RPO ( Rubber Processing Oil) About

Rubber Processing Oil (RPO) is a petroleum-derived hydrocarbon mixture used as an extender, softener, and internal lubricant in rubber manufacturing. It reduces compound viscosity, aids filler dispersion, lowers production costs, and enhances the physical flexibility and processability of both natural and synthetic rubber products

Chemically, RPO acts as a plasticizer. It inserts itself between polymer chains, lowering the internal friction and rigidity of raw rubber during mixing, milling, and extrusion. By making the mix softer and more fluid, RPO reduces the mechanical energy and electricity required by factory machinery. It also acts as a cost-effective extender, letting manufacturers increase batch volume without losing core structural integrity

Rubber Processing Oil (RPO) is a vital compounding ingredient derived from the vacuum distillation and refining of crude petroleum. During production, lighter fuel fractions are separated, leaving heavy, high-boiling hydrocarbon fractions.
