Sunoco Sunpar oils are highly refined, premium quality oils. Structurally, they have a predominance of saturated rings and long paraffinic side chains. They are dewaxed to low pour points and are available in a wide range of viscosities.
Sunoco Sunthene oils are manufactured from select wax-free naphthenic crudes to provide optimum colour and colour stability while still maintaining good compatibility and processing characteristics. This is achieved by selective refining to remove colour-producing impurities without appreciably changing the aromatic content of the naphthenic oil.
These are severely treated naphthenic process oils which require no precautionary labelling according to the new OSHA and 83/467/EEG regulations on the labelling of substances having possible carcinogenic hazards.
