Dibutyl Phthalate - an overview | ScienceDirect Topics
The maximum DEHP level for drinking water is determined by US EPA as 0.006 mg l 1, based on reproductive difficulties, liver problems, and increased risk of cancer in adult animals. Oral intermediate exposure for DEHP is 0.1 mg kg 1 day 1, based on reproductive effects in adult animals.
Rubber Processing: Mix Process and End Product Properties
Rubber Processing: Effects of the Mixing Process on Product Properties. At Goodyear, we consider the manufacture / mixing of custom compounds a core competency and big value addition for our customers. In many cases, end product rejects and defects can be attributed to inadequate mixing quality not recognized during quality control in the
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.
3 Identified alternatives to DEHP, DBP and BBP
Notably DBP were found in 30% of the samples in 2004. The percentage had decreased to about 10% in 2007 and further to 1% in 2008 (FCPSA 2008b). BBP is found in only a few percentages of the samples all the year.
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?
- The low viscosity and compatibility of DBP make it suited for PVA-based adhesives for bonding cellulosic materials. 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.
- 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.
- Why is the use of DBP increasing?
- The increase in the use of DBP from a level below 1 tonnes/year in 2000-2005 to 11 tonnes in 2006 may be due to an error in the registration. The declaration of the substances to the product register is mandatory for preparations containing one or more substances listed in Annex I to Directive 67/548/EEC (now Annex VI to Regulation 1272/2008) .
- 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).
