Isomeric alcohol ether phosphate ester PMET PE1690

Description

What is Isomeric alcohol ether phosphate ester PMET PE1690?

Isomeric alcohol ether phosphate ester PMET PE1690 is a multi-functional sulfur-free phosphorus-containing lubricant additive built on optimized branched isomeric alcohol ether phosphate molecular framework. This liquid additive integrates extreme pressure anti-wear, friction adjustment, metal wetting and rust-proof performance all in one, featuring balanced monoester and diester composite structure to deliver stable boundary lubrication effect under heavy-load friction conditions. It can rapidly generate dense phosphate tribofilms on steel, aluminum, copper and alloy contact surfaces, cutting metal direct contact and abrasion loss effectively. PMET PE1690 mixes uniformly with mineral base oils, synthetic ester oils and polyalphaolefin base stocks, and is widely blended into industrial circulating lubricants, neat metalworking oils, heavy-duty gear fluids and multi-purpose greases to lift bearing, gear and cutting tool service life while stabilizing whole system lubricating performance.

Features of Isomeric alcohol ether phosphate ester PMET PE1690

PMET PE1690 carries multiple exclusive structural strengths that distinguish it from common linear alkyl phosphate ester additives:

Branched Isomeric Alkyl Structure & Excellent Universal Solubility

The branched isomeric alcohol ether side chain eliminates precipitation and stratification issues seen in straight-chain phosphate products. It achieves full miscibility in low-viscosity mineral oil, PAO and synthetic ester base fluids, maintains uniform single-phase state under low-temperature storage and long static standing, and simplifies dosing and blending procedures during lubricant production.

Strong Extreme Pressure & Rapid Tribofilm Formation

Under high contact pressure and instantaneous sliding friction, the active phosphorus groups of PMET PE1690 quickly react with fresh metal surfaces to build continuous, tough phosphate protective films. The film bears heavy impact loads and avoids surface scratching, scoring and seizure for gears, sliding bearings and cutting workpieces under harsh working conditions.

Balanced Friction Modulation & Polishing Effect

Unlike single extreme pressure phosphate additives that only resist wear, PMET PE1690 delivers moderate friction reduction capacity. It smooths micro-protrusions on machined metal surfaces during cutting, grinding and forming procedures, upgrading workpiece surface finish and lowering friction heat buildup at contact zones.

Wide Metal Compatibility & Mild Anti-Corrosion Performance

It works well with ferrous metal, aluminum alloy, brass and copper components without triggering discoloration or pitting corrosion on yellow metals. The adsorbed film isolates metal substrates from water traces and acidic oxidation byproducts in oil, providing basic rust prevention during equipment standby periods.

Good Synergy with Other Lubricant Additives

PMET PE1690 can be compounded with ashless friction modifiers, aminic antioxidants and metal passivators without flocculation or performance offset. It does not interfere with core functions of other additives in finished oil formulas, offering flexible matching space for formulators to adjust additive packages freely.

Stable Thermal Performance & Low Volatility

Modified ether-linked molecular structure lifts thermal decomposition temperature, retaining steady extreme pressure and anti-wear activity under continuous working temperature up to 150°C. Volatilization loss is minimal during long-cycle high-temperature operation, avoiding rapid performance attenuation of lubricants in heat-intensive equipment.

Functions of Isomeric alcohol ether phosphate ester PMET PE1690

As a composite phosphate ester multi-functional additive, PMET PE1690 undertakes four core functional roles in lubricant formulations:

Extreme Pressure Anti-Wear & Anti-Seize Protection

When metal contact surfaces bear heavy loads and thin oil film breakdown occurs, PMET PE1690 reacts with metal to form solid phosphate tribofilms. The film bears shear and impact force to stop direct metal-to-metal contact, eliminating scoring, pitting and seizure failures of moving mechanical parts.

Friction Coefficient Adjustment & Heat Reduction

It optimizes boundary friction coefficient between metal friction pairs, lowering friction resistance and heat generation during operation. Less heat accumulation slows base oil thermal aging and reduces thermal deformation risk of precision components.

Metal Surface Wetting & Machining Brightening

In metalworking oil systems, PMET PE1690 penetrates evenly into narrow cutting gaps between tool and workpiece. It smooths micro burrs and uneven textures generated by cutting abrasion, improving surface smoothness of finished parts and extending cutting tool service cycle.

Light Metal Passivation & Rust Suppression

A thin adsorption barrier forms on all metal surfaces immersed in lubricant, blocking contact between metal and trace moisture, acidic substances inside oil. It suppresses surface oxidation and rust formation during equipment shutdown and intermittent operation.

Applications of Isomeric alcohol ether phosphate ester PMET PE1690

Relying on its integrated extreme pressure, anti-wear and friction adjustment capacity, PMET PE1690 fits a wide range of mechanical lubrication and metal processing product lines:

Heavy-Duty Industrial Gear Oils

Suitable for closed industrial gearboxes, worm gears and reduction units with heavy shock loads. It protects gear tooth surfaces from scoring and wear under variable high loads, extending gear overhaul intervals and stabilizing transmission efficiency.

Straight Oil Metalworking Fluids

Blended into cutting oils, grinding oils, aluminum rolling oils and cold forming oils. It delivers excellent lubrication during high-speed cutting, precision grinding and metal stamping, lowering tool wear and raising surface quality of steel, aluminum and copper workpieces.

Circulating Industrial Lubricants & Hydraulic Oils

Added into high-load circulating turbine oils, compressor oils and industrial hydraulic fluids. It safeguards pump valve core, sliding bearing and piston friction pairs under continuous circulation, reducing internal component abrasion and cutting down equipment maintenance frequency.

Multi-Purpose Heavy-Duty Greases

Incorporated into lithium complex grease, aluminum complex grease and open gear bearing greases. It sustains stable extreme pressure lubrication for bearings operating under heavy load and moderate temperature, avoiding grease lubrication failure caused by metal wear.

Synthetic Base Lubricants

Compatible with PAO, synthetic ester and polyglycol fully synthetic lubricants for high-temperature chain oil and transmission fluids. It compensates insufficient boundary lubrication performance of pure synthetic base stocks without damaging original oil stability.

Price of Isomeric alcohol ether phosphate ester PMET PE1690

The market price of Isomeric alcohol ether phosphate ester PMET PE1690 fluctuates dynamically, affected by raw material supply status, bulk order quantity, international chemical raw material price swings and regional logistics expenses. For latest real-time quotations, bulk preferential policies and formula dosage reference data, lubricant formulators and manufacturers are advised to reach out to professional additive suppliers directly to get customized cost solutions.
