XYC JM 44-702 KR 1KG Synthetic Damping Grease for Noise Reduction and Plastic Components
XYC JM 44-702 KR Synthetic Damping Grease
XYC JM 44-702 KR is a high-viscosity synthetic specialty grease developed for applications requiring mechanical damping and noise reduction. This noise damping grease is designed to provide controlled resistance in slow-moving components and help create a softer tactile feel.
The formulation is based on synthetic hydrocarbon oil and lithium soap thickener. As a synthetic damping grease, it is suitable for selected sliding contacts and mechanisms where movement feel, acoustic performance and lubrication are important.
This plastic component grease can be considered for compatible plastic-to-plastic and plastic-to-metal material pairings. Before use in production, verify compatibility with the actual component materials and operating conditions.
Mechanical Damping and Noise Reduction
XYC JM 44-702 KR is designed to provide mechanical damping in suitable moving components. Its high-viscosity formulation can help control movement and reduce operating noise in mechanisms that require a consistent tactile response.
This noise damping grease is particularly relevant to selected automotive interior components, including switches, rotary controls, ventilation flaps and adjustment mechanisms. The achieved damping effect depends on the component geometry, contact pressure, material combination and quantity of grease applied.
For applications requiring controlled movement rather than free-running lubrication alone, this synthetic damping grease offers a specialized solution. Its use as plastic component grease should be validated through testing on the finished assembly.
High Viscosity Synthetic Formulation
The product uses synthetic hydrocarbon base oil with an approximate kinematic viscosity of 720 mm²/s at 40°C and lithium soap as the thickener. This high-viscosity formulation is intended for lubrication points where mechanical resistance and damping are important.
As a synthetic damping grease, XYC JM 44-702 KR can help provide the desired movement characteristics in selected slow-moving mechanisms. Its performance should be assessed according to operating force, movement speed, temperature and service requirements.
The product also serves as noise damping grease in suitable mechanisms where reducing unwanted sound is an objective. When selecting plastic component grease, users should confirm that the lubricant meets the material compatibility and movement requirements of the application.
Plastic Compatibility and Material Pairings
XYC JM 44-702 KR is designed for plastic-to-plastic and plastic-to-metal contacts. The original product documentation reports compatibility testing and indicates neutrality toward most plastic materials, while recommending that users check compatibility before series application because plastic compositions vary.
This plastic component grease may be considered for guide rails, rotary controls, switches and other mechanisms containing compatible plastic parts. Actual compatibility should be confirmed using the specific polymer, additives, component stress and environmental conditions.
For applications where movement feel and acoustic performance are important, this noise damping grease can be evaluated as part of the complete component design. The selected synthetic damping grease should be tested to confirm material compatibility and the required damping effect.
Wide Temperature Operating Range
The documented service temperature range for XYC JM 44-702 KR is -50°C to +130°C. This range makes the product suitable for evaluating in applications that require lubrication and damping under both low-temperature and elevated-temperature conditions.
The source documentation also describes tolerance of short-term temperature peaks up to +180°C in enclosed systems. This should not be treated as a continuous service rating. Actual operating conditions and exposure duration must be considered when selecting the product.
For suitable plastic component grease applications, temperature testing should be performed on the assembled mechanism. The required movement feel, noise damping grease performance and long-term behaviour should all be verified under actual service conditions.
Low Oil Separation and Application Inspection
The product has a documented oil separation value of no more than 3% by weight after seven days at 40°C. This property helps characterize the grease's oil retention under the specified test conditions.
The original RA 44-702 product also includes a UV indicator for inspecting minimum-quantity lubricant application. The documentation specifies a UV check wavelength of 366 nm. This can support production quality checks where confirming lubricant application is important.
When applying this synthetic damping grease, use an appropriate quantity and method for the component design. Consistent application helps support the intended movement and noise-control characteristics of the noise damping grease.
Automotive and Precision Engineering Applications
XYC JM 44-702 KR can be considered for selected automotive interior and precision mechanism applications. Examples in the source documentation include mechanical switches, rotary controls, ventilation flaps, sun visors, cup holders, storage boxes, window-lifter guide rails, armrest mechanisms and seat-adjustment systems.
These components may require a balance of lubrication, controlled movement and noise reduction. This plastic component grease is designed for suitable material pairings where tactile feel and acoustic damping are important.
Before adopting the product, confirm the required operating force, temperature range, material compatibility and application quantity. Testing the complete assembly helps determine whether XYC JM 44-702 KR provides the required synthetic damping grease and noise damping grease performance.
Product Specifications and Storage
XYC JM 44-702 KR is offered in a 1KG package. The documented colour is beige, the density is approximately 0.87 g/cm³ at 20°C, and the worked penetration is 265–295 × 0.1 mm at 25°C. The drop point is at least 180°C.
The stated minimum shelf life is approximately 36 months from the date of manufacture when stored in an unopened original container in a dry, frost-free place.
Store and apply the product according to the applicable handling instructions. Before series production, conduct compatibility and performance testing to confirm that the noise damping grease, synthetic damping grease and plastic component grease requirements of the application are met.
