Structure‐Performance Guided Design of Sustainable Plasticizers
When studying further performance parameters with the new bio-based plasticizers 1 and 2, we were pleased to find that the investigated plasticizers show excellent compatibility with PVC and that the efficiency of the exo-compound 1 is even better than that of today's commercialized products DINP or Hexamoll DINCH, which can be seen in the low Shore A value (Figure 4).
A Strategy for Nonmigrating Highly Plasticized PVC
This new compound ensured the plasticity of PVC with as high plasticizing efficiency as DOP, without DOP leaking or migration. This approach covalently attaches phthalate to chlorinated...
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.
Plasticisers - Information Center
Ortho-phthalates, due to their high degree of compatibility with PVC, are the most widely consumed plasticisers. As can be seen from these figures, major plasticisers are high volume commodity chemicals, which take decades and billions of Euros to achieve full commercial development.
- Why do plasticizers soften polymer compounds?
- Plasticizers soften polymer compounds in order to improve processing, lower compound viscosity and increase the flexibility of polymer compounds. Because there is a wide range of chemicals used as processing aids and plasticizers, the individual properties of each compounding material can differ greatly.
- What are processing aids & plasticizers?
- Processing aids and plasticizers are chemical additives used in compounds to increase the plasticity, fluidity or lubrication of a material. These processing aids are suitable for use in plastics and rubber compounds.
- Which processing aids are suitable for use in plastics and rubber compounds?
- These processing aids are suitable for use in plastics and rubber compounds. Plasticizers soften polymer compounds in order to improve processing, lower compound viscosity and increase the flexibility of polymer compounds.
- How do plasticizers affect polymers?
- Plasticizers are substances which, by virtue of their polar or polarizable structure, weaken the secondary valence forces of polymers. By adding plasticizers to compatible polymers, the materials can be modified in such a way that they become soft and flexible by decreasing their glass transition temperature.
- How are plasticizers classified?
- Plasticizers are classified according to their molecular structure into monomeric or polymeric types. The choice of the plasticizer is dependent on the requirements that have to be met for the final product and the conditions around that product’s use.
- How to choose a plasticizer?
- The choice of the plasticizer is dependent on the requirements that have to be met for the final product and the conditions around that product’s use. This may include low volatility, high permanence, low temperature flexibility, flame retardancy, high thermal stability and saponification resistance.
