PLURASAFE®PAG WS, WI, WT Fluids

PLURASAFE® Fluids

PLURASAFE®PAG fluids are polyalkylene glycol derivatives that cover a broad range of viscosities and solubilities. Variations in molecular weight, alkylene oxide or ratios of alkylene oxides produce a wide variety of fluids with differing properties. In general, they are chemically and thermally stable: they have low pour points and are not corrosive to metal.

Nomenclature

The letters WS, WI and WT mean water-soluble, water insoluble and water thickening. The number following the designation refers to the approximate viscosity in Saybolt Universal Seconds (SUS) at 38° C (100°F).

Applications

Lubricants - When properly formulated, PLURASFE®PAG fluids are excellent high temperature, compressor, gear, rubber, textile, fiber, mill and calendar lubricants.

Hydraulic Fluids - PLURASAFE®PAG fluids can be used unblended as hydraulic fluids for boundary lubrication and low temperature applications or formulated with water and additives for wear and corrosion protection.

PLURASAFE®PAG fluids have many specialized uses, including chemical intermediates, defoamers, demulsifiers, plasticizers and solvents for both inks and dyes.

Blending

Two PLURASFE®PAG fluids can be blended to obtain a fluid of intermediate viscosity. When blending, it is preferable to use two products with viscosities close to the viscosity desired.

To obtain the percent of the lower viscosity fluid required for blending, the following equation should be used:

%L = ( log Vh - log Vd / log Vh - log Vl ) x 100

Where:

Vl = Viscosity at 38°C of the lower viscosity fluid (SUS)

Vh = Viscosity at 38°C of the higher viscosity fluid (SUS)

Vd = Viscosity desired (SUS)

L = Fluid with lower viscosity
