PERP Program Developments in Non-Phthalate Plasticizers
PERP Program Developments in Non-Phthalate Plasticizers Introduction In its broadest definition, a plasticizer is a material that when added to another yields a mixture which is easier to handle or has greater utility. Using water to soften clay or oil to plasticize pitch for waterproofing boats are both examples of early plasticized systems.
Diverging trends of plasticizers (phthalates and non
This was accompanied by their substitution with high molecular weight (HMW) phthalates and non-phthalates. HMW phthalates increased from 19% of the ∑plasticizer concentration to 46% between the mid-2000s and the late 2010s in house dust, and from 50% to 63% in SPM samples.
Non-phthalate plasticizer gives flexible PVC an environmental
Perstorp, a leading supplier of polyols, is launching a new renewable-based polyol ester (non-phthalate) plasticizer Pevalen Pro. It will reportedly make flexible PVC an even more attractive choice of plastic, based on a significantly lower carbon footprint versus competing materials and technologies. With 40% renewable content, Pevalen Pro not
Health, Eco Concerns Give Non-Phthalate Plasticizers a Push
Pevalen is a polyolester plasticizer that has four chains attached to a penta core—structurally more similar to citrates than phthalates, which have two chains attached to a central phthalate core, according to Perstorp’s Anders Magnusson, technical market development manager. This general-purpose non-phthalate boasts high efficiency and
Phthalates, non-phthalate plasticizers and bisphenols
The most abundant plasticizers in preschool dust were the phthalates di-isononyl phthalate (DiNP) and di-(2-ethylhexyl) phthalate (DEHP) with geometric mean levels of 450 and 266 μg/g dust, respectively, and the non-phthalate plasticizers bis(2-ethylhexyl) terephthalate (DEHT) and diisononylcyclohexane-1,2-dicarboxylate (DiNCH) found at 105
- How are nonphthalate and phthalate plasticizers determined?
- Nonphthalate and phthalate plasticizers were determined using an ultraperformance liquid chromatograph (UPLC) coupled to a 5500 Q Trap triple quadrupole mass spectrometer and operated in the positive electrospray ionization (ESI) mode (AB Sciex, Toronto, Canada).
- Are plasticizers phthalate or non phthalates?
- Plasticizers are usually grouped into phthalates and non-phthalates. Phthalates still represent the majority in the European plasticizer market, at around 60% . However, since the end of the 1990s there has been a steady shift within the phthalate plasticizers from LMW phthalates toward HMW phthalates .
- Are there phthalates and non-phthalate plasticizers in the coastal environment of Korea?
- Conclusions This is the first nation-wide survey of phthalates and non-phthalate plasticizers in the coastal environment of Korea. Phthalates and alternative plasticizers were detected in all sediment samples from the coastal zone of Korea. DEHP and DEHT were the dominant phthalates and NPPs, respectively.
- Are phthalate plasticizers contaminating the environment?
- DEHA and DEHT were detected in almost all sediment samples (detection rate: 98%), also suggesting major contamination by non-phthalate plasticizers. The occurrence of phthalates in the environment is related to production and consumption in industrial markets ( Gao and Wen, 2016 ).
- What phthalates are used in plasticizers?
- Plasticizers—particularly phthalates (PAEs), like di- (2ethylhexyl) phthalate (DEHP), di- iso -nonyl phthalate (DiNP), and di- n -butyl phthalate (DBP) are the most prevalent industrial chemicals applied to consumer products to increase flexibility, transparency, durability and lifespan , .
- Which phthalates dominate the plasticizer pattern in SPM samples?
- In contrast to house dust samples, the plasticizer pattern in SPM samples from mid-2010s is still very much dominated by phthalates (2017, 91% of the ∑plasticizer concentration). We identified emerging non-phthalates, TOTM, DEHT and DINCH, each with 2–3.5% of the total content.
