Products Description of GALDEN (TM) HT70 CAS#69991-67-9

1. Compared with hydrocarbon lubricants, perfluoropolyether lubricants have basically similar molecular structures. However, due to the stronger C-F bond replacing the C-H bond in hydrocarbons, the presence of strong covalent bonds of C-O and C-C (see Table 1), and the neutral characteristics of PFPE molecules, PFPE has high chemical inertness, extremely high oxidation resistance, strong corrosion resistance, good lubrication performance, high decomposition temperature, thermal stability and oxidation stability, as well as good chemical inertness and insulation properties, which are unmatched by other lubricants. PFPE with a larger molecular weight also has low volatility, a wider liquid temperature range and excellent viscosity-temperature characteristics.

2. Compared with chlorofluorocarbon lubricants, perfluoropolyether lubricants have a wider operating temperature range. At the same time, they do not have the disadvantages of chlorofluorocarbons that are easy to evaporate at high temperatures and become viscous and thick at low temperatures. Since there is no chlorine in its molecules, it will not corrode the bearings due to the pressure of the lubricant when used in high-load bearings.

3. Compared with fluorosilicone lubricants, although the viscosity and evaporation rate of perfluoropolyether lubricants are comparable to those of fluorosilicone lubricants, their lubrication effect and chemical stability are much better than those of fluorosilicone lubricants. In addition, the main physical and chemical properties of PFPE include: shear stability, biological inertness, low surface energy, good lubricity and compatibility with plastics, metals and artificial rubber, etc.
