RPO is normally classified in three basic types depending upon the presence of Carbon atom, namely Aromatic, Paraffinic & Naphthenic Oil.
Aromatic Oils are generally dark in colour & good compatible with most Rubber Polymers. It is extensively used in the manufacturing of Automobile Tyres, Tread Rubber, Conveyor Belts, Automotive Components & Floor Mats etc., where colour of the end product is not important.
Paraffinic Oils are generally light in colour having wide viscosity range, higher Aniline &Flash Point. It is extensively used in the manufacturing of butyl tubes, EPDM based rubber products, such as profiles, hose pipe& automotive Components.
Naphthenic oil has good colour stability, solubility & thermal stability. It is extensively used in the manufacturing of foot wear, LPG tubes, hot water bags, moulded & extruded products. It may be used as banbury lubricants in Rubber Industries.
Low PCA Oils
A new generation oils meeting EU requirement. It is MES type of oil having PCA less than 3% as per IP 346.
