Two Tests:Primary Vs. Ultimate

Biodegradation

Biodegradation Reaction:

Lubricant CH+ O2 + Bugs CO2 + H2O + More Bugs (Biomass)

Primary Biodegradation Ultimate BiodegradationCEC L-33- A 93 OECD 301, ASTM D 5864, ASTM D7373 > 80% >60%

Types of Biodegradability Readily Biodegradable Hydraulic Fluids

Break Down Over 80% in 21 Days – 60% in 28 Days

Inherently Biodegradable Products Break Down… Someday … after fines, cleanup, downtime and environmental destruction!

Inherently Biodegradable

• Not Truly Biodegradable• Expensive for petroleum

Conventional Vegetable FluidsHETG

Oxidative WeaknessTemperature limitationsLife expectancy

Hydrolytic WeaknessCare must be taken

Polyglycol Synthetic (PAG)

• Fire Resistant• Specifically Designed System• Not Compatible with Petroleum or Vegetable

Synthetic Esters (HEES)• Hydrolytic Unstable

– “unzips” with water

• Acid formation• Seal Deterioration

Ester ChemistryVegetable Oil + Alcohol + Acid

Synthetic Ester + Water + Heat

Bio-polyolefin Synthetic (HEPR)

• Durable• Low Cost/Long Fluid Life• Separates From Water• Good Seal Compatibility• Broad Temperature Range

ApplicationClass Typical

PerformanceSeal & Hose Compatibility

Limitations Application

HETGEL 100

Varies Mixed Medium Water, Heat Light Duty, Short change out, low temperature.

HEPGEL FR 46

Weak Very Poor Miscible Incompatible with many seal materials. Absorbs moisture. Prices vary

Fire hazard, especially designed system

HEESEL 2000

Mixed Very Poor Very Weak

Hydrolyzes in water. Creates acids. Expensive.

If dry, high performance.

HEPREL 3000EL 200

Excellent Excellent Excellent Expensive Heavy duty, chance of contamination

ConclusionsMaking the determination to change to bio

lubricants one should consider many factorsA bio oil can be more expensive initially but

can save money in the long termBio oils have been proven in the field and can

perform as well as petroleum
