Designing anti-migration furan-based plasticizers and their
Plasticizer, one of the most important additives for PVC industry, which penetrates into our life fields, including agriculture, transportation, construction, clothing, food packaging, pharmaceutical materials and so on, has increased attention at present [1, 2]. Among all plasticizers, phthalate esters (PAEs) accounted for 80% of the total
Research progress of novel bio-based plasticizers and their
Vegetable oil-based plasticizers Vegetable oils such as soybean oil, peanut oil, castor oil, tung oil, palm oil and so on which are generally extracted from plant seeds and germ, are widely distributed in nature [ 26 ]. The main components of vegetable oil are straight-chain higher fatty acids and glycerides [ 27, 28, 29 ].
Synthesis of Plasticizers Derived from Palm Oil and Their
The PVC plastics were formulated using the commercial and commonly used plasticizer (DEHP) and the secondary plasticizers based on palm oil components. The addition effects of secondary...
Phthalate
Phthalates ( US: / θlets /, [1] UK: / θɑlets fθlts / [2] [3] ), or phthalate esters, are esters of phthalic acid. They are mainly used as plasticizers, i.e., substances added to plastics to increase their flexibility, transparency, durability, and longevity. They are used primarily to soften polyvinyl chloride (PVC).
Plasticizers Derived from Biomass Resources: A Short Review.
Polyvinyl chloride (PVC) plasticizers derived from biomass resources (vegetable oil, cardanol, vegetable fatty acid, glycerol and citric acid) have been widely studied to replace petroleum-based o-phthalate plasticizers.
- What is a safe plasticizer substitute for phthalate esters in PVC?
- Of all these options, vegetable oils (refined or used) and their derivatives, like fatty acid alkyl esters (biodiesel) and free fatty acids, are some of the most promising raw materials for producing safe plasticizer substitutes for toxic phthalate esters in PVC and other polymers [7, , , , ].
- Which phthalate is used as a plasticizer?
- Traditionally, phthalate esters, most prominently, di (2-ethylhexyl) phthalate [DEHP], have been used as plasticizers. DEHP is produced from two inexpensive precursors, phthalic acid and 2-ethylhexanol. Phthalic acid is obtained from the oxidation of o -xylene, the least useful of the mixed xylenes from the reforming of naphtha .
- What is a nonmigrating plasticizer?
- Most prominently, hyperbranched oligomeric esters derived from the readily available, renewable, nontoxic biomonomers, glycerol and adipic acid, are excellent nonmigrating plasticizers. These materials may be produced in a simple process.
- What plasticizers are used in PVC?
- The most common plasticizers for PVC products are phthalic esters (or phthalates), an important class of synthetic chemicals produced from petroleum-derived phthalic anhydride and alcohols.
- Is liquefied wood flour ester a good plasticizer?
- The liquefied wood flour ester (PWF) showed good miscibility with PLA and good plasticization efficiency as shown by differential scanning calorimetry (DSC) and tensile testing. Tensile strain at break increased from a few percent for pure PLA to over 100 and 300% for the materials containing 10 and 30 wt-% of PWF.
- Do epoxidized benzyl esters provide flexible PVC films?
- Epoxidized benzyl esters provided flexible PVC films with favorable properties. The objective of this study was to produce new and renewable bio-based plasticizers from used soybean cooking oil (USCO). First, USCO was completely converted into free fatty acids (FFAs) using lipase from Candida rugosa.
