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. [3] Production and use [ edit]
Plasticizers in Paint & Coatings: Uses, Types and Selection
Phthalate-based Plasticizers Di-n-octyl phthalate (DOP) DOP or DnOP is light-colored, low volatility & odorless liquid. It was the most commonly used all-purpose plasticizer, although mainly used for polyvinyl chloride (PVC) resins. It is insoluble in water & has a low viscosity of 56 mPa.s at 25°C. DOP features:
Infrared spectral changes in PVC and plasticized PVC during
Abstract. The behaviour of PVC and PVC plastisols has been studied during their thermal treatment using an in situ FTIR technique. The plasticizer introduces certain modifications in the spectrum of the resin which are more marked in the case of the more compatible plasticizers. The A 1427 A 1435 and A 637 A 616 ratios of the intensities of the
DIOCTYL PHTHALATE (DOP)
DOP (Di-sec-Octylphthalate) is the most widely used general purpose plasticizer for the manufacture of flexible plastics (especially with PVC). It is insoluble in water and has a good stability to heat and ultraviolet light, a broad range of compatibility, and excellent resistance to hydrolysis. It is used in PVC, polyvinyl acetate, rubbers
PVC Plasticizer DOP DBP Substitute EFAME J107
2. Light yellow color, dioctyl phthalate(DOP) Substitute. 3. Low volatility and little mobility. 4. Good compatibility with PVC resin. 5. Won't react in heat or light. 6. Meet SGS and U. S. FDA standards. 7. It can substitute part of DOP or DBP, in the making of PVC soft products.
- Is DOP a good plasticizer?
- Plasticizing efficiency of DOP is considered as “1” and efficiency all other plasticizers is evaluated with reference to DOP. Besides, cost of DOP based compound can be reduced by blending it with CPW of appropriate grade in appropriate proportion (70:30), without affecting quality of product. However, DOP is on its way out due to health concerns.
- Which plasticizer is better DOP or PVC?
- The studies showed that only a PVC blend with HEPCL 8 performed better than DOP in terms of mechanical properties, and at the same time exhibited the highest migration resistance. 2.1.3. Other Branched and Hyperbranched Plasticizers
- Can polymeric plasticizer polyisobutene (PIB) be substituted for DOP plasticizer (50phr)?
- 4. CONCLUSIONS A polymeric plasticizer polyisobutene (PIB) dissolved in a solvent carboxylic acid Bis (2-ethylhexyl) cyclohexane1,2-dicarboxylate (DOCH) was used in substitution to DOP plasticizer (50PHR) were add to PVC resin and their properties evaluated.
- Are oleic acid based plasticizers better than phthalate plasticizer?
- Besides, new plasticizers presented a lower viscosity than DOP, which is very important in PVC plastics production. Furthermore, the thermal stability of PVC blended with MDA or EDA was higher than for DOP, so the studied oleic acid-based plasticizers could serve as a promising alternative to phthalate plasticizers.
- Does DOP elongation increase the tensile strength of PVC films?
- Elongation at break values of PVC films with DOP and different hyperbranched plasticizers were comparable and the tensile strength was slightly higher for new plasticizers than for DOP. The new compounds were characterized with a good thermal stability and improved plasticizer migration resistance.
- Which plasticizer is used for PVC?
- The most common industrial plasticizers, called phthalates are used in various consumer product applications. Dioctyl phthalate (DOP) is a plasticizer used specifically for PVC, having a great cost-benefit ratio and excellent properties for general applications .
