Plasticizer
A plasticizer ( UK: plasticiser) is a substance that is added to a material to make it softer and more flexible, to increase its plasticity, to decrease its viscosity, and/or to decrease friction during its handling in manufacture. Plasticizers are commonly added to polymers such as plastics and rubber, either to facilitate the handling of the

Jayflex high-molecular-weight plasticizers provide an optimum balance of properties with outstanding performance and permanence. Adipate plasticizers Jayflex adipate plasticizers can be used as a primary plasticizer but, more typically, are used in blends with general-purpose phthalates to improve low temperature properties.
Superplasticizer
Superplasticizer. Superplasticizers ( SPs ), also known as high range water reducers, are additives used in making high strength concrete. Plasticizers are chemical compounds that enable the production of concrete with approximately 15% less water content. Superplasticizers allow reduction in water content by 30% or more.

Selecting Plasticizers for Adhesives and Sealants
Another method of classifying plasticizers is based on their performance such as: General-purpose plasticizers; High-performance plasticizers ; Specialty plasticizers; Today, phthalates remain the most popular choice because they usually provide the best all-round performance and they are low in cost. However, phthalates are suspected carcinogens.
- How to choose a high-performance ester plasticizer?
- The rubber compounder must evaluate ester plasticizers for compatibility, processability, permanence and performance properties. The study of these properties by the rubber compounder will contribute to the selection of a high-performance ester plasticizer. 1.
- How are ester plasticizers selected?
- Ester plasticizers are selected based upon cost/performance evaluation. The rubber compounder must evaluate ester plasticizers for compatibility, processability, permanence and performance properties. The study of these properties by the rubber compounder will contribute to the selection of a high-performance ester plasticizer.
- What is a plasticizer?
- A plasticizer is a non-volatile substance incorporated in a plastic or elastomer. It changes the thermal and mechanical properties of the material. The expected property changes in a plasticized plastic or elastomer are as follows: Plasticization is classified into two main groups such as internal and external.
- How to make a plastic product more flexible by adding plasticizers?
- The process of making the final plastic product more flexible by adding plasticizers is called plasticization. By adding the right type and amount of plasticizer, you can tweak the polymer properties to get exactly what you need.
- Why does plasticizer efficiency increase in PVC?
- In a specific group of esters sharing a common acid group, the plasticizer efficiency rises when the molecular weight of the plasticizer decreases in PVC. Additionally, enhanced plasticizer efficiency is observed with a more linear alcohol chain. Incorporating a plasticizer into a PVC product extends the lower limit of its useful temperature range.
- Which plasticizer is best?
- The high degree of saturation and potential crystalline character severely limit the choice of plasticizers. After several screening evaluations, a plasticizer that did show some compatibility advantages was a polyester glutarate (G-24,000). This plasticizer has a molecular weight of 5,000.
