Viscosity Modifier


Petadd VM-47(C) is a pellet-form, olefin copolymer (OCP), it is an excellent choice when looking to significantly increase viscosity in base oil lubricants, whilst also providing a moderate degree of shear stability.


  • Use as an additive to increase and maintain viscosity in lubricants.
  • The recommended treat rate is 3 to 10%, (depending on base oil used, and the required viscosity).
  • Dissolve completely in base oil (under high agitation at ~110°C for 8 hours).


  • Easy to handle (available in a variety of pack sizes*).
  • Easy and quick to use (fast dissolving pellet).
  • Highly stable (polymer product).
  • Excellent thickening power.
