Rubber Process Oil (RPO) has a key role as lubricants. Firstly, it improves the quality of rubber blending, Secondly, it facilitates the embodiment of fillers and other additives.

Notably, RPO has a lot of applications. surprisingly, about 2/3 of the rubber industry is involving in the tire industry, however, 1/3 being non-tire related which is involved in:

  • Hoses
  • Conveyor belts
  • Adhesives & Sealants
  • Consumer Products
  • Paints & Coatings
  • Pharmaceuticals
  • Polymers
  • Transmission belts
  • Seals and gaskets

Various kinds of rubber process oil are producing depends on the kind of rubber and also the end uses.
