Treated Distillate Aromatic Extracts (TDAE)

Treated Distillate Aromatic Extracts (TDAE) is mineral oils, not classified as

carcinogenic, as they contain a DMSO extract IP346 inferior to 3% and consequently a reduced PAH content, Typically by factor 20-50 lower than HA oils.

Types of RPO by different Viscosities
Rubber Process oil is produced by Lub Cut.Crude oil distillation process is obtained material to lube cut.The companies named RPO lube cut with a solvent composition and the chemical interactions and isolation RPO extract (product of solvent extraction RPO) material extracted is called Raffinate.
Structural mechanism of action of some additives to lubricant
Antiwear mechanism of action of some chemical elements added to lubricant is studied. These elements are transferred from the lubricant into the surface layers of the sliding pair during friction. The mechanism is based on the influence of these elements on the stacking fault energy (SFE) of the materials in the friction pair and leads to changes in the fragmented structure formed in the metals under plastic deformation. Work hardening of the metal surface layers and their predisposition to wear are changed accordingly. Copper and Armco iron, as typical FCC and BCC metals, were chosen for the friction pair materials. Si, Ni, Zn, Co and Ti were used as the additive components to the lubricant. It was found that the addition of different elements to the lubricant leads to alloying by these elements of the surface layers of the metal during the process of friction. It was found that alloying by elements which decreases the SFE of the metal, the average size of surface layer fragments formed during friction increases and the wear rate decreases. The possibility of controlling the wear resistance of metals during friction through the use of appropriate additives is discussed.
Group II and III base oils are high quality oils containing less than 10% aromatics and less than 300 ppm sulfur as defined by API publication 1509. Group II and III base oils made using a hydrocracking/ ISODEWAXINGâ /hydrofinishing catalyst combination typically have about 1% aromatics or less and almost undetectable amounts of sulfur and nitrogen. The virtual absence of heteroatom containing compounds coupled with an inherently low aromatic content gives them superior oxidation stability relative to Group I base oils. The primary factor that influences the oxidation stability of Group II and III oils is the aromatic concentration. But as the aromatic content approaches zero, oxidation stability is influenced more by the saturates composition, particularly the paraffin and polycyclic naphthenes content and distribution. This paper discusses the types and distribution of naphthene and aromatic compounds in highly hydroprocessed Group II/III base oils, and their relative influence on oxidation stability.
rubber processing oil is used as a lubricant in tyre(tire) industry and as a raw material for plastic, chemical and rubber industry.
