  • 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.
  • What is a good plasticizer molecule for PVC?
  • An effective plasticizer molecule for PVC has two types of structural components: Non-polar component. The polar component of the molecule must be able to bind reversibly [not like vulcanized rubber] with the PVC polymer, thus softening the PVC.
  • 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.
  • How can plasticizers be used to make polymers soft and flexible?
  • By adding plasticizers to compatible polymers, the materials can be modified in such a way that they become soft and flexible by decreasing their glass transition temperature. Plasticizers are classified according to their molecular structure into monomeric or polymeric types.
  • What is a plasticizer in PVC?
  • A plasticizer reduces melt viscosity during processing. In PVC products, the glass transition temperature (Tg) and elastic modulus of PVC are also reduced. Liquids are usually called “plasticizers”, whereas solids like nitrile rubbers, compatible polyesters and some polyacrylates are called plastifiers or flexibilizers.
