CHARACTERISTICS OF A GOOD HI-PERFORMANCE HYDRAULIC FLUID

CHARACTERISTIC
DESCRIPTION
GREENPLUS HYDRAULIC FLUID ES
Viscosity Thickness or resistance to flow; must be suited to system design Most equipment manufacturers will specify a viscosity range for proper operation. Greenplus will meet or exceed those specified limits.
Viscosity vs. Temperature Variation of viscosity with temperature (viscosity Index); must be minimal viscosity change with temperature change Greenplus has less variations with temperature change. Greenplus acts as a multi-viscosity oil. Maintains a stable viscosity through a wide operating temperature range.
Storage Capability Minimal change in storage or use Greenplus shelf life is good, maintaining its characteristics indefinitely.
Lubricity Film formation and friction reduction Greenplus has an affinity for metal and a reluctance to run off. Excellent film is maintained with our higher Viscosity Index (239).
Metal Compatibility Minimal effect, physically and chemically, on metals, seals, gaskets and hoses Vegetable based lubricants are known for their compatibility with seals, gaskets and hoses. Greenplus is even better because of natural additives.
Heat Transfer Capability High specific heat and thermal conductivity to dissipate heat Users typically report excellent heat transfer performance, equal or superior to petroleum products.
Compressibility Low compressibility Greenplus is non-compressible.
Volatility Minimal evaporation and bubble formation to reduce fluid loss and cavitation Greenplus has a very high flash point (279°C) and is very difficult to vaporize.
Forming Tendency Foam or entrained air increases compressibility Non-petroleum defoamer additive keeps fluid free of air entrainment and eliminates foaming.
Toxicity Meets or exceeds regulatory and safety standards affecting workers and the environment. Greenplus is safe for workers compared with petroleum. Environmental bio assay of LC50>10,000 ppm in a spill. Not considered a toxic oil under US OPA 90.
Environmental Compatibility Minimal effect on the environment as the result of an accidental spill or disposal. Reflected in government legislation which allows treatment of vegetable oil lubricants as less environmentally dangerous than petroleum and synthetics in a spill situation.
