What is the best alternative to DEHP for medical-grade PVC
In addition, TOTM is a much less efficient plasticizer than DOTP, meaning you have to use more TOTM to achieve the same durometer—and plasticizer today is more expensive than PVC resin. Purity. If processed in truly dedicated equipment, DOTP can be produced nearly free of DEHP contamination.
Health, Eco Concerns Give Non-Phthalate Plasticizers a Push
DOTP and Hexamoll DINCH are two leading non-phthalate alternatives gaining significant ground. DOTP from Eastman has been available for several decades as Eastman 168, and the company claims it is the market-leading non-phthalate plasticizer for PVC, offering performance equal to or better than most non-phthalates.
PVC Plasticizers and Stabilizers Following Safer Sustainable
Traditional low molecular weight plasticizer types include: DEHP (DiEthylHexylPhthalate) DIBP (DiIsoButylPhthalate) DBP (DiButylPhthalate), and BBP (BenzylButylPhthalate) High molecular weight orthophthalates and alternative bio-based plasticizers are the emerging replacement choices.
Bis(2-ethylhexyl) terephthalate
Bis (2-ethylhexyl) terephthalate commonly abbreviated DEHT (Dioctyl terephthalate or DOTP), is an organic compound with the formula C 6 H 4 (CO 2 C 8 H 17) 2. It is a non- phthalate plasticizer, being the diester of terephthalic acid and the branched-chain 2-ethylhexanol, which is referred to as octyl.
Alternative plasticizer - DOTP | ChemSec Marketplace
DOTP - dioctyl terephthalate - phthalate free plasticizer alternative. The colorless viscous liquid is used for softening PVC plastics and is known for chemical similarity to general purpose phthalates such as DEHP and DINP, but without any negative regulatory pressure. It possesses very good plasticizing properties and may be used as a direct
- Do alternative plasticizers metabolize phthalates and DINCH?
- For instance, the human metabolism of phthalates and DINCH is well known. Therefore, exposure to these substances can be well assessed by measuring relevant metabolites in human matrices like blood or urine. Unfortunately, this has not been done for all relevant alternative plasticizers.
- What are alternative plasticizers?
- Extensive research has been performed to identify alternatives for PEs. Currently, many different alternative plasticizers exist including adipates, benzoates, citrates, cyclohexane dicarboxylic acids, epoxidized vegetable oils, glycerol acetylated esters, phosphate esters, sebacates, terephthalates and trimellitates.
- Can plasticizers be used as ortho-phthalates?
- Several plasticizers are identified and discussed in the paper. All may be used as plasticizers, but only some are considered alternatives to general purpose ortho-phthalates such as DEHP and DINP, while the others are specialty plasticizers with niche uses.
- Are alternative plasticizers toxic?
- For this reason, we were surprised by the content and quality of the article. The authors state that alternative plasticizers have been introduced into the market without a complete understanding of their toxicities; however, this is clearly incorrect.
- Where can I find toxicological data for alternative plasticizers?
- For all selected alternative plasticizers, toxicological information is available to a certain extent. Since these substances are produced in high volumes, toxicological data are required in the EU and could be found in the ECHA database for registered substances (ECHA, 2014b).
- Are alternative plasticizers phthalate or phosphate esters?
- Additionally, some substances are not exclusively being used as plasticizers. For example, phosphate esters have also been widely used as flame retardants (Marklund et al., 2003, Wei et al., 2015). In this work, we consider the term “alternative plasticizer” as a synonym for non-phthalate plasticizers.
