P-FPG 182 is a smooth, buttery, white grease. It has been developed to operate over a broad temperature range and under demanding chemical and vacuum conditions. It exhibits favorable performance, as demonstrated in bearing life tests, showing a lifespan significantly exceeding that of comparable products.

It is designed for use in challenging operating environments and can be applied to bearings, gears, and as a lubricant for O-rings and elastomers.

- Composition and Appearance: Formulated with perfluoropolyether (PFPE) base oil and a specialized high-performance polytetrafluoroethylene (PTFE) thickener, this lubricant presents as a smooth, creamy white grease.
- Temperature Performance: Demonstrates a wide operational temperature range from -73°C to 204°C (-99°F to 399°F), maintaining stable lubricating properties under extreme temperature conditions.
- Chemical Resistance: Exhibits exceptional chemical inertness, providing robust resistance to hydrocarbon fuels, liquid oxygen, and various other chemical agents, ensuring safe utilization in environments exposed to these substances.
- Viscosity Profile: The base oil exhibits a viscosity of 50.45 cSt at 40°C. This viscosity characteristic enables the lubricant to deliver appropriate film thickness for components under varying operational demands, minimizing friction and wear.
- Application Scope: Primarily intended for aerospace implementations, specifically for lubricating bearings, gears, O-rings, and elastomers in aircraft and spacecraft. Furthermore, it finds utility in select high-end industrial sectors with stringent lubrication demands and challenging operational settings, such as semiconductor fabrication and advanced electronics manufacturing.
