Rheology of Green Plasticizer/Poly(vinyl chloride
Phthalate plasticizers such as di (2-ethylhexyl phthalate) (DEHP) are the most common PVC plasticizers and have recently been linked to a wide range of developmental and reproductive toxicities...
DOS (DEHS) Plasticizer - rpch.ru
All plasticizers shall meet the following common requirements: thermodynamic compatibility with a given polymeric material; low volatility; absence of odour, chemical resistance, resistance to fluid medium (e.g. oil), detergent or solvent extraction from the given polymeric material.
Plasticizers: Types, Uses, Classification, Selection & Regulation
Di-2-ethylhexyl-phthalate (DEHP, formula: C 6 H 4 (C 8 H 17 COO) 2) is a low molecular weight ortho-phthalate produced by esterification of phthalic anhydride with 2-ethyl-hexanol. It is non-volatile, colorless and odorless viscous liquid, soluble in oil, but not in water.

However, there is some confusion in the literature with DEHS and DOS used somewhat interchangeably (BIBRA, 1996). Therefore, both DEHS and DOS are included in this assessment. However, where the documentation specifically uses one name, that name is used, and data on DOS were not included if the results clearly referred to the straight chain
Plasticizer
Tools. Stray plasticizers migrating from a soft vinyl eraser have partially dissolved a plastic pen cap over the course of time. A plasticizer ( UK: plasticiser) is a substance that is added to a material to make it softer and more flexible, to increase its plasticity, to decrease its viscosity, and/or to decrease friction during its handling
- Is DOS a good plasticizer?
- DOS is a very useful plasticizer for organosols and plastisols. The viscosity of plastisols based on DOS as the sole plasticizer is approximately one-third that of comparable dioctyl phthalate systems. The initial viscosity advantage over dioctyl phthalate is retained, even on prolonged aging.
- When should a plastisol based on DOS be used?
- It should be used in minimal amounts that meet specific low-temperature performance requirements. DOS is a very useful plasticizer for organosols and plastisols. The viscosity of plastisols based on DOS as the sole plasticizer is approximately one-third that of comparable dioctyl phthalate systems.
- What is the viscosity of plastisol based on DOS?
- The viscosity of plastisols based on DOS as the sole plasticizer is approximately one-third that of comparable dioctyl phthalate systems. The initial viscosity advantage over dioctyl phthalate is retained, even on prolonged aging. DOS is used in several elastomers, such as polychloroprene, chlorinated polyethylene and chlorosulfonated polyethylene.
