EUROTHERM 350 AND MARLOTHERM SH COMPARISON AS SYNTHETIC HEAT TRANSFER FLUIDS
Chemie Eurotherm 350
Product Description：
High-temperature synthetic thermal oil, colorless and odorless, features a very low pour point and kinematic viscosity. Its chemical composition consists of high-purity single aromatic hydrocarbon compounds. The unique chemical structure imparts excellent low-temperature flow properties and high-temperature thermal stability, ensuring a long expected service life. With an extremely high atmospheric boiling point, it guarantees low operating pressure for heating systems at high temperatures, making it safe and reliable. Additionally, it is recyclable, energy-efficient, and environmentally friendly, representing a sustainable choice for high-temperature synthetic thermal oils.
Recommended Application Temperature：-30～350℃
