Rubber oils can be broadly classified in to three basic groups depending on the physical arrangement of the carbon atoms namely, Paraffinic, Naphthenics and Aromatics. All petroleum oils are mixtures of various hydrocarbon groups and their classification is arbitrary, and is based on the predominance of a particular hydrocarbon group.
RUBBER OIL 1165
This is a highly paraffinic medium viscosity type of oil specially developed for use as plasticiser in the manufacture of EPDM rubbers. The oil also possesses good resistance to evaporation loss.
RUBBER OIL 1245
It is a light coloured paraffinic type of oil and has good colour stability. It is also has high flash point and good high temperature properties, but it has low solvency.lt finds greatest use in butyl and ethylene propylene rubber. It is recommended to use for the processing of light coloured rubber goods such as white walled tyres, Shoe soles, toys, sporting goods, etc.

RUBBER OIL 1255
This is a highly paraffinic type of oil specially developed for compounding purpose of shoe sole application. The oil has moderate solvency power with low evaporation loss.
RUBBER OIL 1541
This is a naphthenic type of oil and iias fairly good colour stability with adequate high temperature properties. Its solvency is better than RUBBER OIL 1245/1255, and is suitable as general-purpose rubber oil for mats, footwear moulded and extruded goods.
RUBBER OIL 1590
This is a naphthenic type of oil, specifically developed to meet the requirement of the major tyres manufacturer; the product is used to make the fabric-coating compound, used in coating nylon tyres cords of passenger vehicle tyres. Petroleum Oils are used in the manufacture of virtually all rubber products such as tyres, tubes, battery cases, footwear, mats, hoses etc. They are the keystones from the raw material stage to the finished products. Rubber oils are added to the polymer that may or may not have been oil extended. They perform the following functions.
• Facilitate mixing operation
• Reduce compounding time
• Improve possibility
• Modify physical properties of the finished product
• Minimise power consumption
• Reduce cost of finished goods.
RUBBER OIL 0710
This is an aromatic type of oil and due to the presence of double bonds It is the least stable compared to RUBBER OIL 1245 and RUBBER OIL 1541. It is dark in colour and has good solvency making it compatible with most rubber polymers. It finds extensive use in the manufacture of automobile tyres, belting, battery cases etc, where colour is not an important factor. RUBBER OIL 0715 It is also aromatic process oil with higher viscosity and is specifically developed for use as extender oil in the manufacture of Styrene Butadiene Rubber.
