Composition / Chemistry

	Composition / Chemistry
	Your choices are...
	Straight Oil (Non-soluble)		Straight oils are non-emulsifiable products used in machining operations in an undiluted form. They are composed of base mineral or petroleum oils and often contain polar lubricants such as fats, vegetable oils, and esters, as well as extreme pressure additives such as chlorine, sulfur, and phosphorus. Straight oils provide the best lubrication and the poorest cooling characteristics among cutting fluids.
	Water Soluble / Emulsion		Water-soluble and emulsion fluids have a high dilution or very low concentration. They include high water content fluids (HWCF). Soluble oil fluids form an emulsion when mixed with water. The concentrate consists of a base mineral oil and emulsifiers to help produce a stable emulsion. These fluids are used in a diluted form with concentrations ranging from 3% to 10%, and provide good lubrication and heat transfer performance. They are used widely in industry and are the least expensive among all cutting fluids.  Water-soluble fluids are used as water-in-oil emulsions or oil-water-emulsions. Water-in-oil emulsions have a continuous phase of oil and superior lubricating and friction reduction qualities (i.e., metal forming and drawing). Oil-in-water emulsions consist of droplets of oil in a continuous water phase and have better cooling characteristics (i.e., metal cutting fluids and grinding coolants).
	Synthetic / Semi-synthetic		Synthetic or semi-synthetic fluids or greases are based on synthetic compounds, such as silicone, polyglycol, esters, diesters, chlorofluorocarbons (CFCs), and mixtures of synthetic fluids and water. Synthetic fluids tend to have the highest fire resistance and cost. They contain no petroleum or mineral oil base, but are instead formulated from alkaline organic and inorganic compounds along with additives for corrosion inhibition. Synthetic fluids are generally used in a diluted form with concentrations ranging from 3% to 10%. They often provide the best cooling performance among all cutting fluids. Some synthetics, such as phosphate esters, react or dissolve paint, pipe thread compounds, and electrical insulation. Semi-synthetic fluids are essentially combinations of synthetic and soluble petroleum or mineral oil fluids. The characteristics, cost, and heat transfer performance of semi-synthetic fluids fall between those of synthetic and soluble oil fluids.
	Micro-dispersion		Oil or lubricating fluids contain a dispersion of solid lubricant particles such as PTFE (Teflon®), graphite, and molybdenum disulfide or boron nitride in a mineral, petroleum, or synthetic oil base. Teflon is a registered trademark of DuPont.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
	Chemistry / Constituents:
	Your choices are...
	Petroleum / Mineral Oil		Products contain petroleum or mineral oil constituents, such as fluids and greases. Straight oils are mineral or petroleum oils that do not have added water.
	Silicone		Products contain silicone-based greases, oils, or fluids. Silicone fluids are synthetic and provide outstanding thermal and dielectric properties.
	Polyglycol / Water-Glycol		Polyglycol, glycol, and water-glycol fluids are synthetics often used for anti-freeze circulating, coolant, and high water content fluid (HWCF) hydraulic applications. Water-glycol solutions tend to have higher viscosity index values than other compositions.  Zinc, cadmium, and magnesium react with water-glycol solutions and should not be used in fluid or coolant systems that contain water-glycol fluids.
	Fluoropolymer / PTFE (e.g., Teflon®)		Fluoropolymer solid lubricants include polytetrafluoroethylene (PTFE) and are available in various forms such as powder for dispersion into other fluids or liquid lubricants; sprayable coatings, or solid machinable shapes (e.g., sheets, films, tubes). Teflon®, a registered trademark of DuPont, consists of PTFE.
	Natural (Vegetable Oil / Animal Fat)		Fluids, lubricants, or greases are based on natural vegetable or plant oils or animal fats. Vegetable and plant-based products, such as soybean oils, are a renewable resource and an attractive alternative to mineral oils and synthetic fluids. Some natural oils pose fewer risks to workers and have a reduced environmental impact.
	Specialty / Other		Other unlisted or specialized chemistries.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Properties

	Density / Specific Gravity (@15.6°C, 60°F):		Specific gravity is density normalized to water or another standard. Density is the mass per unit volume of a material.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
	Kinematic Viscosity (@ 40°C)		Kinematic viscosity is the time required for a fixed amount of fluid or oil to flow through a capillary tube under the force of gravity.  Units of kinematic viscosity are stoke, centistoke (1/100 of a stoke) and Saybolt Universal Seconds (SUS). Saybolt Universal Seconds or Saybolt Universal Viscosity (SUV) is the time in seconds required for 60 cubic centimeters of a fluid to flow through the orifice of the standard Saybolt universal viscometer at a given temperature under specified conditions, usually per ASTM D 88.  Kinematic viscosity is also described as the quotient of the absolute viscosity in centipoises divided by the specific gravity of a fluid where both are measured at the same temperature.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
	Pour Point		Pour point is the lowest point that fluid or oil flows. Pour is typically determined using ASTM D 97. Generally, the pour point is 15° F to 20° F below the system's lowest end-use temperature to prevent pump damage through cavitation.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

Features

	Features
	Your choices are...
	Anti-knock Agent		Anti-knock agents reduce engine pinging or knocking caused by premature ignition. Anti-knock fuel additives include lead (i.e., tetra-ethyl lead, use discontinued), methylcyclopentadienyl manganese tricarbonyl (MMT), ferrocene, iron pentacarbonyl, toluene, and isooctane. Lead was phased out because of issues with toxicity and damage to catalytic converters.  Aromatic hydrocarbons, ethers and alcohol (usually ethanol or methanol) are also added to fuel to reduce knocking.
	Biodegradable		Biodegradable products are designed or suitable to decompose or break down into harmless chemicals when released into the environment.
	Cetane / Octane Booster		Cetane boosters increase the cetane number of diesel fuels. The cetane number indicates the combustion quality of a diesel fuel during compression ignition.  2-ethylhexyl nitrate (2EHN) dimethyl ether, alkyl nitrates, and di-tert-butyl peroxide are common cetane index improvers. Octane boosters increase the octane rating number of gasoline.  The octane rating is the resistance of petrol and other fuels to auto ignite a spark plug combustion engine. A gasoline composition containing 90% iso-octane and 10% heptane would have an octane rating of 90. MTBE, ETBE, isooctane and toluene are common octane boosters.
	EP (Extreme Pressure / Active)		Extra pressure (EP) additives include chemically active agents such as sulfur, phosphorous, or chlorinated compounds that are reactive and form a film to prevent seizure, sticking or surface adhesion under loads causing high pressure conditions.
	Low / Non-foaming		Fluids do not produce foam or produce only small amounts of foam. Non-foaming characteristics are achieved through the use of additives that break out entrained air. Leaks can introduce air into systems for circulating hydraulic fluid, thermal oil, or grinding coolant. Entrained air can cause pump damage due to cavitation. Foaming can also reduce the cooling ability and the bulk modulus (or stiffness) of the fluid.
	Microbe Inhibiting / Biocide		Lubricants, greases, coolants, heater oils, or fluids have an inherent composition or biocide additives that inhibit the growth of bacteria, fungus, or other microbes.  Without biological growth inhibition, water emulsions or water-based fluids can develop a strong odor under certain conditions. Biocides or antimicrobial pesticides are chemical agents used to kill microbiological organisms such as bacteria or fungi in fluids.
	Oxidation Inhibiting		Lubricants, greases, coolants, heater oils, or fluids have oxidation inhibiting additives or an inherently oxidation resistant compositions.
	Passivator / Metal Deactivator		Lubricants, greases, coolants, heater oils, or fluids have passivating or metal deactivating additives. Passivators or deactivators are used in coolants, lubricants, metalworking, or heat transfer fluids, passivate internal or machined surfaces.
	Sealing / Barrier		Products are designed for or providing sealing or barrier functions.
	System Cleaner / Sludge Dispersing		System cleaners, sludge dispersing fluids, or detergent oils are lubricating oils or fluids with special sludge dispersing or cleaning properties. They usually incorporate special additives. Detergent oils suspend formed sludge or dirt particles and thus promote the cleanliness of internal surfaces, especially in internal-combustion engines. The sludge particles are removed from the system by oil filters or when the oil is drained and changed. Special system cleaners are available for carbon residue cleaning of internal surfaces in circulating heat transfer systems.
	Water Displacement		Water displacement lubricants or fluids have the ability to displace water from a surface based on wetting or surface energy characteristics. Fluids with low surface energy or interfacial tension compared to water will flow under the water or moisture on a surface.
