Process oil is a combination of paraffinic, naphthenic, and aromatic compounds with varying molecular weight. It is used as raw material component or as an aid in processing of materials in industries such as textile, rubber and polymer. Process oil is produced by refining processes such as catalytic dewaxing process and advanced hydrocracking. Process oil obtained after refining is colorless and exhibits high performance qualities such as high saturation, low volatility, and increase in purity and stability. It is nearly free of polar compounds, aromatics, and sulfur. Materials that can be used as process oil include chemical peptizers, petroleum oil, fatty acid soaps and esters, liquid polymers, partially vulcanized rubber, and waxes. Process oil is used in a wide range of applications in various industries such as plastics, polymer, rubber, tire, adhesives, personal care, defoamers, and textile.
