Rubber process oil is produced by Crude oil distillation process obtained from the composition and chemical interactions and isolation material extracted called Raffinate which has a kinematic viscosity at 100 °C of from 25 to 50 CST and which contains less than 3% oil.
- Aromatic Oils
- The primary characteristics of aromatic Hydrocarbons are the presence of the double bonded mix ring carbon structure. Aromatic extender oil well-known according to its viscosity which meets ASTM D-445 and Kinematic viscosity of transparent and opaque liquids it has different grades famous as high(heavy), medium, low (light) viscosity, TDAE, MES, and DAE.
- Paraffinic Oils
- This category of hydrocarbons constitutes branched chain or straight linked hydrocarbon molecules of various viscosities. Because the chain length will increase, the viscosity will increase, and also the rubber process oil becomes a lot of viscous. They find extensive usage in ethylene-propylene rubbers.
- Naphthenic Oil
- Naphtha is a category of hydrocarbons conjointly referred to as ‘cycloparaffins’. Although their structure is similar to the aromatic ring, these are single bonded so having a stable structure.
Rubber materials are wide employed in human life. Rubbers, each artificial and natural are commercially used to manufacture product from rubber bands to a toy to the enormous tyres for varied vehicles together with aircrafts. Most typical usage is especially on tires, automotive provide trade, white product, constructions, textiles and medicine applications. The most parts of rubber compounds are rubber, reinforcing fillers, method oils and oil based mostly softeners. Alternative additives, like stabilizers, antioxidants, processing agents are enclosed in less quantity. Mineral oils with completely different compositions (paraffinic, naphthenic and aromatic) have been evidenced their importance as softeners and extender method oils in rubber compounds and are used for over 100 years.
