  • Which plasticizer has a low plasticizing efficiency?
  • Polymeric plasticizer generally has low plasticizing efficiency. Navarro et al. 35 replaced the chlorine on the PVC backbone via nucleophilic substitution of thiol groups attached to the benzene ring of di (2-ethylhexyl)phthalate (also known as dioctyl phthalate, DOP, the most common plasticizer), to give totally nonleachable PVC.
  • Which PVC material is used in plasticizers?
  • Soft or flexible PVC products like extruded soft tubing, profiles and sheeting, thin calendared sheets, etc. make use of suspension-grade PVC. Since plasticizers are dissolved in SPVC (PVC is not dissolved in plasticizers) during the mixing process, the higher the porosity of PVC grain, the higher the rate of plasticizer absorption.
  • Can a 1:1 plasticizer be used for soft PVC products?
  • However, the system with 1:1 plasticizer over PVC had a Tg below 0 °C, indicating that the system was completely flexible at room temperature and could be used for soft (flexible) PVC products. Variation of glass temperature with content of DOP (black stars) and DOP-O-CP52 (red blocks).
  • What are the different types of PVC plasticizers?
  • 1. General purpose plasticizer [GP] - They provide the desired flexibility to PVC, overall balancing quality with a low cost. Examples are DIHP, DOP (DEHP), DINP and DIDP. They can be used along with secondary plasticizers to reduce the cost. DIDP evaporates 76% less than DOP.
  • What is an ideal plasticizer?
  • An ideal plasticizer should be: Primary plasticizers are low-volatility liquids, whose polarity is such that they are sufficiently compatible with PVC and will not be readily squeezed out of plasticized PVC by moderate pressure. They are mainly responsible for providing flexibility.
  • What is the difference between DOP-o-cp52 and PVC plasticizer?
  • Further increases in the ratio of plasticizer over PVC led to decreased plasticizing efficiency of DOP-O-CP52 compared to DOP. However, the system with 1:1 plasticizer over PVC had a Tg below 0 °C, indicating that the system was completely flexible at room temperature and could be used for soft (flexible) PVC products.
