Viscosity Modifier


Petadd VM-43(C) is a pellet-form, olefin copolymer (OCP). It is an excellent choice when looking to increase viscosity in mineral oil based lubricants, whilst also providing excellent low temperature properties.


  • Use as an additive to increase and maintain viscosity in lubricants.
  • The recommended treat rate is 6 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.
  • Easy and quick to use (fast dissolving pellet).
  • Highly stable (polymer product).
  • Excellent thickening power.
  • Excellent low temperature properties.
