Antiwear Zinc Free Hydraulic Oil Additives Pacakge
Advanced Protection for Eco-Sensitive Hydraulic Systems
This premium zinc free hydraulic oil additive has excellent high-pressure extreme pressure anti-wear, anti-oxidation, anti-emulsification and thermal oxidation stability, excellent hydrolysis stability, good filterability, and effectively prevents corrosion of silver and copper hydraulic parts.
It is used to prepare various types of anti-wear hydraulic oils of various viscosity grades (15, 22, 32, 46, 68, 100, 150) in the national standard GB11118.1-2011.
This zinc free hydraulic oil is widely used in various types of large-scale engineering machinery, ships, vehicles such as cranes, excavators, dump trucks and other high-pressure hydraulic systems, as well as hydraulic systems with plunger pump pressures up to 34.5Mpa and vane pump pressures up to 17.5Mpa. It can also be used for other mechanical lubrication parts that require high loads.
Product Introduction
Our zinc free hydraulic oil additive is a synergistic zinc-free anti-wear package utilizing advanced boron-sulfur chemistry, engineered to replace ZDDP in environmentally sensitive hydraulic systems. Its metal-free formulation delivers superior wear protection while meeting stringent ecological and food safety requirements where conventional additives fail.
Performance Advantages
- Zinc-Free Wear Protection
Achieves <0.35 mm scar diameter in ASTM D4172 Four-Ball Test (40% better than conventional AW oils).
- Water Tolerance Excellence
Maintains film strength with 1% water contamination (DIN 51399 pass).
- Seal Compatibility
90% less NBR seal shrinkage vs. ZDDP fluids (ASTM D471 @ 1,000h).
- Oxidation Stability
5x extended RPVOT life (>2,500 min per ASTM D2272).
- Filterability
ISO 13357-1 filterability >95% at 3μm.
