Damping grease is also called high-viscosity grease, shock-absorbing grease, resistance oil, etc. It is a grease refined from high-purity inorganic thickener, synthetic oil, and various additives.Damping grease is a type of grease that plays a dual role of damping and lubrication between two friction surfaces.
Because the damping grease has a high viscosity, it is used to join parts, allowing large gaps and tolerances, and has a buffering effect, making the parts smooth and precise, and can improve the feel and reduce noise.It can help the instrument prevent the intrusion of moisture, dust and other contaminants, and also reduce wear and prolong product life.
The basic requirements for damping grease：
1. The higher viscosity can meet requirements of the specified rotational and sliding torque.
2. Good viscosity-temperature can be used in a wide temperature range, can adapt to hot and cold weather, and it will not cause too little damping in summer or in tropical regions, and will not cause too much damping in winter or in cold regions, or even solidified and unable to turn.
3. Excellent colloidal stability, no oil separation during using to cause pollution of related parts.
4. Low evaporation and long service life.
5. Good corrosion resistance, does not corrode the metal in the use part, and has good compatibility with related plastic parts.
6. Good adhesion and easy application.
7. Good lubricity and meets environmental protection requirements.
Application Range:
Used for lubrication of any free motion area that needs to be controlled of optical instruments, electronic instruments, measuring instruments, sanitary ware, gear systems, home appliance controls, switch knobs, entertainment equipment, laser controls, potentiometers, TV/radio tuning, and stepper motors.
