Chemistry can help make plastics sustainable — but it isn’t
It could be a part of the solution to making plastics use less harmful. But chemistry alone can take us only so far. If the burning of plastics and the accumulation of the materials in oceans and
Research progress of novel bio-based plasticizers and their
On the other hand, these new bio-based plasticizers can also ameliorate mechanical and thermal properties of PVC like traditional plasticizers, and are eco-friendly, low priori toxic and resistant to migration. Thus, preparing high performance bio-based plasticizers will still be a research hotspot in this field for a long time.
Hanwha Solutions' phthalate-free plasticizer Eco-DEHCH offers
Eco-DEHCH is one of the most recognized phthalate-free plasticizer developed by a research team at Hanwha Solutions’ Chemical Division, providing eco-friendly alternative for hazardous dioctyl phthalate (DOP) and less-harmful but less-effective terephthalate like dioctyl terephthalate (DOTP).
Synthesis and properties of castor oil based plasticizers
Synthesis of acetylated castor oil (ACO) Castor oil (93.4 g) and acetic anhydride (27.5 g) were added to a 500 mL four-necked flask, and were stirred at 140 °C for 2 h. Then the reaction mixture was washed to pH = 7 with sodium carbonate solution and distilled water. Then the water was removed by vacuum distillation.
Developments of biobased plasticizers for compostable
The development and utilization of biobased plasticizers derived from epoxidized soybean oil, castor oil, cardanol, citrate, and isosorbide have been broadly investigated. The synthesis of...
- Is bioplasticizer a good alternative to plasticizers?
- The bioplasticizer, when incorporated into a PLA film at 1.0%, exhibited high tensile strength, tensile modulus, and an elongation percentage of 22.21 MPa, 12.29 MPa, and 22.74%, respectively, highlighting its potential as a practical, eco-friendly alternative to traditional plasticizers (Narayana Perumal et al., 2023). 7.6.3. From lignin
- What are alternative plasticizers?
- Alternative plasticizers are still being sought, including oils such as palm oil (Hasan et al., 2020), rosehip seed oil (Darie-Niță et al., 2021), epoxidized chia seed oil (Dominguez-Candela et al., 2021), epoxidized soybean oil (Alhanish & Abu Ghalia, 2021) olive oil or corn oil ( Giannakas et al., 2017) and fatty acids ( Srinivasa et al., 2007 ).
- What is a biodegradable plasticizer?
- Tall oil, a byproduct of the Kraft process, is also used to make bioplasticizers. Citric acid (CA) from sugarcane, beets, or citrus fruits is a popular starting material for many natural plasticizers. Other molecules that have been studied as biodegradable plasticizers include amino acids, waxes, and lecithin.
- Are bioplasticizers a sustainable alternative to fossil-fuel based plasticizers?
- Conclusion To sum up, bioplasticizers present a significant opportunity as an eco-friendly and sustainable substitute for conventional fossil-fuel-derived plasticizers, enhancing polymer flexibility. Their biodegradable nature and low toxicity make them suitable for a variety of uses, including food-safe packaging and medical devices.
- Are bioplasticizers biodegradable?
- Bioplasticizers are less synthetic chemicals and are biodegradable. In wire applications, the use of bioplasticizers was able to reduce carbon emissions by up to 40%. Plasticizers are the most common plastic additives. The production of plasticizers from vegetable oils is slowly replacing the plasticizers produced by petroleum products.
- Which plasticizer has the best mechanical properties?
- Of the plasticizers we synthesized, the best film mechanical properties were provided by OC plasticizer, containing primarily propylene glycol monoacetate, but also propylene glycol diacetate, acetic acid and propylene glycol in its mixture.
