Plasticizer
Plasticizers can be added to wallboard stucco mixtures to improve workability. In order to reduce the energy consumed drying wallboard, less water is added, which makes the gypsum mixture very unworkable and difficult to mix, necessitating the use of plasticizers, water reducers, or dispersants.
What Plasticizers Do & How They Affect Properties | Osborne
Plasticizers act like a lubricant among polymer chains to reduce rigidity. Without them, synthetic polymer materials would be too brittle and rigid for any practical purpose. For example, plasticizers give rubber its extensibility. Approximately 90% of all plasticizers are used in polyvinyl chloride, or PVC.
What Are Plasticizers? | Plasticizers in Plastic Manufacturing
Plasticizers work in a similar way, and without them, the material would be hard, rigid, and more difficult to shape. Four Families of Plasticizers Over 30,000 substances have been tested for use as a polymer plasticizer, though today, only about 50 are available for use. Of these, they are divided into four families:
Plasticizers – Benefits, Trends, Health, and Environmental
Plasticizers are colorless and odorless esters, mainly phthalates, that increase the elasticity of a material (e.g., polyvinylchloride (PVC)). Plasticizers soften the PVC to make it flexible and bendable. This opens up a huge range of possibilities for new applications.
Plasticizers: Types, Uses, Classification, Selection & Regulation
PVC particles obtained are mixed with plasticizers & can be extruded in pellets which are further used for processing via extrusion, calendaring, injection molding… Processing equipment is typically very expensive Incorporation of an external plasticizer in PVC polymer enhances its flexibility.
- What are plasticizers & how do they work?
- Plasticizers are non-volatile organic substances (mainly liquids) added into a plastic or elastomer. They are also usually cheaper than other additives. They improve the following properties of the polymers: Plasticizers increase the flow and thermoplasticity of a polymer.
- What is a plasticizer chemistry?
- Plasticizers are the most used additives in the plastics industry. They are generally available as non-volatile, colorless liquids. They improve the properties of the polymer. With several plasticizer chemistries available in the market choosing the right one can be daunting. In this guide, you will read more about:
- Why do plasticizers change properties?
- This change is due to the addition of specific additives, especially plasticizers. 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:
- What is plasticization in chemistry?
- The term plasticization refers to the softening and increase in flexibility of a polymer. This change is due to the addition of specific additives, especially plasticizers. A plasticizer is a non-volatile substance incorporated in a plastic or elastomer. It changes the thermal and mechanical properties of the material.
- How do plasticizers affect a polymer?
- Well-chosen plasticizers can also improve resistance to UV exposure and chemical attack. This contributes to the long-term stability of the polymer. In specific applications, plasticizers can influence the dielectric properties of polymers.
- 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.
