Tetramer castor oil ester is a castor oil acid polyester compound, which can be used as the lubricating additive of water-based Metal Working Fluid. The strong polarity of its structure makes it have good lubricating performance, and it is recommended for aluminum cutting and rolling. The tetramer has a certain degree of self emulsifying property. It is very easy to emulsify in the presence of a small amount of alkali. It is easy to add into the aqueous formula system, and has good hydrolysis stability. Tetramer can be widely used in metal working fluids such as emulsions and microemulsions to provide good lubrication performance, especially for rolling oils, emulsions and semi synthetic cutting fluids for aluminum processing.
The product of tetramer castor oil ester is light and transparent, which can make the cutting fluid low foam, has good compatibility with the formula, and has no adverse effect on the stability of the system. It has good solubility in paraffin based and naphthenic base oils, and is a good choice for cutting fluid, especially for aluminum alloy processing. Market of tetramer castor oil ester As far as tetramer castor oil ester is concerned, the main raw material of tetramer is ricinolic acid, which is processed by saponification of castor oil. Recently, the price of castor oil is weak. The price of castor oil fell this week, but the external market did not change much, while the domestic price began to descend to a higher level. Many castor oil manufacturers were more active in shipping, which shows that the domestic downstream demand for castor oil is really poor. It seems that there is still a possibility of decline in the later period. It is suggested to wait and see in the short term. It is also recommended to carefully stock up on demand if there is a strong demand for tetramer castor oil ester, which does not rule out the possibility of further price decline in the future.
