Damping grease is a functional grease made from specially selected polymers, specialty additives, and thickeners through a unique manufacturing process. It features excellent adhesion, high viscosity, superior lubrication performance, chemical stability, and mechanical stability. It is particularly suitable for positions between plastics and metals that require long-term damping (buffering, resistance) and lubrication.
Typical application areas of damping grease include:
Sealing and leak-prevention parts: Such as sealing valves in water or fuel gates, used for lubrication and leak-proof filling.
Precision instruments: Parts that require damping and buffering.
Household products: Items that need cushioning or a naturally comfortable tactile feel.
Hardware and power tools: High-end door hinges, faucets, power tools, and movable joints in plastic toys.
Office equipment and mechanical structures: Internal plastic or metal moving parts in office equipment, toys, gearboxes, etc., requiring lubrication, noise reduction, shock absorption, or resistance functions.

PUR Hot Melt Adhesive (Moisture-Curing Polyurethane Hot Melt Adhesive) has become the preferred solution for bonding, protection, and assembly in the electronics industry due to its excellent performance. It is a 100% solid, solvent-free, and non-toxic adhesive, notable for its rapid curing: solid at room temperature, it melts upon heating for application, achieves quick initial tack upon cooling under pressure, and then completes final curing through reaction with ambient moisture.
Unique Curing Mechanism:
Applied in a molten state, it achieves initial adhesion upon cooling and forms high-strength polymers through moisture curing, significantly enhancing final bonding strength, heat resistance, and low-temperature performance.
Irreversibility:
Unlike most reversible conventional hot melts, PUR adhesive becomes irreversible after moisture curing (does not remelt upon reheating), providing superior high- and low-temperature durability.
Outstanding Electronic Applications:
High Bonding Strength: Achieves strong adhesion after curing, meeting the requirements of most electronic products.
Precision Application: Excellent control over bead size, ideal for narrow frames and fine-feature designs.
Reworkability: As a thermoplastic polyurethane, bonded components are relatively easier to disassemble for repair.
Environmentally Friendly and Safe:
Solvent-free and compliant with environmental standards.
Thanks to the above advantages, PUR hot melt adhesive is widely used in various stages of electronic product manufacturing, including:
Screen assembly and component bonding for smartphones, tablets, learning devices, GPS navigators, and wearable devices.
Window bonding and housing structure adhesion.
Battery fixation.
Flat surface sealing.
PCB assembly and protection.
After production, it is essential to thoroughly clean the adhesive rollers to prevent residual glue from curing and affecting subsequent production or product quality.
EUBO PUR Hot Melt Adhesive:
EUBO’s PUR hot melt adhesive is a general-purpose, single-component, moisture-curing hot melt with good initial tack at room temperature. From a performance perspective, we focus on enhancing PUR hot melt properties—such as viscosity, melting temperature, melt viscosity, and initial tack. Choosing the right adhesive is therefore a solid first step toward optimal results.
Low-Temperature Damping Grease is specially designed for precision mechanisms operating under high and low temperature conditions (-20℃ to 80℃). Its core advantage lies in maintaining stable torque across a wide temperature range, ensuring effective damping and shock absorption for precision positioning mechanisms, fine-tuning devices, and stiction/ buffering components. This allows moving parts to operate smoothly, gently, and accurately.
Typical Applications Include:
Damping and anti-slip mechanisms for lens focusing in cameras, microscopes, telescopes, and rangefinders
Turntable damping gears and switch devices in disc players
Other precision mechanical components requiring stable damping performance at low temperatures
To ensure optimal performance and safe use, please strictly follow these precautions:
Clean and Dry: Before application, ensure that the area to be greased is completely dry, clean, and free of contamination.
Prevent Contamination: During use and storage, strictly prevent dust and foreign particles from mixing in. Always tightly seal the container after use.
No Mixing: Do not mix with other types of greases, as this may cause adverse reactions, reduce performance, or damage components.
Plastic Compatibility: For special plastic parts, conduct a compatibility test or obtain explicit approval from the plastic manufacturer before use to avoid swelling, embrittlement, or other adverse effects.
Proper Storage: Store the product in a clean, dry, cool, and dark place.

1. Anti-Wear Performance Test (SH/T 0204)
Using a specialized anti-wear testing device, under a specified load, the upper steel ball rotates relative to three stationary steel balls on the lower surface, which are coated with the grease sample. After the test, the wear scar diameters on the three lower steel balls are measured. The size of the wear scars is used to evaluate the anti-wear performance of the grease.
2. Four-Ball Test Method (GB/T 3142)
In the four-ball test, grease is applied to a ball cup, and under a specified load, the upper bearing steel ball rotates at a set speed against three stationary steel balls below. After a period of operation, the wear scar diameters are measured to evaluate the extreme pressure (EP) performance of the grease.
There are three common expressions for this method: PB value, PD value, and ZMZ value:
PB value: The maximum load under which no seizure occurs during the test, expressed in Newtons (N).
PD value: The minimum load at which the rotating ball and the three fixed balls weld under the test conditions, expressed in N.
ZMZ value: An indicator of the grease’s resistance to extreme pressure under applied loads. During the test, the load is incrementally applied to the three stationary balls in 0.1 logarithmic units, and the first ten seizure load results are used to calculate the ZMZ value, expressed in N.
3. Timken Test
This test is performed using a Timken test machine. Grease is applied between the friction surfaces of a metal ring and steel block under a specified load and speed. After a period of operation, the wear marks on the metal balls are examined to determine the EP performance of the grease, represented by the OK value.
Purpose: To analyze the grease’s ability to resist loads under line contact.
Test Method: SH/T 0203
4. Four-Ball Extreme Pressure Test (GB/T 12583)
This method is also expressed using three indicators: PB value, PD value, and LWI value.
LWI value: Indicates the extreme pressure capacity of a sealed grease under a limiting load. It is determined by applying incremental loads in 0.1 logarithmic units on the three stationary balls and performing ten tests before the seizure point. The average corrected load represents the LWI value.
