Widespread occurrence of phthalate and non-phthalate
Besides phthalates, adipates, tributyl phosphate (TBP) and dibutyl sebacate (DBS), are used as plasticizers in synthetic polymers ( EU, 2008, LCSP, 2011 ). Adipates (especially, di (2-ethylhexyl)adipate; DEHA) and DBS are used in soft plastics, especially food wraps and films.
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.
Plasticizer
A plasticizer ( UK: plasticiser) is a substance that is added to a material to make it softer and more flexible, to increase its plasticity, to decrease its viscosity, and/or to decrease friction during its handling in manufacture. Plasticizers are commonly added to polymers such as plastics and rubber, either to facilitate the handling of the
Effect of plasticizer on the electric-field-induced adhesion
The dielectric constant of the plasticizers depends on their molecular weight, and the higher molecular weight plasticizers (DBS and DOP) had lower dielectric constants than those with low molecular weight (DEA and DBP). This suggests that molecular motion is restricted by the molecular weight.
Mechanical and Thermal Properties of the Plasticized
These results suggested mesh size of gel network near the gelation point for PVC with bis(2-ethylhexyl) phthalate (DOP) or di-n-butyl sebacate (DBS) plasticizers that has been newly reported. Read
- 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.
- Is diol dibenzoate a viable alternative plasticizer?
- The diol dibenzoate family of compounds is of interest in the search for viable alternative plasticizers because diethylene glycol dibenzoate (DEGDB) is already in wide commercial use. However, there is concern that its ether linkages may lead to the formation of metabolites that are dificult to degrade microbially.
- Could diheptyl succinate be a bio-based plasticizer?
- The above results show the promise of diheptyl succinate, diethyl adipate, 1,4-butanediol dibenzoate, and dibutyl sebacate as potential alternatives to DEHP in PVC (Table 1). In addition, numerous investigations have been made into other potential bio-based plasticizers.
