MOLYKOTE® EM-D110 Grease: A High-Performance Solution Designed for Noise Reduction and Damping in Plastic Components

DuPont’s MOLYKOTE® brand announces the availability of EM-D110 Grease, a high-performance lubricant specifically engineered to address the challenges of noise, vibration, and material compatibility in plastic components and plastic-metal interfaces. Formulated with a high-viscosity polyalphaolefin (PAO) base oil and PTFE solid lubricants, this product delivers not only superior lubrication but also exceptional noise damping​ and material safety.

In automotive and precision electronics, noise and harsh engagement feedback from plastic gears and shafts are critical concerns affecting user experience. Conventional greases may cause stress cracking in plastics or contaminate electrical contacts with silicone. MOLYKOTE® EM-D110 addresses these pain points with precision:

• Material Compatibility: Formulated specifically for plastics, it is safe for use with common engineering thermoplastics like ABS, nylon, and POM, significantly reducing the risk of environmental stress cracking.
• Silicone-Free: Contains no silicone oils, eliminating the risk of contact failure in nearby electrical switches and connectors, making it ideal for automotive electronics and appliance control boards.
• High-Viscosity Damping: With a base oil viscosity of approximately 9,850 mm²/s at 40°C, it builds a resilient, thick film that absorbs vibration energy, transforming gear whine into smooth, quiet operation.

EM-D110 serves as an "acoustic improver" in addition to a lubricant, widely used in:

• Automotive Components: Driveshaft spline connections (reducing "clunk" during torque reversal), power seat adjusters, window regulator gears, and HVAC actuator gears.
• Precision Electronics & Appliances: Plastic gearboxes in printers, servo motor reduction mechanisms, and drive trains in household appliances (e.g., blenders, coffee makers).
• Industrial Equipment: Plastic slides, racks, and low-speed gearboxes in light industrial automation.

• Application: Clean surfaces before application. Apply using a brush, spatula, or automatic lubrication equipment. Its soft consistency (NLGI 0-1) allows it to flow into gear teeth and spline connections effectively.
• Safety: May cause skin or eye irritation. Wear appropriate protective equipment during handling. In case of contact, rinse immediately with plenty of water. Decomposition at temperatures exceeding 250°C may release hazardous fumes; ensure adequate ventilation.
• Storage: Store unopened containers in a cool, dry place (recommended below 20°C). Shelf life is 36 months from date of manufacture. Available in 1 kg cans (10 per case) and 16 kg pails to suit R&D and production needs.
