DPHP plasticization grants PVC with a better low-temperature tenacity than DOP and with a lower brittle temperature than DIDP, indicating the better low-temperature performance of DPHP. Based on its high mechanical performance, DPHP can be used in PVC as a primary plasticizer.
A Strategy for Nonmigrating Highly Plasticized PVC - Nature
Nonmigrating highly plasticized PVC was prepared based on a new compound that acts as a plasticizer that was derived from di (2-ethylhexyl) 4-hydrophthalate and chlorinated paraffin-52. The...
What is DEHP? Where is it used? Why is it used? | U.S. Plastic
Plasticizers are essential to make PVC flexible. PVC is naturally rigid, but plasticizers are added to make the tubing flexible and expandable while retaining its shape. DEHP is widely used because it is low cost, processes well, and has provided good end-use performance.
Plasticizer for poly(vinyl chloride) from cardanol as a
High purity, small scale esterification was performed in order to study the plasticizing effectiveness of the derived plasticizer, but let us produce no more than 7.5 g of plasticizer. This high purity esterification was obtained using, 7 g of cardanol and 6.57 ml (7.09 mol, 3 equivalents) of acetic anhydride, diluted in 5 ml di pyridine, and
Plasticizers for the PVC industry are now also available
BASF now offers part of its plasticizer portfolio based on circular feedstocks. For this purpose, either renewable or chemically recycled feedstock is used at the beginning of the value chain instead of fossil resources. The alternative feedstock is allocated to the sales products according to a mass balance approach.
- What is nonmigrating highly plasticized PVC?
- Nonmigrating highly plasticized PVC was prepared based on a new compound that acts as a plasticizer that was derived from di (2-ethylhexyl) 4-hydrophthalate and chlorinated paraffin-52. The as-prepared PVC has a plasticizing efficiency as high as DOP and its migration is totally suppressed.
- Which plasticizer has a low plasticizing efficiency?
- Polymeric plasticizer generally has low plasticizing efficiency. Navarro et al. 35 replaced the chlorine on the PVC backbone via nucleophilic substitution of thiol groups attached to the benzene ring of di (2-ethylhexyl)phthalate (also known as dioctyl phthalate, DOP, the most common plasticizer), to give totally nonleachable PVC.
- Why do we need plasticizers in polyvinyl chloride (PVC)?
- Plasticizers play a crucial role in the overall performance and usability of polyvinyl chloride (PVC). Their addition can significantly alter the mechanical properties of PVC, thereby expanding its application range.
- Is PVC a plasticizer?
- The low molecular weight compound was defined as a plasticizer by The Council of the International Union of Pure and Applied Chemistry. Internally plasticized PVC can maintain its performance over long-term use because there is no plasticizer migration.
- What makes a good plasticizer?
- A good plasticizer must blend uniformly with the PVC matrix, ensuring that it does not phase-separate or lead to inconsistency in the material properties. An effective means to evaluate compatibility is through the analysis of: Solubility: The plasticizer should dissolve in PVC without forming precipitates.
- Does a mixture of Plasticizers improve the mechanical properties of PVC?
- Moreover, the mechanical properties were improved when a mixture of plasticizers was applied in PVC blends, whereas a blend with pure SOHE showed worse mechanical properties (lower elongation at break and higher tensile strength) than DOP.
