  • 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.
  • 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.
  • Are plasticisers compatible with PVC?
  • Importantly, plasticisers are not just additives (like pigments or fillers): they are major components that determine the physical properties of polymer products. They are compatible with PVC, have the desired plasticizing efficiency that makes PVC soft and do not easily migrate into air or water.
  • What happens when plasticizers are added to PVC?
  • This widens the distances between the molecules, and results in the softening of the PVC resin When plasticizers are added to PVC at this stage, the plasticiser molecules place themselves between the distanced PVC molecules, preventing the PVC molecules from returning closer together at a normal temperature.
  • What is plasticising PVC?
  • The softness of the material is therefore maintained. Such a process is called plasticising. In Europe, about 30 % of the total PVC resin production is used for flexible PVC products. The process of plasticising PVC can make the material harder or softer. Before being made into products, PVC is still just a resin, or powder.
  • 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.
