Effects of UV-based oxidation processes on the degradation
The highest concentrations of THMs, HAAs and HALs reached 61.8 ± 4.9 μg/L, 40.5 ± 3.1 μg/L and 17.3 ± 2.6 μg/L, respectively. As for the DBP yields (μg-DBPs/mg-DOC), The yields of THMs and HAAs from PET-derived DOM (Figure S12) were higher than those from PA6-derived DOM, but were all lower than those from surface water (Du et al., 2025).
Dibutyl phthalate
Dibutyl phthalate (DBP) is an organic compound which is commonly used as a plasticizer because of its low toxicity and wide liquid range. With the chemical formula C 6 H 4 (CO 2 C 4 H 9 ) 2 , it is a colorless oil, although commercial samples are often yellow.
use of special carbon blacks to gain unique properties and
Higher DBP number leads to higher viscosity, higher hardness, higher modulus, and higher electrical conductivity. Higher DBP numbers also mean a better dispersing black and a reduction in calendar and extruder swell. High structure blacks are known for their good extrusion properties like low nerve, smooth surfaces, with sharp corners and edges.
plasticizer dbp and dop dibutyl phthalate for rubber pvc
DBP is the most commonly used plasticizer of PVC, which can make products have good softness. DBP is an excellent plasticizer for nitrocellulose, with strong gelation ability.Stability, flexural resistance, adhesion and water resistance are better than other plasticizers. .plasticizer dbp and dop dibutyl phthalate for rubber pvc .

- Is DBP used in polychloroprene rubber?
- The Risk Assessment for DBP (ECB, 2004) specifies that DBP is used in some polychloroprene rubber and nitrile rubber, but not in all polychloroprene (neoprene) or nitrile rubbers. New information on actual uses is not available. DBP is used extensively in the adhesives industry to plasticise polyvinyl acetate (PVA) emulsions.
- What are the uses of DBP adhesives?
- According to the Risk Assessment for DBP (ECB, 2004) the most important uses of the adhesives are for paper and packaging, wood building and automobile industry. Epoxy resins. Probably same application that in the Risk Assessment for DBP (ECB, 2004) is mentioned as "solvent in the production of fiber glass".
- What is DBP used for?
- DBP is used as a softening agent and lubricant in the textile industry, particularly in the production of synthetic fibers, fabrics, and yarns. It improves the flexibility, drapability, and processing characteristics of textile materials, making them suitable for apparel, upholstery, and other textile applications.
- Is DBP still used in printing inks?
- One application described in the confidential part of the ECHA report. According to CEPE (European Council of producers and importers of paints, printing inks and artists’ colours), DEHP, BBP and DBP are no longer used in printing inks by CEPE/EuPIA (European Printing Ink Association) members following its classification as reprotoxic.

- What is DIDP in flexible PVC?
- The typical content of DIDP in flexible PVC products is between 25 and 50% (w/w). It has properties of volatility resistance, heat stability and electric insulation and is typically used as a plasticiser for heat-resistant electrical cords, leather for car interiors, and PVC flooring (ECPI, 2009).
