Pour point depressants are substances that lower the pour point of petroleum and its products. Pour point depressants lower the pour point of petroleum or petroleum products by inhibiting the aggregation of wax crystals. Wax crystals are a type of crystal in petroleum or petroleum products that aggregate to make them less fluid or even… Read more

Motor oil is a vital component in maintaining and servicing your car. It not only has the function of lubrication and cleaning, but also effectively protects the engine and extends the service life of the car. To meet these requirements, various additives are often added to engine oil. This article will explore 6 additives commonly… Read more

Paraffinic base oil pour point depressants are additives that help reduce the pour point of paraffinic base oils. Pour point is the lowest temperature at which oil can flow or pour. Paraffin base oils tend to solidify at lower temperatures due to the presence of waxy paraffin molecules. Pour point depressant additives change the crystal… Read more

TBN 400 (total base number) and calcium sulfonate grease is a grease… Read more

ISO (International Organization for Standardization) is the standard that defines oil viscosity classifications. It provides a standardized grading system of lubricant viscosity called ISO VG (viscosity grade). Viscosity index (VI), on the other hand, is a measure of the change in oil viscosity with temperature. It quantifies the change in oil viscosity at different operating… Read more

Demulsifiers and emulsifiers are two common chemical agents that are widely used in many industries and daily life. While they can both be used to handle liquids, there are distinct differences between them. First of all, demulsifiers are mainly used to destroy the stability of emulsions and separate the liquid components in the emulsions. This… Read more
