Product Description
MOLYKOTE® Z Powder is a charcoal-gray to black, free-flowing molybdenum disulfide solid lubricant for metallic contacts and lubricant-modified materials. It can be dry-burnished onto clean metal surfaces or incorporated into self-lubricating plastics, elastomers, sintered-metal parts, metalworking compounds, and brake-lining formulations. The powder is suited to heavy-load, slow-speed, press-fit, run-in, dusty, and temperature-extreme applications. With 98% typical MoS2 purity, a service-temperature range of −185°C to 400°C in atmosphere, and capability up to 1,100°C in vacuum, it supports lubrication where conventional liquid or grease films may be unsuitable.
Key features
- High-purity solid lubricant: Contains a typical 98% molybdenum disulfide content.
- Broad temperature capability: Supports service from −185°C to 400°C in atmosphere and up to 1,100°C in vacuum.
- High load-carrying performance: Provides a typical Almen-Wieland OK load greater than 20,000 N.
- Low-friction behavior: Provides a typical press-fit coefficient of friction of 0.048 under the stated test method.
- Flexible use: Can be dry-burnished onto metal or added to plastics, elastomers, sintered metals, and lubricant formulations.
- Extreme-environment suitability: Supports heavy-load, slow-speed, dusty, run-in, and press-fit applications.
