  • What are plasticizers used for?
  • Introduction Plasticizers are an important class of low molecular weight non-volatile compounds that are widely used in polymer industries as additives . The primary role of such substances is to improve the flexibility and processability of polymers by lowering the second order transition temperature, the glass transition temperature (Tg).
  • What are natural based plasticizers?
  • Nowadays, there is increasing interest in the use of natural-based plasticizers that are characterized by low toxicity and low migration. This group includes epoxidized triglyceride vegetable oils from soybean oil, linseed oil, castor-oil, sunflower oil, and fatty acid esters (FAEs) .
  • What are the different types of plasticizers?
  • Industrially, the most common plasticized polymers are PVC, poly (vinyl butyral) (PVB), poly (vinyl acetate) (PVAc), acrylics, cellulose molding compounds, nylon, polyamides and certain copolyamides. PVC processing is by far the most important use of plasticizers, consuming over 80% of production , .
  • Which polymers are plasticized?
  • The plasticizers produced have been applied in 60 polymers and more than 30 groups of products. Industrially, the most common plasticized polymers are PVC, poly (vinyl butyral) (PVB), poly (vinyl acetate) (PVAc), acrylics, cellulose molding compounds, nylon, polyamides and certain copolyamides.
  • How do plasticizers affect processing?
  • Plasticizers can influence processing by inducing lower viscosity, faster filler incorporation, easier dispersion, lower power demand and less heat generation during processing, better flow, improved release and enhanced building tack.
  • What are the characteristics and performance of plasticizers?
  • Attributes and performance of plasticizers Plasticizers are, in general, high boiling point liquids with average molecular weights of between 300 and 600, and linear or cyclic carbon chains (14–40 carbons) , .
