Product Details

The DA-PM series comprises high-temperature-resistant insulating silicone oils, with methylphenyl polysiloxane as the principal component. These products exhibit outstanding stability, low volatility, superior dielectric properties, radiation resistance, chemical inertness, and excellent low-temperature fluidity. The incorporation of a high phenyl content in the molecular chain significantly enhances thermal stability, enabling long-term service at temperatures below 300°C. Compared with dimethyl silicone oil grades, the DA-PM series offers superior high-temperature and radiation resistance, maintaining excellent insulation and lubrication under conditions of high temperature, heavy load, and intense radiation. Key applications include impregnation for power capacitors, high-voltage insulating oils, cooling and insulation in nuclear power equipment, low-temperature hydraulic damping fluids, radiation-resistant lubricants, and moisture-proof insulation for precision instruments.
