IOTA 2056 PES Polyethylsiloxane fluids, identified by CAS No. 63148-61-8, represent a specialized class of synthetic oligomeric fluids with a linear polyethylsiloxane structure. These fluids stand out due to their unique combination of physical and chemical properties, enabling diverse and demanding industrial applications.

Characterized as colorless, odorless, chemically inert, non-toxic, and explosion-proof, IOTA 2056 PES fluids offer exceptional operational stability. Key technical properties include outstanding low-temperature performance, with a solidifying point below -70°C, ensuring functionality in extreme cold. They exhibit excellent lubricity and full compatibility with both mineral and synthetic oils. Two primary viscosity grades are available: IOTA 2056 PES-1 (34-40 mm²/s at 25°C) and IOTA 2056 PES-2 (180-280 mm²/s at 25°C), differing also in density (0.95-0.98 g/cm³ vs. 0.99-1.02 g/cm³) and flash point (>170°C vs. >265°C). Both share a low acid value (<0.1 KOH mg/g), a refractive index of 1.44, and solubility in aromatic/chlorinated hydrocarbons while being insoluble in water and lower alcohols.

Their property profile translates into significant industrial utility:

• Extreme Environment Lubrication & Hydraulics: Serving as hydraulic fluids, instrument lubricating oils, and low-temperature base oils, they ensure stable operation of mechanisms and instruments from -70°C up to +150°C. Good dielectric properties make them suitable for electro-mechanisms.

• Chemistry & Petrochemistry: They act as a reinforcing agent for fibers in tire cord manufacturing, improving tire quality. Functioning as release agents and modifiers in molding materials (e.g., glass-reinforced plastic), anti-dust additives in pigments, plasticizers in rubber products, and bases for greases and release emulsions is common. They also serve as effective heat transfer fluids (150-200°C in open systems, 180-250°C in closed systems).

• Cosmetics: Utilized as a base for creams and as an additive in lipsticks and mascaras, leveraging their inertness and smooth texture.

In summary, IOTA 2056 PES Polyethylsiloxane fluids provide a critical blend of extreme temperature resilience, inertness, lubricity, and compatibility. Available in tailored viscosity grades, they deliver reliable performance solutions across demanding sectors from heavy industry and energy to advanced materials and personal care, particularly where low-temperature operation or high thermal stability is paramount.
