As record-breaking heatwaves push 5G base stations and EV charging piles to their thermal limits, conventional coolants—often thick and prone to low flash points—struggle with flow dead zones and safety risks. IOTA’s new low-viscosity ethyl silicone oil, IOTA 20570, flips the script. This colorless, odorless polymethylethylsiloxane has a viscosity of just 4–4.5 cps at 25°C, roughly one-tenth that of standard silicone heat-transfer fluids, dramatically improving heat transfer. With a flash point above 145°C and a pour point below -90°C, it stays steady from blistering summers to freezing winters, giving outdoor electronics a wider “thermal shield.” Unlike mineral-oil-based alternatives, IOTA 20570 hardly reacts with strong acids or alkalis (excluding concentrated sulfuric and hydrofluoric acid), offering greater chemical inertness and longer lifespan. Its excellent dielectric properties also allow direct cooling of high-power radio equipment, cutting leakage hazards. As extreme-heat red alerts become routine, industrial cooling is shifting from simply lowering temperatures to delivering safe, long-lasting performance. IOTA Organosilicon’s low-viscosity, high-flash-point combo provides a more reliable solution for data centers and new-energy systems alike. Packed in 200 L or 1000 L drums, shelf life 24 months.
