Does that 'green' plasticizer make my PVC flexible enough
A study of an eco-friendly solvent helping to make PVC plastic more flexible reveals the molecular-level interaction of hydrogen bonds between the two ingredients. What gives plastic objects...
Research progress of novel bio-based plasticizers and their
Researchers prepared PVC films plasticized by AC-FAME-MAE and DOP respectively. The plasticizing efficiency of AC-FAME-MAE was 98.8%. By comparison, the elongation at break of AC-FAME-MAE/PVC was higher than DOP/PVC, as shown in Fig. 4. According to the results of food simulation, AC-FAME-MAE was more suitable for food package.
A Strategy for Nonmigrating Highly Plasticized PVC - Nature
Glass Transition Temperature. As shown in Fig. 5, glass temperatures (Tgs) of DOP-plasticized and DOP-O-CP52-plasticized PVC were studied with respect to the ratio of plasticizers to PVC.Both Tgs
Poly(vinyl chloride) plasticized with succinate esters
Phthalates pose adverse health effects due to their propensity to leach and the most common, di(2-ethylhexyl) phthalate (DEHP) and di-n-octyl phthalate (DOP), are petroleum-based. Conversely, di-esters, succinates are biobased (produced from fermentation of biomass), biodegradable, and therefore potential sustainable replacements for phthalates. A series of succinates, di-octyl succinate (DOS
Mechanical properties evaluation of PVC/plasticizers and PVC
Fig. 4, Fig. 5, Fig. 6 showed that Young's modulus for PVC/DOP, PVC/DIDP and PVC/TPU blends decreased with the second component content. As expected, the addition of low-molecular-weight plasticizer to a PVC formulation decreases the modulus of the PVC product.
- 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 -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).
- How did Navarro et al 35 replace chlorine on PVC backbone?
- 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.
- Which PVC samples are buried in activated carbon?
- In the volatility tests, all PVC samples were buried in activated carbon. After 240 h, the migration rates of DOP-50 and DOTP-50 were above 10.00%, while the migration rates of all ALCE-plasticized samples remained within 7.00%. Specifically, the migration rates for ALCE-40, ALCE-50, and ALCE-60 were 6.97%, 6.24%, and 4.85%, respectively.
- Is PVC safe for food packaging?
- The food packaging industry is a significant application area for PVC products. Since food packaging materials come into direct or indirect contact with food, the safety of these materials has attracted widespread attention .
