LSI Chemical’s ArcticArmor 523 is a cold flow improver for diesel fuels to improve low-temperature performance and greatly improve winter operability. It is engineered to improve multiple characteristics of diesel, including Cold Filter Plugging Point (CFPP), Pour Point, and Cloud Point for today’s modern diesel fuels and typical biodiesel blends and is recommended for all diesel engines. The DFPP test demonstrated an improvement when compared to Marathon baseline diesel from -20°F/-28°C to -45°F/-42°C. The Pour Point improved from -20°F/-28°C to -75°F/-59°C, the company stated. Cloud point is lowered by solubilizing paraffin nuclei as they begin to crystallize, and the pour point depressants modify paraffin crystal’s growth as they precipitate.
