Superplasticizers or high range water reducers or dispersants are chemical admixtures that can be added to concrete mixtures to improve workability. Adding 1-2% superplasticizer per unit weight of cement is usually sufficient
PVC without plasticizer is rigid and hard, used in applications where stiffness is needed, such as pipes and window frames. PVC with plasticizer is flexible and soft, used in products like inflatable toys and medical tubing. The plasticizer helps increase the flexibility and workability of the PVC material.

Distyrene Plasticizer Xylene
A plasticizer is defined as a group of substances that help to impart flexibility, viscosity, and softness into common plastics. Currently, these modifiers are most popular with corporations like the U.S. Plastic Corporation.
Hard gelatin capsules have a body and a cap. They are cylindrical in shape and are sealed after they have been filled with medications. Soft gelatin capsules are just one single unit after the two halves have been sealed. They also consist of liquids and are prepared from plasticizer and gelatin.
Ethyl acetate is a solvent that can help increase the flexibility and durability of certain plastics. It is used as a plasticizer to improve the material's ability to bend without breaking, making the plastic more suitable for various applications. Additionally, ethyl acetate is relatively easy to work with and is cost-effective compared to other plasticizer options.
Dibutyl Phathalate Xylene
difference between as on and as at
An example of the most common, general purpose plasticizer is DOP, dioctyl phthalate, also known as DEHP, or diethylhexyl phthalate. This plasticizer is most commonly seen in PVC, but can be found in other polymer systems as well. General purpose plasticizers primarily impart flexibility to a polymer and improve its workability. An example of a specialty plasticizer would be dipropylene glycol dibenzoate. This plasticizer is often found in PVC as well as many other polymer systems including acrylates and urethanes. Specialty plasticizers also impart flexibility but have the added benefit of special properties, such as improving gloss, imparting better low temperature flexibility, faster fusion, etc. Plasticizers are typically esters of some type. Some examples of general classes of plasticizers include: phthalates benzoates adipates citrates trimellitates The "original" plasticizer was camphor, which was phased out during the early 20th century with the discovery of phthalates.
