Fuel Pour Point Depressants are additives that lower the temperature at which fuel solidifies, ensuring smooth flow in cold conditions. They work by modifying wax crystal formation in fuels like diesel and aviation fuel. Fuel Systems utilize these depressants to maintain optimal performance and prevent clogging in low-temperature environments.

Key specifications and technical properties of Fuel Pour Point Depressants (PPDs) and Fuel Systems:

Size: Typically supplied in liquid form, with container sizes ranging from 1-liter bottles to bulk tankers (20,000+ liters).

Grade: Varies by application (e.g., diesel, jet fuel, marine fuels); common grades include ASTM D97-compliant for diesel and ISO 3016 for aviation fuels.

Viscosity: Typically low to moderate (5–50 cSt at 40°C), ensuring easy blending with fuels.

Buoyancy: Not applicable in liquid form; solid variants (if any) are denser than water (SG ~0.8–1.1).

Material: Polymer-based (e.g., ethylene-vinyl acetate copolymers, alkylated naphthalenes, or polymethacrylates).

Operating Temperature: Effective down to -40°C, depending on fuel type and concentration.

Dosage: Typically 0.01–0.1% by volume, varying with fuel composition.

Compatibility: Compatible with most hydrocarbon fuels and additives; non-corrosive to metals (steel, aluminum).

Flash Point: >60°C, ensuring safe handling and storage.

Storage: Stable under ambient conditions; avoid prolonged exposure to sunlight or extreme heat.
