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 in...
Dioctyl sebacate
Dioctyl sebacate (also di (2-ethylhexyl) sebacate, commonly abbreviated as DOS, DEHS, and BEHS) is an organic compound which is the diester of sebacic acid and 2-ethylhexanol . It is an oily colorless liquid and is used as a plasticizer, including in the explosive C4. [3]
Dioctyl Sebacate (DOS) - Chemical Supplier Distributor Chemceed
Application. Dioctyl Sebacate (DOS) is used as a plasticizer for PVC, nitrocelluloses, styrene resins, and synthetic rubbers where low temperature performance is required. DOS is also compliant with FDA CFR 21 for food contact materials. Dioctyl Sebacate can also be used in lubricants to allow more mobility at lower temperatures.
DOS (DEHS) Plasticizer - rpch.ru
Polyvinyl chloride compositions, which contain dioctyl sebacate have much higher abrasion resistance that those plasticized with monomeric plasticizers. The DOS plasticizer pour point is equal to -60°C. Sebacic acid and phthalic acid esters boiling points: DOS - boiling point=249°C at 4 mm. of the mercury column DBS - boiling point =344°C at
dioctyl sebacate(plasticizer)-source quality dioctyl sebacate
Bis (2-ethylhexyl) sebacate, or dioctyl sebacate (DOS), is a non-polar plasticizer that has two ester groups that bond with cationic compounds. It is mainly used in the formation of thin plasticized polyvinyl chloride (PVC) based membranes. Application Send Inquiry Dioctyl sebacate (DOS) 122-62-3 | BuyChemJapan
- 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.
