Methyl Phenyl Silicone Oil 500cst CAS 63148-58-3 High Temperature Dielectric Fluid for Transformer
500cst Methyl Phenyl Silicone Oil (CAS 63148-58-3) is transparent methyl phenyl modified polysiloxane fluid. The phenyl structure greatly improves high temperature stability compared with ordinary dimethyl silicone oil. It acts as special dielectric insulating fluid for transformers. It possesses reliable dielectric property, efficient heat transfer capacity and long-term oxidation resistance. It insulates electrical components and dissipates operational heat, suitable for high-temperature worki
Product Overview
500cst Methyl Phenyl Silicone Oil (CAS 63148-58-3) is synthetic methyl phenyl polysiloxane. Phenyl groups are introduced into the silicone molecular chain to enhance high-temperature oxidation resistance and dielectric stability. Medium-high viscosity provides balanced heat conduction and sealing performance. This silicone fluid is developed as dielectric cooling and insulating medium for dry-type transformers, power transformers and other high-temperature electrical equipment. It isolates charged components and transfers heat to avoid local overheating failure.
Key Features
- Excellent electrical insulation performance, stable dielectric strength
- Superior high-temperature thermal oxidation stability, long service cycle
- Efficient heat transfer and heat dissipation capability
- Low volatility, low vapor pressure, less medium consumption
- Chemically inert, non-corrosive to copper, aluminum and metal winding materials
Main Applications
- Dielectric insulating & cooling fluid for high temperature transformers
- Insulating medium for power electrical and electronic equipment
- Heat dissipation silicone liquid for high voltage electrical modules
- Dielectric fluid for high-temperature power distribution components
Usage Guidance
Used in closed transformer cooling and insulation systems. Avoid long-term direct contact with air under extreme high temperature to extend service life. Strictly prevent mixing with mineral transformer oil, acidic and alkaline substances. Regularly test dielectric strength and replace when performance declines.
Storage & Package
Keep drums tightly sealed. Store in cool, dry and ventilated warehouse. Stay away from open flame, high temperature and strong oxidants. Standard package: 25kg plastic drum, 200kg iron drum. Shelf life: 12 months under proper storage conditions.
Service Support
Test samples are available for electrical performance testing. Stable bulk supply and technical consultation for electrical manufacturers. Welcome to obtain TDS, COA and competitive factory quotation。
