Sasol HF-1000 Solvent

Sasol HF-1000 Solvent is a synthetic blend of paraffins, olefins, and oxygenates. It is a pale yellow, oily liquid with a medium flash point and a mild odor. HF-1000 Solvent is an alternative to diesel-based fluids and highly branched isoparaffinic mineral oils, which have low acute aquatic toxicity, rapid biodegradation, and the absence of polynuclear aromatics.

Aerobic Biodegradation

Biodegradation tests run in accordance with OECD 301-F guidelines show that the HF-1000 Solvent will exhibit >60% degradation by day 28. When tested together, the HF-1000 Solvent shows a more rapid and extensive biodegradation than the #2 diesel fuel.

Further Storage Information

Small quantities should be stored in sealed bottles, totes and drums at a temperature of 25°C (77°F) or less. Liquid bulk quantities should be padded with a dry inert gas, such as nitrogen, to prevent air from entering the tank or container. The product should not be exposed to temperatures in excess of 60°C (140°F) for long periods of time to avoid product degradation. Based on our experience, HF-1000 Solvent shows no physical and/or chemical changes for at least 36 months after the manufacturing date when stored under conditions that minimize exposure to air, moisture and extreme temperatures. It is recommended to test the solvent for key specifications every 36 months after the manufacturing date.
