Isooctyl stearate

Short Description:

Monoester — Isooctyl stearate
Type: RJ-1651
Appearance: Colorless to light yellow transparent oily liquid
Chemical Properties: RJ-1651 has the characteristics of good wettability of isooctyl ester, which can provide very good lubricity in pure oil processing, and also provide permeability of processing fluid, such as high-speed cutting, drilling, punching, etc. In addition, it is a clean-burning, biodegradable synthetic ester, widely used as base oil and additive in pure oil, especially suitable for metal cutting fluids, and has good annealing cleanliness in rolling fluids. What is different from isooctyl oleate is that this material itself has no iodine value. It has very strong anti-oxidation ability in high temperature and harsh processing. In addition, the viscosity is close to No. 10 white mineral oil, so the base oil for semi-synthetic processing fluid is very emulsified. It also provides good lubricity and does not generate coke-like substances.
