  • 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.
  • Why is DEHP used as a plasticizer?
  • Due to its low cost and generally good performance, DEHP is widely employed as a plasticizer in manufacturing articles made of PVC. Melting point: −50°C Boiling point: 250 - 257°C at 0.5 kPa DEHP offers good gelling, satisfactory electrical properties and helps to produce highly elastic compounds with reasonable cold strength.
  • 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.
  • Can DEHP be used in food packaging?
  • It cannot be used in most products. It extracts readily into non-polar solvents (oils and fats in foods packed in PVC). Therefore, the US Food and Drug Administration (FDA) permits the use of DEHP-containing packaging only for foods that predominantly consist of water. DEHP is used in applications, such as:
  • Which terephthalate is a good replacement for DEHP?
  • Terephthalate esters, particularly di-2-ethylhexyl terephthalate, are the most popular replacements for DEHP. They are less compatible with PVC. But their low cost and long history as commercial plasticizers are their most attractive features. Dialkyl terephthalates with sidechains containing:
  • Are dibenzoate plasticizers better than phthalate?
  • Dibenzoate plasticizers are valued primarily for their strong solvency. But they are defensive against phthalate plasticizers. This is because of reduced low-temperature flexibility and poor plastisol viscosity characteristics. Both plasticizers are often used in blends with other plasticizers. Benzoates also act as processing aids.
