Non-phthalate plasticizer from camphor for flexible PVC with
Pyeon et al. 99 (Figure 16) plasticized with flexible PVC and studied its compatibility with PVC, thermal and mechanical properties, and its application to replace the commercial phthalate
Non-phthalate plasticizer from camphor for flexible PVC with
The effect of the plasticizer on PVC was obtained by introducing a linear alkyl chain without branches into a camphor body. The camphor body has a bridged, six-membered ring structure and is rigid; thus, it exhibits improved thermal stability.
Diverging trends of plasticizers (phthalates and non
High-volume industrial chemicals include plasticizers (global production in 2018: 7.45 Mt ), the main additives for flexible PVC. The use of some phthalate plasticizers has been successively restricted in the EU since the late 1990s due to their endocrine disrupting (ED) properties, especially in sensitive applications for humans, such as baby
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...
Perspectives on alternatives to phthalate plasticized poly
The most widely used PVC plasticizers are phthalate esters, particularly di-(2-ethylhexyl) phthalate (DEHP), which usually represent up to 40–50% of the weight of the plastic items. Phthalates account for 80% of all plasticizer production [6] while DEHP is responsible for over 50% of worldwide phthalate production [7].
- Are phthalate plasticizers good for PVC?
- Phthalate plasticizers have been the conventional choice in the PVC industry for many years. They improve the flexibility and processability of PVC, making it suitable for a wide range of applications, such as pipes, vinyl flooring, and medical devices.
- What are phthalate plasticizers used for?
- They improve the flexibility and processability of PVC, making it suitable for a wide range of applications, such as pipes, vinyl flooring, and medical devices. Common phthalate plasticizers include DOP (di-octyl phthalate) and DEHP (di-ethylhexyl phthalate).
- Are phthalate-free plasticizers safe?
- In response to consumer and regulatory pressures, developing nonmigrating or phthalate-free PVC is very active in past few years. Recently, some other plasticizers instead of phthalate plasticizers, such as biocompatible material and oligomer 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, have been reported without toxicity.
- Is -caprolactone a nonmigrating plasticizer for phthalates in flexible PVC?
- Toxicological Sciences. 71 (2), 146–153 (2003). Choi, J. & Kwak, S. Y. Hyperbranched poly (ε-caprolactone) as a nonmigrating alternative plasticizer for phthalates in flexible PVC. Environmental science & technology. 41 (10), 3763–3768 (2007).
- Are phthalate plasticizers chemically bonded to polymer chains?
- However, phthalate plasticizers such as DOP are not chemically bonded to polymer chains, allowing them to easily detach from objects, resulting in human exposure through inhalation, ingestion, and skin contact , .
- Why is a camphor body a plasticizer?
- The camphor body has a bridged, six-membered ring structure and is rigid; thus, it exhibits improved thermal stability. The two alkyl chains were connected to the ketal group in one direction of the camphor body, and the plasticizer was formed like a pincer.
