Tribological Qualities, Properties, and Features
Proven Leader In Fluid Stability
Stability is what defines a premium quality hydraulic fluid. Stability is the most notable quality of United Bio Lube's Bio MIL-PRF-32073 Hydraulic Fluid (Grade 3) - ISO 32 made from Stabilized2 HOBS1 and Bio Corrosion Inhibitor (BCI™) chemistries.
The overall stability of United Bio Lube's Bio MIL-PRF-32073 Hydraulic Fluid (Grade 3) - ISO 32 is a function of four main qualities: Oxidation Stability, Mechanical Shear Stability, Hydrolytic Stability, and Combustion Stability.
|
Made from Stabilized2 HOBS1, Bio MIL-PRF-32073 Hydraulic Fluid (Grade 3) - ISO 32 shows performance improvements over petroleum in nearly all physical properties:
Superior Lubricity
United Bio Lube's Bio MIL-PRF-32073 Hydraulic Fluid (Grade 3) - ISO 32 is formulated to outperform petroleum based products. The natural Fluid Film of this high viscosity fluid has proven in laboratory and field tests to outperform petroleum fluids in terms of Lubricity.
Greater lubricity leads to:
- Less Wear
- Less Energy Consumption
- Lower Operating Temperatures
Oxidation Stability
Oxidation Stability is the most important quality affecting Operation and Service Life of Bio MIL-PRF-32073 Hydraulic Fluid (Grade 3) - ISO 32. The properties of any type of hydraulic fluid can be expected to change with time. Factors most influencing change include:
- Mechanical Stress and Cavitation, which can break down and reduced fluid Viscosity.
- Oxidation and Hydrolysis which cause:
- Chemical Changes
- Formation of Volatile Components
- Insoluble Materials
- Corrosive Products
Patented Stabilized2 High Oleic Base Stocks (HOBS)1 technology keeps Bio MIL-PRF-32073 Hydraulic Fluid (Grade 3) - ISO 32 from breaking down and forming Acidic Residues harmful to rubber seals, gaskets, and other elastomers.
Bench tests measuring Oxidation Stability
indicate United Bio Lube's Bio MIL-PRF-32073 Hydraulic Fluid (Grade 3) - ISO 32 is superior in comparision with the leading petroleum based
Synthetic brands, non-stabilized Commercial Vegetable Oils (i.e. Rapeseed, Canola, Soy), and Mineral Oils in
terms of the longest PDSC time of 90 minutes and the lowest Acid Number < 0.4 in the industry.
Enhanced chemical stability prevents the formation of varnish deposits and thickening of gums and sludge.
Superior ASTM D6186, "Standard Test Method for Oxidation Induction Time of Lubricating Oils by Pressure Differential Scanning Calorimetry (PDSC)"
Superior Oxidation Stability is measured by ASTM D-6183 testing methods, yielding a PDSC time of 90 minutes!
PDSC testing validates patented Stabilized High Oleic Base Stocks (HOBS) technology naturally prevents oxidation from occurring in Bio Hydraulic Fluid formulas. Stabilized technology provides Bio Hydraulic Fluid formulas with an extremely high resistance to chemical breakdown, or Thermal Degradation.
Neutralization Number
ASTM D-974, "Standard Test Method for Acid and Base Number by Color-Indicator Titration" is another method used to measure Oxidation Stability.
Acid Neutralization Number measuring less than 0.4 for United Bio Lube's Bio MIL-PRF-32073 Hydraulic Fluid (Grade 3) - ISO 32 is one of the lowest in the industry!
Super High Viscosity Index
Natural Fluid Film Strength prevents viscosity breakdown under high-shear conditions.
The super high shear stable Viscosity Index = 184 of Bio MIL-PRF-32073 Hydraulic Fluid (Grade 3) - ISO 32 made from
Stabilized High Oleic Base Stocks (HOBS) naturally provides very high Fluid Film strength yielding superior Lubricity,
Load Carrying Capacity, and Mechanical Shear characteristics for optimum protection of all critical gears,
bearings, and components.
The shear stable Viscosity Index allows pumps to be safely started at low ambient temperatures where the flow properties of conventional straight grade petroleum based hydraulic fluids often cause problems. The high Viscosity Index of Stabilized HOBS improves operating reliability over a wide range of pump output pressures.
The high Viscosity Index (i.e. VI = 184) reduces friction between moving parts resulting in less heat generated. Less Heat means Less Energy Consumption and Lower Risk of Leaks.
Conversely, at higher operating temperatures, the high Viscosity Index maintains the proper Viscosity required to minimize internal pump Leakage and Wear.
Note: High shear rates and turbulent flow conditions often present in hydraulic systems can quickly destroy the molecular bonds
of petroleum based hydraulic fluids (Mineral Oil, Synthetic, Synthetic Blends). Over time, this degradation results in loss of viscosity.
Extreme Temperature Protection
United Bio Lube's Bio MIL-PRF-32073 Hydraulic Fluid (Grade 3) - ISO 32 withstands high and low temperature variations and swings.
Cold Fluid Temperature Reliability
A very low Pour Point = -40 °C, -40 °F and improved low temperature fluidity
both contribute to improved Energy Efficiency.
Patented Stabilized technology incorporates advanced Cold Flow
properties to maintain fluidity for improved cold temperature Starting and Pumpability.
High Fluid Temperature Reliability
Bio MIL-PRF-32073 Hydraulic Fluid (Grade 3) - ISO 32 is engineered for long term, High Temperature operation.
The higher Flash Point = 236 °C, 456.8 °F, superior Viscosity Index, and greater Oxidation Stability allow this fluid to function in very high
temperatures without breaking down and reducing viscosity.
Note: Petroleum-based hydraulic fluid temperatures above 180 °F will damage most seal compounds and accelerate degradation of fluid. When temperatures are too high, the fluid's viscosity drops below the required value and the hydraulic system's components begin to wear due to inadequate lubrication as a result of excessive thinning of the lubricating Fluid Film.
Patented Stabilized2 chemistry maintains Shear Stability, Oxidation Stability, and
Fluid Film thickness at extremely high temperatures and Fluidity and cold flow Pumpability at severely low temperatures.
Anti-Wear (AW) - Extreme Pressure (EP) Protection
The purpose of Anti-Wear additives is to maintain lubrication during conditions of Boundary Lubrication.
A Zinc-free additive package provides Anti-Wear (AW) - Extreme Pressure (EP) performance protects critical gears, bearings, and components
from Wear and Fatigue. System components remain protected from wear and fatigue while operating under
heavy loads in rugged service.
Very High Load Carrying Capacity
Anti-Wear (AW) and very high Load Carrying Capacity characteristics combine to reduce
Pitting and Scoring without hurting any of the soft Yellow metals often found in hydraulic pumps.
The combination of Lubricity, Anti-Oxidation, and Load Carrying Capacity protects metal pump bearings,
gears, and other components from Scuffing, Galling, Scoring, Scratching, Pitting, and Fatigue.
United Bio Lube's Bio MIL-PRF-32073 Hydraulic Fluid (Grade 3) - ISO 32 meets and exceeds major Original Equipment manufacturers (OEMs) hydraulic pump Anti-Wear protection requirements. Anti-Wear (AW) additives have been
thoroughly Tested and Qualified against the most stringent and demanding Military and Industrial hydraulic fluid standards.

made from Stabilized HOBS, truly outperforms conventional petroleum hydraulic fluids in Accelerated 4-Ball EP Wear Tests
measuring Load Carrying Capacity.
Natural Lubricity and Load Carrying Capacity combine to keep machinery and equipment
in top working condition while operating under heavy loads, extreme temperatures, and high pressures.
Resistance Against Foaming
United Bio Lube's Bio MIL-PRF-32073 Hydraulic Fluid (Grade 3) - ISO 32 resists foaming and Air Entrainment through the use of Anti-Foam agents. Anti-Foam agents are surface-active chemicals designed to prevent foam by lowering the surface tension of air bubbles. This change in surface tension causes air bubbles to either collapse or rupture.
Anti-Foaming and Air Release properties make Bio MIL-PRF-32073 Hydraulic Fluid (Grade 3) - ISO 32 highly resistant to Foaming, Aeration and Cavitation; thereby eliminating Sponginess and Fading hydraulic system responses.
Anti-Foaming additives prevent Reservoir Overflow, Overheating, and Contact between adjacent metal surfaces.
In addition to preventing Foaming, Aeration and Cavitation, United Bio Lube's Bio MIL-PRF-32073 Hydraulic Fluid (Grade 3) - ISO 32 prevents many other common problems due to Foaming:
- Increased machine operating temperatures
- Inadequate lubrication due to reduced fluid flow
- Loss of Fluid Film between mating surfaces

- Increased gear and bearing noise
- Erratic operation
Bio MIL-PRF-32073 Hydraulic Fluid (Grade 3) - ISO 32 passes the ASTM D 892, "Foaming Characteristics of Lubricating Fluids" test method with Zero Foam.
Note: Abnormal noise in hydraulic systems is often caused by Aeration or Cavitation.
Bio Corrosion Inhibitors (BCI™)
Patented Bio Corrosion Inhibitors (BCI™) effectively inhibit both the corrosion of Yellow metals and rusting of Ferrous metals.
Bio MIL-PRF-32073 Hydraulic Fluid (Grade 3) - ISO 32 with BCI™ chemistry prevents corrosion and rust from occurring on the surface of metals in both Fresh Water and Salt Water environments.
Bio MIL-PRF-32073 Hydraulic Fluid (Grade 3) - ISO 32 with BCI™ chemistry meets and exceeds U.S. Military Anti-Rust and Anti-Oxidation requirements for hydraulic systems used in all types of military, industrial, and farming machinery and equipment.
Anti-Corrosion and Anti-Rust protection reduces formation of deposits on the surface of metal parts and components.
No other competitive lubricant company has this advanced BCI™ technology offering.
Anti-Rust Protection
Rust is a chemical reaction between water and ferrous metals.
Bio MIL-PRF-32073 Hydraulic Fluid (Grade 3) - ISO 32 prevents rusting in both Fresh & Salt water environments. This is demonstrated by passing results in both A & B sequences of the ASTM D 665, "Turbine Oil Rust Test".
Anti-Corrosion Protection
Corrosion is a chemical reaction between chemicals, usually acids, and yellow metals. There are many types of industrial hydraulic systems that have parts made of Non-Ferrous, or Yellow metals, i.e. Copper, Brass or Bronze.
BCI™ chemistry prevents acids and other corrosive agents from reacting with the metal surfaces of non-ferrous Yellow metals.
BCI™ is not chemically reactive to Yellow metals as demonstrated by the ASTM D 130, "Copper Strip Corrosion Test".
Water Resistant
Superior Hydrolytic Stability
Highly resistant to moisture, United Bio Lube's Bio MIL-PRF-32073 Hydraulic Fluid (Grade 3) - ISO 32 with Bio Corrosion Inhibitors (BCI™) exhibits
excellent Hydrolytic Stability in the presence of water.
Bio MIL-PRF-32073 Hydraulic Fluid (Grade 3) - ISO 32 has the ability to Emulsify water and Suspend and Disperse other
contaminants, i.e. Gum, Varnish, and Sludge, thereby preventing the formation of Deposits on metal surfaces. Components remain free from
harmful, deteriorating deposits.
To boost Hydrolytic Stability, Bio MIL-PRF-32073 Hydraulic Fluid (Grade 3) - ISO 32 with BCI™ chemistry
is compounded with Demulsifiers, Detergents, and Dispersants. Demulsibility properties
readily separate out water from the fluid. Collectively, these safe additive agents act to inhibit the formation of Rust and Corrosion
while enhancing fluid Filterability.
Superior Hydrolytic Stability prevents damage to Pumps, Hydraulic Valves, Actuators,
and the Circulating System operating in humid or wet climates.
Note: Water contamination of hydraulic fluids accelerates the aging of the fluid, reduces
Lubricity, Filterability, and Seal Life, and leads to Corrosion and Cavitation. At high temperatures,
emulsified water can be turned into 'Steam' at the contact points of highly loaded parts in the system.
Seal Conditioning
Bio MIL-PRF-32073 Hydraulic Fluid (Grade 3) - ISO 32 is formulated to provide Seal Conditioning for Longer Seal Life and to Reduce Fluid Leakage from the system.
Combustion Stability
Extremely Low Volatility
The extremely Low Volatility of Stabilized HOBS increases the Flash Point and Fire Point safety features of Bio MIL-PRF-32073 Hydraulic Fluid (Grade 3) - ISO 32.
Low Volatility prevents surface molecules from vaporizing into exhaust air. Noticeably, there is no Off-Gassing of harmful toxic vapors when working near or handling these safe, biodegradable fluids.
United Bio Lube's Bio MIL-PRF-32073 Hydraulic Fluid (Grade 3) - ISO 32 do not contain and will not Off-Gas any harmful fumes, including Volatile Organic Compounds (VOCs), Phenols, or Chlorides.
Extremely low Volatility leads to:
