HybriCal™ is a lithium-free grease thickener system designed to help manufacturers manage supply risk and cost volatility.
Internal testing indicates up to 30% lower production global warming potential, up to 5% cost advantage, and 36% faster production times.
The system delivers comparable or improved grease performance while supporting a more resilient and sustainable supply strategy.

As lithium supply and pricing become increasingly unpredictable—driven by EV battery demand and global trade pressures—grease manufacturers are seeking reliable, lower-risk alternatives. Lubrizol’s HybriCal™ grease thickener system offers a lithium‑free solution that delivers comparable performance with meaningful sustainability and cost advantages.

HybriCal™ combines calcium sulfonate and anhydrous calcium to provide broad thermal stability, excellent cold-temperature pumpability, and an improved health and safety profile. The system meets NLGI HPM core specifications and can achieve HL performance when paired with Lubrizol® 5288B HL package.

Key benefits include:

Up to 30% reduction in production global warming potential (GWP)*
Up to 5% cost advantage*
36% faster production times*
Comparable or improved performance vs. lithium greases across wear, oxidation, water resistance, and thermal stability tests*

*Based on internal testing

HybriCal™ Grease Thickener Offers a Lithium-Free Alternative with Lower GWP
