  • What is a high volatility plasticizer?
  • ASTM D2288). Polymer processing equipment always operates at high tempera-tu es ( 150 C). Under these ditions, a>high volatility plasticizer changes from the liq-uid to the vapor phase generating losses in the process, hazardous environments for the workers, and machi ery fouling.Volumetric resistivity (ASTM D1169
  • Which type of plasticizer has increased its market share?
  • razel 2004).Another type of plasticizers that has increased its market share is terephthalic acid esters. Chem-ically, the only difference between them and orthophthalates (“traditional phtha
  • What are the characteristics of plasticizers market?
  • ed MaterialsAs mentioned above, plasticizers market is directly linked to the polymer market and partic-u arly to PVC. Therefore, properties of plasticized products presented in the following are typical of PVC pplications:Abrasion ASTM D5963). It is used in appli-cations where the material undergoes friction continuously, like
  • What is internal plasticization?
  • separation. This effect is known as internal plasticization and, although it gener-ates materials with outstanding performances, is not widely used due to the high costs of plasti-cizers ( ypych 2012). Additionally, the homogeneity of the material requires strict control of the polymeriza
  • Which plasticizer method is most used in industry?
  • d materials. For this reason and mainly for the relatively low cost of plasticizers, external plasticization is the method most used in industry. The plasticizer-polymer ratio in a plasticized product is expressed in parts of plasticizer per hundred parts of p
  • Why is plasticizer loss a problem?
  • processing.Volatility ASTM D1203). In some applica-tions products are exposed to high tempera-tures that can generate loss of plasticizer by aporization. In other cases, although temper-ature is low, exposition ime is long. As a consequence plasticizer must have low volatil-ity. In these cases, as plasticizer loss increases, the material bec
