  • 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.
  • What is PVC slurry used for?
  • PVC slurry in plasticizers and additives are used in processes like rotational casting and coating to produce inflatable products and rexine or in artificial leather manufacturing. What is the chemical nature of plasticizers? An effective plasticizer molecule for PVC has two types of structural components: Non-polar component.
  • Which PVC resin is used for plastisols and Organosols?
  • Therefore, K-67 Suspension PVC resins are used for soft PVC products and K-70 or K-73 suspension PVC resins are used for very soft PVC products. On the other hand, for plastisols and organosols, emulsion and micro-suspension grade PVC is used.
  • Which PVC resin is used for soft PVC products?
  • Thus, the more the plasticizer requirement, the higher the K value of resin used, as porosity increases with the K value. Therefore, K-67 Suspension PVC resins are used for soft PVC products and K-70 or K-73 suspension PVC resins are used for very soft PVC products.
  • 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.
  • Why do plasticizers have a higher K value?
  • 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. Thus, the more the plasticizer requirement, the higher the K value of resin used, as porosity increases with the K value.
