Mechanical properties evaluation of PVC/plasticizers and PVC
The stress–strain curves in tension of PVC/DOP blends prepared at 30 rpm are shown in Fig. 1.These results are typical for hard and brittle materials for blends with 10 phr of DOP, soft and tough for mixtures with 50 and 90 phr.
A Strategy for Nonmigrating Highly Plasticized PVC
With higher DOP-O-CP52 levels in PVC, CP52 in DOP-O-CP52 will form microclusters owing to their lower compatibility with PVC, to retard the movement of DOP-O-CP52 in PVC, resulting in...
Structure Design, Performance Simulation and Plasticizing
Based on the definition of plasticization, the T g of PVC blends is expected to be decreased with the addition of a plasticizer, and as observed from Fig. 3b, T g of PVC blends plasticized by copolyester is close to or lower than that of DOP, which indicates the novel copolyester plasticizer could have the same performance as DOP in many applications.
Performance assessment of polyvinyl chloride films plasticized with
Polyvinyl chloride (PVC) films were synthesized using different concentrations of ECLO. At 40% of ECLO, films showed better surface morphology and exhibited maximum strength and elongation at break. Plasticized PVC film shown tensile strength of 18.6 MPa and elongation at break of 136.18%.
DIDP plasticizer | ExxonMobil Product Solutions
Jayflex DIDP plasticizer is an excellent substitute for Di (2-ethylhexyl) phthalate (DOP) in most flexible PVC applications. Jayflex DIDP plasticizer can also be of benefit when used with other non-PVC polymers such as polyurethanes or polyacrylates used in coatings, sealants and mastic applications. Higher permanency for better resistance
- How to choose a plasticizer for PVC?
- Using external plasticizers, it is very convenient to select from a variety of plasticizers depending on the desired properties and processability of PVC. Plasticizer is not only a processing aid but also an important component to determine the performance and application of PVC.
- Does cp52 interact with PVC?
- Combining CP52 and DOP into one molecule undoubtedly increases DOP’s interaction with PVC, resulting in DOP’s high permanence in PVC. However, stronger interactions between plasticizer and PVC will reduce its rate of diffusion in PVC, leading to lower plasticizing efficiency.
- How does cp52 affect plasticization efficiency?
- With higher DOP-O-CP52 levels in PVC, CP52 in DOP-O-CP52 will form microclusters owing to their lower compatibility with PVC, to retard the movement of DOP-O-CP52 in PVC, resulting in a decline in plasticizing efficiency. Figure 6 shown the extraction of plasticized PVCs.
- 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.
- Is cp52 better than DOP-o-cp52?
- A compromise is achieved using DOP-O-CP52, yielding PVC with no migration and high plasticization. CP52 appears to be a better choice for DOP. The interaction between CP52 and PVC is appropriately strong to maintain both the plasticization and nonmigration of DOP-O-CP52.
