Fuel anti-foam agents are additives used to prevent foam formation in fuel systems. They enhance fuel efficiency by reducing air entrainment and improving combustion. These agents are crucial for maintaining smooth operation in aviation, automotive, and marine engines.

Key specifications and technical properties of Fuel Anti-Foam Agents and Fuel Systems:

Size: Typically available in liquid form with container sizes ranging from 1-liter bottles to bulk drums (200L).

Grade: Aviation-grade (e.g., MIL-A-8243) or automotive-grade (e.g., ASTM D4171).

Viscosity: Low to medium viscosity (5–50 cSt at 40°C) for easy dispersion in fuel.

Buoyancy: Non-buoyant; designed to mix uniformly with fuel without separation.

Material: Silicone-based polymers (e.g., polydimethylsiloxane) or organic polyglycols.

Dosage: Typically 1–10 ppm (parts per million) in fuel systems.

Operating Temperature: -40°C to 150°C for aviation and industrial applications.

Compatibility: Compatible with jet fuels (JP-8, Jet A-1), diesel, and gasoline.

Flash Point: >100°C to ensure safety in fuel handling.

Density: 0.85–1.1 g/cm³, similar to hydrocarbon fuels.

Chemical Stability: Resistant to oxidation and degradation in fuel systems.
