Rubber Process Oil (RPO) is a vital ingredient in the manufacturing of rubber products. It is used to improve the processability and enhance the physical properties of rubber compounds. RPO is categorized based on the type of base oil used – Aromatic, Naphthenic, or Paraffinic.
Aromatic Rubber Process Oil (RPO – Aromatic)
Naphthenic Rubber Process Oil (RPO – Naphthenic)
Paraffinic Rubber Process Oil (RPO – Paraffinic)
