  • Are plasticizers considered softeners?
  • Plasticizers are often referred to as softeners. In the 1920’s, researchers discovered that many esters of the polycarboxylic acid group, such as phthalic acid and phosphoric acid, were able to react with high polymers to form a homogeneous physical compound.
  • 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.
  • How do plasticizers affect tensile strength?
  • Plasticizers increase flexibility by lowering the glass transition temperature of polymers, decrease tensile strength but increase elongation and change the thermal properties so that the polymer is more easily worked by heat and perform better at low temperatures . What are the Different Types of Plasticizers?
  • How effective is a low polarity plasticizer?
  • Although the effectiveness varies among different plasticizer chemistries. The improved low-temperature flexibility depresses the glass transition temperature (Tg) of the polymer. Low-polarity plasticizers without aromatic moieties provide more rotational freedom vs. their higher-polarity counterparts of similar molecular weights.
  • Why are plasticizers important?
  • Well-chosen plasticizers can also improve resistance to UV exposure and chemical attack. This contributes to the long-term stability of the polymer. In specific applications, plasticizers can influence the dielectric properties of polymers. This makes them suitable for use in electrical insulating materials.
  • Why does plasticizer efficiency increase in PVC?
  • In a specific group of esters sharing a common acid group, the plasticizer efficiency rises when the molecular weight of the plasticizer decreases in PVC. Additionally, enhanced plasticizer efficiency is observed with a more linear alcohol chain. Incorporating a plasticizer into a PVC product extends the lower limit of its useful temperature range.
