Graphite Lubricants for Extreme Pressures
High-purity crystalline graphite remains the gold standard for high-temperature boundary lubrication. Our synthetic dispersions ensure uniform coverage and shear-resistant boundary films up to 1200°C.
Tribological Dynamics of Crystalline Graphite
Crystalline natural graphite achieves its outstanding lubrication properties through its layered hexagonal lattice structure. Under high shear forces, these layers slide past one another easily, resulting in an exceptionally low coefficient of sliding friction.
The synthetic carrier fluid of our PROMET Graph-Lube series is designed to distribute the graphite solids uniformly across the die surface before clean volatilization, leaving a highly resilient dry protective film that prevents direct metal contact and die scoring.
