Research progress of novel bio-based plasticizers and their
The resulting epoxy tung oil methyl ester (ETM) and tung-oil-based epoxy plasticizer (TEP) showed better thermal stability and solvent resistance than DOP. Plasticizing efficiency of ETM and TEP reached 104.1% and 101.5%, respectively.
Natural-based plasticizers and biopolymer films: A review
The use of five compounds (GLY, EG, DEG, TEG and PG) as plasticizers for sunflower protein isolate films, producing soft, brown and smooth films, with good mechanical properties and a high level of impermeability to water vapor [49]. No marked loss of GLY or TEG was observed over the 3-month aging period, being both substances the most suitable
Plasticizers: Types, Uses, Classification, Selection & Regulation
It is almost colorless and odorless oily liquid. It is very slightly soluble in water but soluble in alcohols, hexane etc. while miscible and compatible with all the monomeric plasticizers used in PVC compounding. Melting point: 43°C (45°F; 230 K) Boiling point: 244-252°C at 0.7 kPa.
Eastman Product List for General Purpose Plasticizers
Eastman TOTM plasticizer (Tris (2-Ethylhexyl) Trimellitate) is the ideal PVC plasticizer for use in applications where low volatility is of supreme importance, such as wire and cable insulation and interior automotive. It also has properties that are required for dishwasher gaskets and photograph storage.
DOA Plasticizer | Eastman
It can be used alone or blended with other plasticizers, such as DOP or DOTP. In PVC, Eastman DOA features flexibility at low temperatures, good electrical properties, good resistance to weathering, and good stability to heat. Eastman DOA is used to produce clear films for food packaging applications.
- Which plasticizer is most stable after 10 d?
- After 10 d, the migration trend of all samples had been stabled, it showed that the traditional plasticizer like DOP, DOTP and DOA had basically move out from the PVC matrix in non-polar environment due to their own single structure, while the PVC plasticized with A-ODL showed the best stability in all the environment.
- Which plasticizer has a good plasticizing efficiency?
- Both plasticizers provided a satisfactory plasticizing efficiency, such as DEP, due to their low viscosity and ease of diffusion into CA, which enables a large processing window and increases the material's flexibility. CA with 30 wt% GTA displayed a slightly higher elastic modulus than CA with 30 wt% GDA (E = 2.1 GPa and 1.9 GPa, respectively).
- Can ricinoleic acid make a high-stability bio-based plasticizer?
- In this work, a new type of high-stability bio-based plasticizer was obtained by a four-step reaction with ricinoleic acid as main raw material, and its structure was characterized and identified by FT-IR and 1 H NMR.
- Can plasticizers reduce material degradation over time?
- The design of new plasticizers compatible with the polymer at high concentrations, tailored to be effective in lowering the glass transition temperature, and with a low tendency to migration could considerably reduce material degradation over time.
- How can plasticizers be used in industrial applications?
- External plasticization using low molecular weight plasticizers is the most widely applied approach in industrial applications. The glass transition temperatures and the mechanical properties (elastic modulus) of CA systems with different plasticizer contents are reported in Table 2.
- Which substituent has the highest plasticization efficiency?
- The highest plasticization efficiency was observed with substituents consisting of soft segments between the bulky moiety and the cellulose chain compared to soft segments located at the end of the bulky groups directly attached to the cellulose chain. Besides, longer middle segments were more effective in decreasing the Tg.
