The Key to Enhancing Lubrication Performance: Lubricant Additives
What is Lubricant Oil Additive?
Lubricant oil additives are chemical compounds added to base oils to improve the performance and longevity of lubricants. They enhance properties like viscosity, corrosion resistance, and wear prevention, making them essential for engines, machinery, and other industrial applications. The right additive package ensures efficient operation, reduces maintenance costs, and prolongs equipment life.
What is a hydraulic oil additive package?
Hydraulic oil additive packages are not single additives, but rather a combination of functional additives composed of various single-function agents such as anti-wear agents, antioxidants, rust inhibitors, anti-foaming agents, metal deactivators, and anti-emulsifiers, formulated through scientific proportioning and synergistic compounding. Their core mission is to endow base oils (such as mineral oils, synthetic oils, or CTL base oils) with "full operating condition adaptability" - for example, protecting hydraulic pumps from wear through anti-wear components, delaying oil aging through antioxidant components, inhibiting corrosion of metal components through rust inhibitor components, and ultimately ensuring the stable operation of hydraulic systems under complex environments such as high and low temperatures, high loads, and humidity.
As a globally leading professional hydraulic oil additive supplier , UNPChemicals has been deeply involved in this field for over a decade, always adhering to the philosophy of "making addition simple", and has built a product matrix covering different environmental protection standards and different load requirements. Its star products include:
High-Zinc Anti-Wear Hydraulic Oil Compound UNP AH502A: With a zinc content of 7.2% (wt), it is renowned for its excellent anti-wear performance and high load-carrying capacity. It can be formulated into high-performance anti-wear hydraulic oils that meet international standards such as GB11118.1-2011 and DIN51524, and is suitable for industrial hydraulic systems with stringent requirements for wear protection;
Low-Zinc Hydraulic Oil Compound UNP AH502B: While maintaining the basic anti-wear performance, it controls the zinc content at a lower level, taking into account both environmental compliance and equipment compatibility, and is suitable for scenarios with certain restrictions on heavy metal content;
Zinc-Free Hydraulic Oil Compound UNP AH502C: Completely free of zinc components, compliant with strict environmental regulations such as the European Union's RoHS, and specifically designed for hydraulic systems with extremely high environmental requirements, such as those in electronics and food machinery.
It is worth emphasizing that formulation design is the "decisive factor" for the performance of hydraulic oil additives. For the same combination of single additives, improper proportioning not only fails to exert synergistic effects but may also lead to performance conflicts - for example, excessive anti-foaming agent may cause a decline in air release performance, and a single high-dose anti-wear agent may sacrifice anti-rust effectiveness. Taking UNP AH502A as an example, its formulation precisely regulates the proportions of sulfur (13.5%), phosphorus (6.5%), and zinc (7.2%) to construct a "zinc-sulfur-phosphorus" synergistic anti-wear system. After adding 0.6% to 46# Group I base oil, the PB value (maximum non-seizure load) reaches 90 kg, and the PD value (sintering load) reaches 126 kg, far exceeding the industry's basic standard (the PB value of ordinary additives is usually 60-80 kg), which is a direct manifestation of the value of scientific formulation design.

Supplier of Hydraulic Oil Additives Package
UNPChemicals is a professional supplier of high-quality and effective Hydraulic Oil Additives Package. We offer several remarkable products, namely High zinc hydraulic oil additives UNP AH502A,Low Zinc Hydraulic Oil Additives UNP AH502B,Zinc-free Hydraulic Oil Additives UNP AH502C,etc.
High zinc hydraulic oil additives UNP AH502A are a type of chemical additive used in hydraulic oils that contain high levels of zinc dialkyldithiophosphate (ZDDP). ZDDP is a well-known anti-wear agent that also provides antioxidant, anti-corrosion, and anti-foam properties. The zinc in these additives plays a crucial role in forming a protective film on metal surfaces within the hydraulic system, thereby reducing wear and extending the life of the system components.
Low Zinc Hydraulic Oil Additives UNP AH502B are a class of advanced lubricant additives designed to enhance the performance of hydraulic oils with reduced zinc content.These additives are formulated to provide a balance of anti-wear,extreme pressure,and antioxidant properties,making them suitable for modern hydraulic systems that demand high performance with lower environmental impact.
Zinc-free Hydraulic Oil Additives UNP AH502C are a new class of environmentally friendly lubricant additives designed for hydraulic systems.These additives are formulated to provide the same level of performance as traditional zinc-containing additives but without the heavy metal content,reducing the environmental impact of hydraulic fluids.
