Lubrizol Unveils Zinc-Free Hydraulic Additive to Power Sustainable Performance
Lubrizol has taken a bold step forward in sustainable industrial chemistry with the launch of Lubrizol® AH933ZF, a zinc-free hydraulic additive engineered to deliver robust performance while protecting environmentally sensitive ecosystems. As the global demand for cleaner technologies intensifies, this new additive represents a major milestone for hydraulic systems used across construction, mining, forestry, and marine industries.
Zinc-free hydraulic fluids have surged in popularity as regulators, OEMs, and industries strive to reduce the environmental risks associated with traditional zinc-based additives. These concerns primarily stem from the potential contamination of soil and water sources when hydraulic fluids leak or are disposed of improperly. Lubrizol’s latest breakthrough demonstrates that sustainability and high performance can coexist seamlessly.
Meeting Critical OEM Standards with Sustainable Science
Lubrizol® AH933ZF is more than just an alternative, it’s a technological advancement. Backed by the company’s deep expertise in additive chemistry, the formulation meets stringent OEM specifications while maintaining the durability and reliability expected from Lubrizol’s industrial oil portfolio.
The additive was developed to serve demanding applications where environmental exposure is a concern, from heavy-duty mining machinery to marine hydraulic systems. Its zinc-free composition helps manufacturers meet tightening environmental regulations without compromising performance.
Jared Cornett, Product Manager for Industrial Oils at Lubrizol, commented: “In a world demanding cleaner solutions with enhanced performance, Lubrizol continues to lead the way. Lubrizol® AH933ZF is a demonstration that high-performance, zinc-free hydraulic fluids are not only possible, but that they can outperform conventional formulations with the right science.”
Key Benefits of Lubrizol® AH933ZF
This new additive package brings a suite of benefits that contribute to enhanced productivity, lower operational costs, and greater reliability in critical machinery:
- Reduced Downtime and Extended Equipment Life: The additive’s advanced anti-wear chemistry offers exceptional protection for components such as pumps and valves. By minimising metal-to-metal contact, it reduces wear and tear, ensuring longer equipment life and lower maintenance costs.
- Extended Drain Intervals: Thanks to its oxidation resistance and superior thermal stability, Lubrizol® AH933ZF extends service life, reducing the frequency of oil changes. This not only cuts costs but also minimises waste and environmental impact.
- Precise Operation and Enhanced Productivity: Air release and foam control properties improve hydraulic responsiveness, leading to smoother operation and improved precision, vital for machinery in construction and heavy-duty industries.
- Formulation Flexibility: With a broad base oil compatibility window, Lubrizol® AH933ZF allows formulators to create high-performance fluids using various Group II base oils. This enables faster development, reduced formulation costs, and shorter time to market.
Zinc-Free Fluids on the Rise
The move towards zinc-free formulations reflects a broader shift across industrial sectors. According to a study by Kline & Company, demand for zinc-free hydraulic fluids in North America and Europe is expected to grow at a compound annual growth rate (CAGR) of 4.25% between 2024 and 2029. Meanwhile, zinc-based formulations are projected to decline at -0.43% CAGR over the same period.
This growth is driven by several factors:
- Tighter environmental regulations in Europe and North America restricting zinc-based additives.
- OEM recommendations encouraging environmentally friendly alternatives.
- End-user demand for longer-lasting, sustainable hydraulic solutions.
In this evolving landscape, Lubrizol’s zinc-free innovation positions the company as a frontrunner in the race toward cleaner industrial chemistry.
Sustainability Meets Performance
Lubrizol’s science-led approach enables additive development that aligns with the sustainability goals of major equipment manufacturers. The company’s focus on balancing environmental protection with mechanical efficiency means its solutions support customers in meeting both regulatory and operational targets.
Zinc-based additives, while effective as anti-wear agents, can release toxic heavy metals into the environment when fluids leak or are disposed of. By eliminating zinc entirely, Lubrizol® AH933ZF reduces these risks without sacrificing performance or reliability.
Furthermore, extended oil drain intervals contribute to reduced waste generation, while improved thermal stability means less fluid degradation over time a win-win for both operators and the planet.
