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. One of the main benefits of plasticizers is the durability they confer onto
Why Plasticizer free - Action Products
Why Plasticizer-Free? DEHP, a phthalate plasticizer used to soften PVC, may leach out from the material and is linked to reproductive birth defects and other harmful effects, according to animal studies. Tests have shown that some plasticizers can “interfere with male reproductive tract development and are toxic to cells in the
Plasticizer - an overview | ScienceDirect Topics
Plasticizer loss causes plasticized PVC to shrink and become stiff. This can occur quickly at room temperature with low-molecular-weight plasticizers. As the molecular weight of plasticizer is increased, permanence at room or elevated temperature improves.
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.
Trimellitate plasticizers | ExxonMobil Product Solutions
Fact sheet: New solutions for flexible PVC products used under extreme conditions. ExxonMobil has expanded its portfolio of high molecular weight plasticizers with the introduction of Jayflex L9TM, a trinonyl trimellitate based on linear and branched C9 alcohol. It shows excellent attributes that can meet the needs of extreme flexible PVC
- Why does adding a plasticizer molecule increase the free volume?
- Adding a plasticizer molecule increases the free volume per total volume due to a proportional increase in end groups. The free volume theory explains the lowering of the glass transition temperature with an increase in free space within the polymer.
- Why are plasticizers important in biopolymer-based films & coatings production?
- In biopolymer-based films and coatings production, plasticizers are also essential additives since they can improve flexibility and handling of films, maintain integrity and avoid pores and cracks in the polymeric matrix .
- Why are plasticizers added to ca?
- Plasticizers are added to CA to increase workability, prevent degradation under processing conditions and ensure thermo-mechanical properties suitable for the intended final application. Moreover, inexpensive and non-toxic solvents enable its processing into fibers, films, and solid blocks.
- Which plasticizers are used in stretch PVC films?
- Considering the tensile properties, all samples will probably show adequate performance when used as stretch PVC films with slight differences between them as follows: The plasticizers ATBC, DEHT and polyadipate showed lower plasticization efficiency than the others since samples 2, 4 and 6 showed the highest tensile strength values.
- Why do we add plasticizer?
- The addition of plasticizer leads to a decrease in intermolecular forces along polymer chains, which improves the flexibility and chain mobility. These are added to enhance film flexibility, decrease brittleness and avoid shrinking during handling and storage , , .
- Which plasticizer has a good plasticizing efficiency?
- Both plasticizers provided a satisfactory plasticizing efficiency, such as DEP, due to their low viscosity and ease of diffusion into CA, which enables a large processing window and increases the material's flexibility. CA with 30 wt% GTA displayed a slightly higher elastic modulus than CA with 30 wt% GDA (E = 2.1 GPa and 1.9 GPa, respectively).
