  • Are dibenzoate plasticizers good for flexible PVC?
  • viscosity depressing additives in flexible PVC. 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.
  • What are natural product type plasticizers?
  • Vegetable oil derivatives are the most widely used natural product type plasticizers. Products consisting of triglyceride esters of unsaturated fatty acids (e.g., soybean oil, linseed oil) in which the double bonds in the fatty acid residues have typically been epoxidized have been commercial products for decades.
  • Can phthalate plasticizers be used in Plasticized PVC?
  • For example, the use of phthalate plasticizers in plasticized PVC is neither prohibited in the US (federal and state legislation) nor the EU in any plasticized PVC product. We have already discussed recent regulatory status w.r.t phthalate plasticizers in child care articles. There are also federal regulations (not laws) for plasticizers.
  • Why are plasticizers used in polyvinyl chloride?
  • Plasticizers increase the flow and thermoplasticity of a polymer. This is done by decreasing the viscosity of the polymer melt, Tg, Tm, and elastic modulus of the finished product. During this process, the fundamental chemical character of the plasticized material remains unaltered. Plasticizers are most often used in Polyvinyl chloride.
  • Are terephthalate esters compatible with PVC?
  • 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. More than 8 carbon atoms have limited compatibility with PVC.
  • 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.
