Rubber Process Oil (RPO)

Rubber Process oil is produced by Lub Cut. The crude oil distillation process is obtained material to lube cut. The companies named RPO lube cut with a solvent composition and the chemical interactions and isolation RPO extract (product of solvent extraction RPO) material extracted is called Raffinate.
This product is a fully rich aromatic by-product from the solvent extracting process to modify the physical properties of the vulcanization and to reduce the cost of the finished product.

The primary characteristics are the presence of the double bonded mix ring carbon structure. Aromatic extracts procured from refineries are suitably blended to meet stringent specifications with different Viscosity. Heavy RPO is also an aromatic process oil with higher viscosity and is specifically developed for use as extender oil in the manufacture of polystyrene butadiene rubber. This aromatic type of rubber process oil is dark in color and has good solvency. It is compatible with most rubber polymers and suitable for use in the manufacture of automobile rubber tires, belting, battery case, etc. where color is not an important parameter. Heavy RPO was specially developed for use in SBS rubber.
