  • What is a plasticizer & how does it work?
  • A plasticizer is a material that when added to another substance, makes that material softer or more flexible. Although this definition can include many products, from water added to clay for production of pottery to lime mixed with concrete to make it more workable, the word “plasticizer ” generally refers to materials used in plastics.
  • How does a plasticizer interact with a polymer?
  • External plasticizers have a low vapor pressure. They interact with the polymer at high temperatures without a chemical reaction. The interaction happens through their solvent or swelling ability. It's essential to differentiate between solvent plasticizers and nonsolvent plasticizers.
  • Why are plasticizers used in electrical insulating materials?
  • In specific applications, plasticizers can influence the dielectric properties of polymers. This makes them suitable for use in electrical insulating materials. Plasticizers can enhance compatibility between polymers and various additives or fillers. This results in more homogeneous and stable formulations.
  • What is a general purpose plasticizer (GP)?
  • There is another classification for external plasticizers from the commercial point of view. If a plasticizer imparts a desired flexibility, it has a good balance of other properties and, additionally, low cost, it is called general purpose plasticizer (GP).
  • Can plasticizers be used with rubber?
  • Plasticizers can be used with rubber, although more often these materials fall under the definition of extenders, rather than plasticizers. The 1998 estimated worldwide production of plasticizers approached 9 billion pounds. Over 85% of this volume were phthalic acid esters.
  • What is plasticizer efficiency?
  • Plasticizer efficiency is used to describe the ability of a plasticizer to make the product softer and is reported as a ratio of the slope of the hardness versus plasticized concentration to the slope of that found for DOP. The relationship of hardness and plasticizer concentration expressed in phr (parts per hundred resin) is shown in Figure 3.
