Key specifications and technical properties of Fuel Biofuel Compatibility Additives and Fuel Systems:
Size: Varies by application (typically 1L to 208L containers for additives; fuel system components range from small fittings to large tanks).
Grade: ASTM D975, EN 590, or equivalent for diesel compatibility; ASTM D7467 for biodiesel blends (B6-B20).
Viscosity: 1.5–5.0 cSt at 40°C (additives); fuel systems designed for 1.3–4.1 cSt (biodiesel blends).
Buoyancy: Neutral buoyancy in fuel (additives); fuel system materials selected to prevent floatation issues.
Material: Additives: synthetic hydrocarbons, esters; Fuel systems: stainless steel, aluminum, or coated polymers (e.g., HDPE, PTFE).
Compatibility: Resistant to oxidation, hydrolysis, and microbial growth in biofuel blends.
Operating Temperature: -30°C to +80°C (additives); -40°C to +120°C (fuel system components).
Density: 0.85–0.90 g/cm³ (additives); matches fuel density (systems).
Flash Point: >60°C (additives); >52°C (fuel systems).
pH: 6–8 (additives to prevent corrosion).
