New Dibenzoate Plasticizer Blends for PVC Applications
Dibenzoates plasticizers are well-established and are used in PVC applications. Chemically, these plasticizers are non-phthalates and function well as high-solvating. In the past, new benzoates
Plasticizers: Types, Uses, Classification, Selection & Regulation
Most common plasticiser chemistries include citrates, benzoates, ortho-phthalates, terephthalates, adipates, azelates, sebacates, and trimellitates. Plasticizers are the most common additives used in the plastics industry. But, selecting the right plasticizer for an application has always been a daunting task.
Plasticizer - an overview | ScienceDirect Topics
These products generally use a mixture of plasticizers such as DIHP, DEHP, DINP, and DEHTP often in blends with faster fusing plasticizers such as monobenzoates, dibenzoates, or BBP. Vinyl floor tiles and other sheet flooring are produced by calendering; again GP plasticizers, often used in blends with fast-fusing plasticizers, are commonly used.
Benzoates (NK Series) – Nayakem
NK-250 is a proprietary blend of Diethylene Glycol Dibenzoate and DiPropylene Glycol DiBenzoate. It is a non-phthalate, Benzoate plasticizer and is a good substitute for solvating phthalates like DBP and BBP. It is a polar plasticizer that is a high solvated for PVC applications.
- What is a dibenzoate plasticizer?
- While several commercial dibenzoate plasticizers, such as diethylene glycol dibenzoate (DEGDB) and dipropylene glycol dibenzoate (DPGDB; see Figure 2), are sold commercially [18, 19], these compounds generally contain ether linkages in their central linker connecting the two benzoate moieties.
- Is dibenzoate plasticizer effective in poly (vinyl chloride)?
- 4.1. Dibenzoate Plasticizer Effectiveness in Poly (Vinyl Chloride) The effectiveness of the tested alkyl diol dibenzoate compounds was assessed as a combination of the various reported material properties.
- Are alkyl diol dibenzoate compounds effective in plasticizing PVC?
- The effectiveness of the tested alkyl diol dibenzoate compounds was assessed as a combination of the various reported material properties. Of the four compounds tested in this study, 1,3-PrDB, 1,5-PDB, and 1,6-HDB (Figure 2) proved to be as effective in plasticizing PVC as the widely- and commercially-used plasticizer DEHP in blends at 40 phr.
- Is 1,5-pentanediol dibenzoate a PVC plasticizer?
- In a previous study, 1,5-pentanediol dibenzoate (1,5-PDB, see Figure 2) has been proposed and tested as a PVC plasticizer, since the only difference between 1,5-PDB and DEGDB lies within the diol linker part: the oxygen atom of the ether bond in DEGDB is replaced with a carbon atom in 1,5-PDB.
- Can 1,4-butanediol dibenzoate be used as a plasticizer?
- Further, while 1,4-butanediol dibenzoate is not a good candidate for a drop-in replacement of DEHP, due to its observed material hardening, this study suggests its use as a reversible heat-activated plasticizer or processing aid, with excellent plasticizer properties at mildly elevated temperatures.
- Are diol dibenzoates safe?
- The results were compared to blends of PVC/di (2-ethylhexyl) phthalate (DEHP), the most commonly used commercial plasticizer. DEHP has come under scrutiny, due to its suspected endocrine-disrupting behaviour, and the proposed diol dibenzoates have previously been shown to have the potential to be green, safe candidates for DEHP replacement.
