Rubber Process Oils can be broadly classified into three basic groups depending on the physical arrangement of the carbon atoms namely , parafinics , napthenics 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.

Predominantly paraffinic rubber process oils suitable for use as plasticisers

Elasto 165 and 255 are highly paraffinic.

Application Areas :

Elasto 165 is suitable for use in epdm rubbers. elasto 245 is particulary suitable for use in butyl and ehtylene propylene rubbers and light coloured rubbers.

Elasto 255 is specially developed for shoe sole applications.
