Natural-based plasticizers and biopolymer films: A review
The use of natural and/or biodegradable plasticizers, with low toxicity and good compatibility with several plastics, resins, rubber and elastomers in substitution of conventional plasticizers, such as phthalates and other synthetic conventional plasticizers attracted the market along with the increasing worldwide trend towards use of biopolymers.
The Epoxidized Vietnam Rubber Seed Oil as a Secondary
Thus, for the application of plasticizer or secondary heat stabilizer for PVC, scientists previously used rubber seed oil, epoxidized rubber seed oil, metal soaps of rubber seed oil, or epoxidized rubber seed oil [7–9, 11], epoxidized dimeric acid methyl ester [27] as sep- arate or as a combination of metal soap rubber seed oil with epoxidized
Synthesis and application of high-stability bio-based
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. Subsequently, ricinoleate plasticizer, commercially available dioctyl phthalate (DOP), and bis(2-ethylhexyl) adipate (DOA) were
The Epoxidized Vietnam Rubber Seed Oil as a Secondary
Thus, for the application of plasticizer or secondary heat stabilizer for PVC, scientists previously used rubber seed oil, epoxidized rubber seed oil, metal soaps of rubber seed oil, or epoxidized rubber seed oil [ 7 – 9, 11 ], epoxidized dimeric acid methyl ester [ 27] as separate or as a combination of metal soap rubber seed oil with epoxidized
Synthesis and application of a novel environmental C26
The plasticizing effects of C26-DGE as a primary or secondary plasticizer for the commercial plasticizer dioctyl phthalate (DOP) were studied. The mechanical properties, thermal stability, and migration stabilities of PVC films were investigated using dynamic mechanical analysis, thermogravimetric analysis (TGA), TGA-FTIR analysis, and PVC film
- 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.
- Are plasticizers a good choice for PVC?
- According to the statistics, the total output of PVC in the world was over 49.0 million tons in 2019 . However, as a rigid polymer, pure PVC have certain drawbacks without any additives . Therefore, plasticizers are generally blended to improve the mechanical properties and thermal stability of PVC materials , .
- Which plasticizer is used to make polyvinyl chloride (PVC) films?
- Subsequently, ricinoleate plasticizer, commercially available dioctyl phthalate (DOP), and bis (2-ethylhexyl) adipate (DOA) were added to prepare polyvinyl chloride (PVC) films for performance comparison.
- Do plasticizers lubricate PVC film?
- All in all, this also proved that with the increase of plasticizers, the free volume between the PVC molecular chains and the plasticizer increased, and the sliding between the PVC molecular chains was accelerated, making the PVC film more flexible. The Shore hardness data further confirmed the lubricating effect of plasticizers. Table 4.
- Why is PVC plasticized by ricinoleate bio-based plasticizers important?
- The PVC plasticized by the ricinoleate bio-based plasticizers basically showed the minimal migration in various extreme environments. The PVC plasticized by the ricinoleate plasticizers exhibited an outstanding thermal stability.
- What is a good alternative to phthalates in Plasticized PVC?
- The use of natural products, in particular those obtained from vegetable oils and fats, can be considered an adequate and environmentally friendly alternative to phthalates in plasticized PVC . Epoxidized soybean oil (ESBO) is a vegetable oil widely used as plasticizer and/or stabilizer for PVC in food contact materials , , , , .
