by amidation reaction between polyacrylic acid (PAA) and amino-terminated methoxy polyethylene glycol (amino-PEG) at 130–150°C.
- What is polycarboxylic ether superplasticizer?
- Introduction Generally, polycarboxylic ether superplasticizer (PCEs) have excellent properties of high water reduction and high slump retention capacity, and they are widely used in engineering , , , . In the synthesis of PCEs, the types of macromonomers are extremely important.
- What is the molecular structure of modified polycarboxylate superplasticizer (PCE-P)?
- The FTIR results revealed that the molecular structure of the modified polycarboxylate superplasticizer (PCE-P) comprised sulfonic acid, carboxylic acid, and polyepoxyethane vinyl groups, exhibiting a comb-like molecular structure.
- Does polycarboxylate superplasticizer (PCE-P) affect the dispersibility of cement paste?
- polycarboxylate superplasticizer (PCE-P). The study investigated the effects of different PCE types potential of cement paste. PCE-P, synthe- rate in cement to PCE synthesized at high temperatures. PCE-P exhibited an increased slump but had in surface tension, indicating a good dispersibility.
