  • 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) .
  • Which plasticizer reduces tensile strength?
  • As the plasticizer concentration increased from 20% to 40%, Gly-plasticized films exhibited the highest reduction value of 39% (decreased to 3.66 MPa) in tensile strength followed by PG-plasticized films with reduction value of 19% (dropped to 6.90 MPa).
  • Are polar plasticizers compatible with polar polymers?
  • Lower Mw plasticizers have a noticeable plasticization effect than their higher counterparts. Good compatibility requires matching polar plasticizers with polymers that have polar groups. The distance of the polymer's polar groups also influences the plasticizer polarity needed.
  • Are biopolymers a good substitute for conventional plasticizers?
  • The use of natural and/or biodegradable plasticizers, with low toxicity and good compatibility with several plastics, resins, rubber and elastomers in substitution of conventional plasticizers, such as phthalates and other synthetic conventional plasticizers attracted the market along with the increasing worldwide trend towards use of biopolymers.
  • What is the tensile strength of plasticizers?
  • The presence of plasticizers at a low concentration of 20% demonstrated high tensile strength value of 6.01, 5.11, 8.51 and 6.24 MPa for Gly-plasticized, Sor-plasticized, PG-plasticized and PEG-plasticized films, respectively. Without any plasticizer (blank), a brittle film with a low tensile strength value of 2.49 MPa was obtained.
