Buy Base oil 4cst
Repairs and maintenance of industrial devices is one of the most important pillars of the economy of industry, which is given more attention. In the past, due to the small population, industrial machines were not used much, but due to the increase of Supply ,machines now work more and this causes the cost of their maintenance and repairs to rise. These costs are usually related to oil machines and machine lubricants and other things.
The continuous operation of the machines has made the experts think of a higher quality oil than the base oils of group one and two. The base oils were the base oil group 3 that were explained later. This type of oil (base oil group 3) is purer than others, more resistant to higher temperatures and more suitable for modern applications. In the following, base oil 4cst examined in more detail.
What is base oil 4cst?
This oil is obtained from refining crude oil. After refining, the extraction process is done with solvent. Next, in order to increase the purity of the oil, they use the dehydrogenation process. In this step, hydrogen and catalysts are used to separate nitrogen, oxygen and sulfur elements. The high precision in the purification process has resulted in an increase in the price of base oil 4cst.
This product has better specifications than others and can withstand more pressure and heat. This has made them use it as an additive to prepare secondary oils.
Specification of base oil 4cst
The characteristics of this base oil (base oil 4cst) are different from other groups. In the following, we will examine its most important characteristics quantitatively and qualitatively.

Applications of base oil 4cst
base oil 4cst is widely used due to its unique characteristics. Some of these applications are:
1- Car engine oil
High Quality engine oil is a combination of several oils with different chemical formulas. base oil 4cst is considered a suitable additive due to its high viscosity index and low amount of sulfur and aromatic compounds. Adding this oil to engine oil stabilizes the viscosity at different temperatures and reduces friction and oil deposits in the ducts.
2- Lubricant for turbines
Turbines need periodic service, and lubrication of different parts of the turbine is one of these services. Special lubricants are used to lubricate turbines. These lubricants are a combination of base oil, corrosion inhibitors, oxidation inhibitors, defoamants, and demulsifiers. More than 90% of this composition is base oil and the rest of the ingredients are considered additives.
3- Hydraulic oil
Hydraulic oil is used to lubricate gear components and sometimes to transfer power from one part to another part. Of course, hydraulic oil is a combination of several oils and base oil 4cst is also one of the components of hydraulic oils.
4- Viscosity index regulator
Viscosity index shows the amount of changes in oil viscosity with temperature changes. High viscosity index means oil viscosity changes less against temperature changes. For some special machines which industrial oil is not produced, technicians combine several oils. base oil 4cst is used when they want to improve the viscosity index of the final solution.

Benefits of base oil 4cst
1- The compatibility of this oil with other mineral oils and ether compounds.
This oil is considered a good supplement for this reason because it has the ability to dissolve and is compatible with other oils and compounds.
2- Longer lifetime
Due to its good viscosity index, flash point and pour point, this oil is resistant to heat and pressure and does not lose its lubrication and fluidity.
3- Because this oil (Base oil 4cst) is saturated, it has few free molecules to react with oxygen. The reaction of oxygen with free molecules increases the internal friction of the oil. The internal friction of the oil causes the oil to lose its fluidity over time. Also, the internal friction of the oil causes the friction of the oil with the metal surface.
4- The low pour point of this oil makes it easier to pump. Industrial machines, especially machines that move and do not have a fixed base, work at different temperatures. One day they may be in cold weather and the next day in very hot temperature. This makes it necessary to choose a suitable base oil.
5- Because this oil has a bright color and transparent appearance, it can be used as a test oil. In fact, by passing this oil through the ducts, the color of the oil changes, and from this change in color, you can see how closed these ducts are or how much deposits remain in them.
price of Base oil 4cst
Because petrochemical products are extracted from crude oil, they are dependent on the global price of crude oil. Of course, it should be noted that the quality of each company’s product is different from the other and, accordingly, its price is also different. The price of crude oil has never been stable, and this has caused the price of products such as base oils to always fluctuate. Dear customers, you can contact us to know the current price of Blackwater products.
