Rubber Process Oil (RPO) is a petroleum-derived hydrocarbon oil used as a key processing aid throughout the rubber manufacturing industry. Refined from crude oil, RPO is composed of a blend of paraffinic, naphthenic, and aromatic hydrocarbon compounds \u2014 and it’s the ratio of these three fractions that defines an oil’s character, performance, and best-fit application.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

Functionally, RPO works its way between the polymer chains of raw and compounded rubber, improving processability while simultaneously helping manufacturers reduce production costs. It is a foundational ingredient across a huge range of everyday rubber products \u2014 tires, hoses, footwear, conveyor belts, seals, and carbon black masterbatches, among others.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Because rubber compounds and end-use requirements vary so widely, no single oil type fits every application \u2014 which is why RPO is produced and supplied in distinct grades tailored to different rubber types and performance needs.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
