Why Choose MOLYKOTE® EM-30L Grease for Plastic and Precision Components?

Why MOLYKOTE® EM-30L Grease Is Trusted for Plastic Lubrication

Selecting the correct lubricant is essential when working with plastic gears, sliding mechanisms, actuators, and precision assemblies. MOLYKOTE® EM-30L Grease is specifically developed to provide reliable lubrication for plastic-to-plastic, plastic-to-metal, and metal-to-metal contact surfaces while maintaining long service life and excellent material compatibility. It is formulated with a PAO synthetic base oil, lithium soap thickener, and PTFE solid lubricants, offering stable lubrication across a wide operating temperature range.

Key Features of MOLYKOTE® EM-30L Grease

Unlike conventional greases that may attack plastics or migrate from lubricated surfaces, MOLYKOTE® EM-30L Grease provides several performance advantages:

• Excellent compatibility with most engineering plastics and elastomers
• Suitable for plastic/plastic, plastic/metal, and metal/metal interfaces
• Long-lasting lubrication that reduces maintenance frequency
• Low oil separation and low evaporation for cleaner operation
• Silicone-free formulation to help avoid electrical contact contamination
• Outstanding low-temperature performance from -45°C to 150°C
• White grease with NLGI Grade 1 consistency for smooth movement and easy application
