RPO (Furfural Extract)
Rubbers, both synthetic and natural are commercially used to produce products from rubber bands to a toy to the giant tires for various vehicles including aircrafts.
Rubber Process Oils (Furfural Extract) are used during mixing of rubber compounds. These help in improving the dispersion of fillers and flow characteristics of the compound during further processing. Their main applications are;
· Rubber bumpers
· Industrial Hoses
· Wire and cable coating
· Shoes industry
· Flooring Material
The Global RPO standard categories (and respectively in PTG) are as follow;
Aromatic types: The primary characteristics of aromatic hydrocarbons are the presence of the double bonded mix ring carbon structure. Aromatic extracts procured from selected refineries and suitably blended to meet stringent specifications, are used for compounding batches to manufacture Tires, calendared and molded sheets, Tread rubber etc.
Naphthenic types : Naphthenic are a class of hydrocarbons also referred to as ‘cycloparaffins’. Though their structure is similar to the aromatic ring, these are single bonded thus having a stable structure. Several such hydrocarbon rings may be linked indicating a variety of available grades. Their unique color stability, solubility and good thermal stability makes them ideal for molded articles, slippers, LPG tubes, floor tiles, etc.
Paraffinic types: This class of hydrocarbons constitutes branched chain or straight linked hydrocarbon molecules of various viscosities. As the chain length increases, the viscosity increases and the rubber process oil becomes more viscous. They find extensive usage in EPDM, Butyl rubbers. IPOL grades include Paraffinic oils with high viscosity and high flash point for better shelf life of the end product. The high viscosity and high flash point IPOL paraffinic oils are extensively used in EPDM profiles for automotive applications.
