XYC RA 44-702 Synthetic Specialty Grease

XYC RA 44-702 is a high-viscosity synthetic specialty grease designed for mechanical damping, noise reduction and controlled movement in precision components. This automotive damping grease is intended for mechanisms where consistent shifting force, smooth operation and a soft tactile feel are required.

With synthetic hydrocarbon base oil and a lithium soap thickener, XYC RA 44-702 is designed for plastic-to-plastic and plastic-to-metal friction pairs. As a plastic compatible grease, it is suitable for evaluating in automotive interior assemblies and other mechanisms requiring controlled movement.

The grease also serves as a noise reduction grease for selected slow-moving components in which friction behaviour and mechanical damping influence operating sound.

Mechanical Damping and Noise Reduction

Mechanical noise can occur when sliding components move unevenly or when friction changes during operation. XYC RA 44-702 provides high-viscosity lubrication designed to damp mechanical movement and help reduce unwanted noise.

Thisautomotive damping grease is suitable for selected switches, rotary controls, sliding rails and adjustment mechanisms. It helps establish defined shifting forces and compensate for component tolerances.

For assemblies where tactile quality is important, this noise reduction grease can support a smoother, more controlled operating feel.

Plastic Compatibility and Friction Pair Applications

Many automotive interior components use engineering plastics in combination with other plastics or metal parts. Lubricants used in these assemblies need to provide suitable friction characteristics without causing unacceptable material damage.

XYC RA 44-702 is designed for plastic-to-plastic and plastic-to-metal contacts. The original product information reports testing according to DIN EN ISO 22088 for stress cracking, with results indicating neutrality to most plastic materials.

As a plastic compatible grease, it can be considered for selected interior mechanisms. However, actual compatibility depends on the specific polymer formulation and component design, so testing with the intended materials is recommended before mass production.

Temperature Performance and Lubricant Stability

XYC RA 44-702 has a specified service temperature range of -50°C to +130°C. For enclosed systems, short-term temperature peaks of up to +180°C may be tolerated under the conditions stated in the product information.

Its reported base oil viscosity is approximately 720 mm²/s at 40°C, and its worked penetration is 265–295 × 0.1 mm. These properties help characterize the grease for applications requiring relatively high viscosity and controlled mechanical damping.

Thisautomotive damping grease should be selected according to actual operating temperature, movement speed, component loading and lubrication requirements.

Low Oil Separation and UV Inspection

XYC RA 44-702 has a reported oil separation value of no more than 3% by weight after seven days at 40°C. Low oil separation helps maintain the grease's consistency during the specified test conditions.

The formulation also contains a UV indicator that can be checked at a wavelength of 366 nm. This feature supports lubrication presence checks and quality inspection during minimum-quantity application.

For production processes requiring visual verification, this noise reduction grease provides an additional inspection feature alongside its mechanical damping function.
