Performance assessment of polyvinyl chloride films
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%.
Release of dioctyl phthalate (DOP) from polyvinyl chloride
The release of dioctyl phthalates (DOP) from polyvinyl chloride (PVC) in apples in packaging has been investigated by using a high performance liquid chromatography (HPLC) during the storage. The results indicated that the release amound of DOP increased with time at the room temperature and the amount of DOP transported to the apples reached
Using waste flexible polyvinyl chloride treated with DOP
Calcium hydroxide and dioctyl phthalate (DOP) additives added to PVC absorb chloride radical, so the release of chlorine as HCl is dramatically reduced by additives. In this research, oxidizing bitumen was blended with 2 mass%, 4 mass%, 6 mass%, and 8 mass% of waste PVC.
Effects of dioctyl phthalate on the properties of poly(vinyl
The effects of dioctyl phthalate (DOP) loading on morphology and thermal and mechanical properties of the poly (vinyl chloride)/organically modified montmorillonite/DOP (PVC/O-MMT/DOP) nanocomposites are studied in this paper.
#14 Determination of Plasticizer in PVC by IR or FTIR and a
Dioctyl phthalate (DOP) may reasonably be anticipated to be a carcinogen. Potential symptoms of overexposure are irritation of eyes and mucous membranes. Methanol is a dangerous fire risk and needs to be kept away from open flames. It is also toxic by ingestion. Read the Materials Safety Data Sheets for all chemicals used in this
- Does PVC microplastic release phthalate?
- In this study, the release behavior of phthalate plasticizer from PVC microplastics in aqueous solutions was comprehensively studied. We found that particle size, plasticizer content, aging of plastics, and DOM presence had great effects on phthalate release, while solution pH and ionic strength showed minor effect.
- How do plastic properties affect dibutyl phthalate release?
- It was found that plastic properties, such as particle size, plasticizer content and aging of plastics had a great effect on the leaching of dibutyl phthalate (DnBP). Phthalate release was generally higher in smaller particles and particles with higher phthalate content.
- How do microplastics affect phthalate release?
- More phthalate was released from microplastics with higher phthalate content. Natural aging of plastics led to changed phthalate release. Coexistence of fulvic acid and NaCl had a greater effect on phthalate release than fulvic acid alone. Leaching of surface-active DOC from plastics could promote the release of phthalate plasticizer.
- Does dibutyl phthalate release toxic chemicals and risks associated with microplastics?
- In this study, the release of dibutyl phthalate (di-n -butyl phthalate, DnBP), a commonly used phthalate plasticizer, was targeted. The findings of this study would provide valuable information for evaluation of toxic chemicals and risks associated with microplastics. 2. Materials and methods 2.1. Microplastics
- Do phthalate plasticizers affect DNBP release?
- Collectively, the results demonstrated that the presence of another phthalate plasticizer in plastics did not compromise the beneficial effect of fulvic acid on DnBP release, and the increase of pollutant solubility played a more significant role in the enhanced DnBP release than the increased affinity of leaching solution for microplastics.
- Does fulvic acid accelerate the release of DNBP from PVC microplastics?
- The results clearly demonstrated that the presence of fulvic acid could accelerate the release of DnBP from PVC microplastics. Two reasons might be responsible for that: (1) DOM had a solubilization effect on hydrophobic organic compounds (Chiou et al., 1986), which would facilitate the diffusion of phthalate into water.
