A Viable and Sustainable Alternative to Dioctyl Sebacate
While dioctyl sebacate (di (2-ethylhexyl) sebacate, or DOS) is a widely used plasticizer, it has become more challenging for companies to acquire sebacic acid-based plasticizers like DOS due to increasing costs, along with the uncertainty and lack of stable supply of sebacic acid.
Plasticizers: Types, Uses, Classification, Selection & Regulation
Most commonly used phthalate plasticizers include: DEHP: Low molecular weight ortho-phthalate. Still the world’s most widely used PVC plasticizer DINP, DIDP: High molecular weight ortho-phthalates Aliphatic dibasic acid Esters – These include chemicals such as glutarates, adipates, azelates and sebacates.
Long- and short-term stability of plasticized poly(lactic
Addition of plasticizers (regardless of plasticizer type) to the PLA, even at lower loading levels (5 wt%), decreased the yield strength and modulus of PLA. It is known that plasticizers result in a decrease in the intermolecular forces between the polymer chains, which lowers the polymer chain cohesion . Yield strength and the modulus of PLA
Plasticizers in Paint & Coatings: Uses, Types and Selection
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: Good stability to heat and ultraviolet light; Broad range of compatibility, and
Natural-based plasticizers and biopolymer films: A review
Besides, considering the plasticization efficiency and storage stability for chitosan films, GLY and PEG showed to be more suitable than EG and PG. Furthermore, a plasticizer concentration of 20% (w/w) with GLY or PEG was sufficient to obtain flexible chitosan film, exhibiting good stability for 5 months of storage.
- 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.
