  • 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 polymers use plasticizers?
  • Other polymer systems that use small amounts of plasticizers include polyvinyl butyral, acrylic polymers, poly (vinyldiene chloride), nylon, polyolefins, and certain fluoroplastics. Plasticizers can be used with rubber, although more often these materials fall under the definition of extenders, rather than plasticizers.
  • 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 , .
  • Can PVC be used as primary plasticizer?
  • PVC. However, the results showed partial miscibility feature with PVC. On the contrary, after epoxidation of t he esterified compound s howed good miscibility with PVC. cardanol cold be use as primary plasticizer . Table 2 Soyabean oil. plasticizer.

  • What are plasticizer characteristics?
  • Plasticizer characteristics determine not only the compatibility but also the amount which can be added to the polymer while ensuring the thermodynamic stability of the mixture. Thermodynamic stability means the absence of plasticizer exudation at temperature changes, mechanical stresses, and pressure.
  • Where do natural plasticizers come from?
  • Several natural plasticizers originate from agricultural products like trees, oleaginous plants, cereals, vegetables, and fruits, as well as their waste . Utilizing bio-based wastes as natural plasticizers, various polymers and materials have been tested.
