  • What are plasticizers & stabilizers?
  • Plasticizers are one of the key materials which improve the characteristics of the final products such as flexibility, which would not be realized without it, to PVC and rubbers. PVC stabilizers are one of the essential materials for PVC to improve processability and characteristics of PVC products.
  • What are the most popular plasticizers for PVC?
  • There is a vast array of Primary plasticizers for PVC. This discussion will be limited to the most popular, the Phthalate Esters. Phthalic acid is reacted with various alchohols to manufacture a family of Phthalate plasticizers of which Di Octyl Pthalate (DOP) is the most popular.
  • What are PVC stabilizers?
  • PVC stabilizers are one of the essential materials for PVC to improve processability and characteristics of PVC products. We are focusing on the research of PVC stabilizers that meet global regulations of chemical materials. Plasticizers give useful properties such as flexibility to PVC and rubbers.
  • How to modify the structure of PVC particles?
  • The structure of the PVC particles can be modified by selecting suitable suspending agents and Polymerisation Catalyst. Less porous types are extensively used for the high volume Rigid or Unplasticised PVC applications like PVC Pipes, Windows, Sidings, Ductings.
  • Can a primary plasticiser be absorbed into PVC resin?
  • Primary plasticizers have good compatibility with PVC resin and can be absorbed in large quantities. In special cases as much as 140-150 PHR of Primary plasticiser can be gelated into PVC for super soft products. Nearly all Plasticisers are liquids and have to be absorbed in Suspension resin in heated mixers.
  • Why is DBP a good plasticiser?
  • DBP tends to evaporate out slowly with use, thereby stiffening the product, i.e. its permanency is low. The higher Carbon atoms Phthalates have better permanence. They do not volatilize easily at high temperatures. If a Plasticiser volatilizes the product becomes harder and brittle. Fusing and gelation take longer with DNP & DIDP.
