## Description

Halocarbon 25-20M Grease is a high-viscosity, relatively firm fluorinated grease thickened with high-molecular-weight PCTFE powder, with an NLGI grade of approximately 3. Engineered with safety priority, it features strong chemical inertness and is nonflammable. Compatible with oxygen and chlorine, it meets lubrication requirements in extreme environments. Its unique fluorinated formulation delivers stable and reliable lubrication protection under severe operating conditions.

## Features

Halocarbon 25-20M Grease features excellent chemical resistance and thermal stability, with an operating temperature range of -20°C to 120°C. It has low compressibility and favorable lubricity, suitable for high-temperature, high-pressure and strongly corrosive environments. This grease is non-toxic, odor-free and free of flammable components, guaranteeing operational safety and environmental friendliness.

Halocarbon 25-20M Grease is widely used in industrial applications requiring chemical corrosion resistance and high-temperature tolerance, including chemical equipment, valve sealing, aerospace and electronic devices. It is compatible with strong oxidizing media such as oxygen and chlorine, meeting the requirements of high safety and high-performance lubrication. It is especially ideal for mechanical lubrication and sealing protection under extreme working conditions.
