Synthesis and properties of a bio-based PVC plasticizer
The use of non-toxic and biodegradable alternatives to replace phthalates has become an inevitable trend. 25–27 Currently, hundreds of plasticizers obtained from renewable bio-based resources have been commercially used, such as epoxy soybean oil plasticizer, 28,29 epoxidized glycidyl ester of ricinoleic acetic ester, 30 epoxidized tung oil
Synthesis of novel plasticizer ester end-capped oligomeric
In this work, a novel high efficiency plasticizer, an ester-capped oligomeric lactic acid mixture (EOL), was successfully synthesized by a two-step esterification reaction, with L -lactic acid as the main raw material. The structure of EOL was characterized by using FT-IR, 1 H NMR and time of flight mass spectrometry (TOF-MS).
A new plasticizer for phthalate-free
A new plasticizer for phthalate-free solutions in PVC May 1, 2015 | By Chemical Engineering With a key plasticizer, dioctyl phthalate (DOP), no longer permitted under European Union REA CH regulations after February of this year, polyvinyl chloride (PVC) compounders and processors will have to move to safer alternatives.
Nonphthalate Plasticizers in House Dust from Multiple
In 2017, the phthalate-free plasticizers accounted for 35% of global plasticizer consumption, up from 12% in 2005, and were expected to increase to 40% in 2025. (9,10) NPPs are complex in chemical structures, mainly containing functional groups such as benzoate, sebacate, azelate, adipate, terephthalate, trimellitate, citrate, oleate, and a few
Recent Developments of Biobased Plasticizers and Their Effect
Phthalates have been the most commonly employed plasticizers for PVC, but some of these plasticizers demonstrate many toxic effects on the environment and human beings, which consequently limits the use of phthalate plasticizers.
- Are phthalate plasticizers safe?
- However, the phthalate content in plasticizer is known to be toxic to humans. Therefore, its use is prohibited in wallpapers, flooring materials, toys and many other products. Dioctyl terephthalate (DOTP) plasticizers are used as an alternative, but done so at the expense of product quality.
- How many chemicals can be used as plasticizers?
- There are about 30 000 chemicals can potentially be utilized as plasticizers. (1) Phthalate plasticizers are a commonly utilized compound, comprising up to 85% of the total plasticizers in the market.
- Are hydrogen-added plasticizers eco-friendly?
- As the production of eco-friendly plasticizers require advanced technology, the barrier to entry is high and its key strengths and strong value proposition assures there is no concern for oversupply. The hydrogen-added plasticizer is currently being manufactured by only two companies in the world: BASF and EVONIK.
- Are there alternative plasticizers?
- There are a considerable number of alternative plasticizers in employment, without any toxicological data available (dibutyl adipate, diethylene glycol dibenzoate, and bis-2-ethylhexyl sebacate, to name a few).
- What is Cargill bioindustrial plasticizer?
- The plasticizer joins a diverse portfolio of Cargill Bioindustrial plant-based solutions, ranging from asphalt rejuvenation, adhesives and binders, wax, dielectric fluids, lubricants and paints, coatings and inks.
- Are plasticizers toxic?
- Plasticizers are additives that soften and thereby improve the flexibility of plastics. However, the phthalate content in plasticizer is known to be toxic to humans. Therefore, its use is prohibited in wallpapers, flooring materials, toys and many other products.
