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.
