Rubber Process Oils can be broadly divided into 1.Aromatic types 2. Naphthenic types 3. Paraffinic
Rubbers both synthetic and natural, are commercially used to convert into the final products, from a toy to the tyre of a vehicle.
Rubber Process Oils are used during the processing and production of rubber compounds. These help in improving the dispersion of fillers and flow characteristics of the compound during further processing.
Depending on the type of rubber and the end product applications, various types of rubber process oils are selected.
The range of IPOL Rubber Process Oils can be broadly divided into 1.Aromatic types 2. Naphthenic types 3. Paraffinic types which we can supply only Aromatic one.
AROMATIC OILS
The primary characteristics of aromatic hydrocarbons is the presence of the double bonded mix ring carbon structure. Aromatic extracts procured from selected refineries and suitably blended to meet stringent specifi cations, are used for compounding batches to manufacture Tyres, Tubes, Hoses, Calendar sheets, etc. Typical inspections of some of the IPOL Aromatic Grades are as follows –
