Sebacic Acid Dibutyl Ester - an overview | ScienceDirect Topics
3.1.1.1 Dibutyl sebacate (DBS) This is the first choice of plasticizer for non-aqueous and aqueous system due to its better plasticizing efficiency compared to other plasticizers. DBS is practically insoluble in water, which significantly reduces its leaching from the film, when exposed to aqueous media.
Thermo-mechanical characterization of plasticized PLA: Is the
When plasticizers (PBOH, AGM and DBS) are blended higher for 30% to PLA, tensile modulus or strain at break are stable in comparison to 20% and the stress at break is slightly reduced. In light of these results, the most efficient plasticized formulations are AGM, PBOH and DBS at 20 to 30% according to the mechanical requirements.
Ionic liquids: New generation stable plasticizers for poly(vinyl
Structures of ILs and traditional plasticizers. The effectiveness of these ILs and traditional plasticizers were studied in terms of flexibility, mechanical properties, and high temperature and UV stability they impart to PVC as plasticizers. The leaching and migration tendencies of these plasticizers were also investigated.
Plasticizer
Some common phthalate plasticizers are: Low Molecular Weight Ortho Phthalates Dimethyl phthalate (DMP), used in fragrances, as an insect repellent, and in several industrial processes as a solvent/carrier Diethyl phthalate (DEP), used in fragrances as a carrier and extender/fixative Diisobutyl phthalate (DIBP)
Widespread occurrence of phthalate and non-phthalate plasticizers
Among all plasticizers analyzed, DBS was found at the highest mean concentration, 3350 ± 2130 ng/g. This is the first study to report adipates and DBS in facemasks. Due to increasing concern over endocrine-disrupting properties of phthalates, substitute plasticizers such as DBS are becoming more widely used in consumer products.
- Are DBS & DHS a good plasticizer?
- The consensus from this series of simulations on bulk moduli, difusion, and thermal stability is that the plasticizer perform-ance of DBS and DHS in PVC are both is at the same level or better than DEHP. Furthermore, both DBS and DHS have been shown to be nontoxic while DHS is biodegradable and can be sourced from renewable feedstock.
- Can DBS replace DEHP as a plasticizer?
- Furthermore, both DBS and DHS have been shown to be nontoxic while DHS is biodegradable and can be sourced from renewable feedstock. This leads us to conclude that DHS and DBS are excellent candidates for replacing DEHP as a plasticizer. In practice, other knowledge of other properties is required to ensure suitability for industrial production.
- Can bio-based plasticizers compete with DEHP in PVC?
- Potential alternatives to DEHP in PVC include diheptyl succinate (DHS), diethyl adipate (DEA), 1,4-butanediol dibenzoate (1,4-BDB), and dibutyl sebacate (DBS). To examine whether that these bio-based plasticizers can compete with DEHP, we need to compare their tensile, mechanical, and difusional properties.
- Are dibutyl sebacate and diheptyl succinate plasticizers toxic?
- Our studies indicate that dibutyl sebacate (DBS) and diheptyl succinate (DHS) plasticizers have properties comparable to DEHP but none of the toxic attributes of DEHP. Thus, we recommend the gradual switch from DEHP to DBS or DHS. ACS Appl. Mater. Interfaces 2023, 15, 24858−24867 1.1. Efect of Structure on Plasticization.
- Which plasticizer has a lower Young's modulus at room temperature?
- Indeed DBS and DHS were the only plasticizers that lead to a lower Young’s modulus than DEHP at room temperature (∼298 K).15 A dramatic decrease in E(x) at some temperatures was observed in all systems.
- Does PVC mix with DBS DEA & 1 4 BDB?
- We found no literature regarding PVC blends with DBS, DEA, and 1,4-BDB. Our calculated E(T) for 40 wt % DEHP is higher than the values measured by Kendall and Siviour48 which have 40 wt % DINP and those calculated by Zhou and Milner49 which have 40 wt % DEHP (Figure 3).
