Bio-Based Plasticizers for Polyvinylchloride (PVC) | SpringerLink
Among phthalate esters, di- (2-ethylhexyl) phthalate (DEHP) is the widely used plasticizer in order to give the necessary flexibility for PVC compounds from medical devices such as medical tubing and blood bags [ 7, 8 ], to footwear, electrical cables, packaging, and flooring.
DEHT is a suitable plasticizer option for phthalate-free
Of the four combinations, membrane stability was least impacted in DEHP/PAGGSM. Conclusion: We demonstrate that DEHT is a suitable plasticizer for storage of RBCs after X-ray irradiation cell stress. This strengthens the option of DEHT as a viable non-phthalate substitute for DEHP.

The three prominent PVC plasticizers are DEHP, DINP and DIDP and they are all dialkyl ortho-phthalates. Over the last 60 years, the most common plasticizer used to soften PVC compounds used for medical devices has been DEHP Di-2 ethyl hexyl phthalate. DEHP is economical and offers excellent performance (e.g., compatibility with PVC, plasticizer
Non-phthalate plasticizer DEHT preserves adequate blood
Materials and methods: RBC concentrates (N = 64), platelet concentrates (N = 16) and fresh frozen plasma (N = 32) were produced from whole blood collected into either DEHT or DEHP plasticized systems. Using a pool-and-split study design, pairs of identical RBC content were created within each plasticizer arm and assigned either SAGM or PAGGSM.
Plasticizers: Types, Uses, Classification, Selection & Regulation
DEHP offers good gelling, satisfactory electrical properties and helps to produce highly elastic compounds with reasonable cold strength. It displays fairly good flexibility at low temperatures and some resistance to high-temperature. However, DEHP is listed by the IARC as a human carcinogen.
- 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.
- What is re-placement of Di(2-ethylhexyl) phthalate (DEHP) plasticizer?
- ABSTRACT: Environmental and toxicity concerns dictate re-placement of di(2-ethylhexyl) phthalate (DEHP) plasticizer used to impart flexibility and thermal stability to polyvinyl chloride (PVC).
- 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.
- Why is DEHP used in plasticization and processing of PVC?
- The excellent performance of DEHP in the plasticization and processing of PVC explains its wide use in medical devices over the past few years. The strategy was to adjust the chemical nature of the lateral alkyl chains in order to reduce the leaching of the plasticizers into the surrounding medium.
- Are DBS and DHS a good plasticizer for PVC?
- Where data was available, the results from this study are in good agreement with the experiment; we conclude that DBS and DHS are most promising green plasticizers for PVC, since they have properties comparable to DEHP but not the environmental and toxicity concerns.
- 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.
