Fuel lubricity additives enhance the lubricating properties of fuels to reduce wear in fuel system components. They are essential for low-sulfur diesel and biodiesel blends that lack natural lubricity. These additives help protect fuel pumps, injectors, and other critical parts from premature failure.

Key specifications and technical properties of Fuel Lubricity Additives and Fuel Systems:

- Size: Typically available in liquid form with particle sizes ranging from 1-100 microns for solid additives.

- Grade: Industrial, automotive, marine, or aviation grades depending on application.

- Viscosity: Varies from 1-500 cSt (centistokes) at 40°C, depending on formulation.

- Buoyancy: Generally not applicable as most additives are liquid or soluble in fuel.

- Material: Commonly composed of esters, fatty acids, or synthetic compounds.

- Flash Point: Typically above 60°C to ensure safe handling.

- Density: Ranges from 0.8-1.2 g/cm³, depending on chemical composition.

- Solubility: Fully soluble in diesel, biodiesel, or other hydrocarbon fuels.

- Concentration: Used in ppm (parts per million) levels, usually 100-500 ppm.

- Compatibility: Compatible with elastomers, metals, and fuel system components.

- Pour Point: Typically below -20°C to ensure cold-weather performance.

- Sulfur Content: Often ultra-low (<10 ppm) to meet environmental regulations.
