IOTA 250-30 Methyl Phenyl Silicone Oil – Precision Performance for Extreme Conditions
When reliability meets versatility, the IOTA 250-30 Methyl Phenyl Silicone Oil stands out as a high-performance fluid engineered for demanding applications. With its unique poly(methylphenylsiloxane) backbone, this specialty silicone oil delivers an exceptional balance of thermal stability, electrical insulation, and low-temperature fluidity – making it a trusted choice across industries from power electronics to healthcare.
Key Technical Highlights:
Viscosity (25°C): 25–40 cSt – ideal for low-viscosity, high-penetration applications.
Refractive Index (25°C): 1.4700–1.4800 – ensures optical clarity.
Relative Density (25°C): 1.010–1.080 – lightweight yet robust.
Flash Point (open cup): ≥240°C – safe for high-temperature operations.
Freezing Point: –45°C – remains fluid even in sub-zero environments.
This silicone oil excels where others fail. Its low pour point, high flash point, low thermal expansion coefficient, and outstanding dielectric strength (high corona resistance and average breakdown voltage) make it the preferred impregnating fluid for large power capacitors. Beyond electrical applications, IOTA 250-30 is also used as a non-stick release additive for plasma bags and infusion tubing, a base oil for surgical ointments, and a smooth-feel ingredient in cosmetics and skincare formulations.
Storage & Handling:
Supplied in 25 kg, 50 kg plastic drums, or 200 kg steel drums. Store in a dry, cool warehouse away from direct sunlight (allowable ambient temperature: –40 to 50°C). Classified as non-hazardous for transport and storage. Shelf life: 3 years under recommended conditions.
Brand: IOTA – synonymous with quality silicone innovation.
