For professionals in the electrical and electronics manufacturing sector, understanding the precise technical specifications of raw materials is critical for ensuring product quality and performance. Phenyl Xylyl Ethane (PXE) oil, a specialized dielectric fluid, plays a vital role in the construction of high-performance capacitors. As a leading manufacturer and supplier of this essential chemical from China, we are committed to providing transparent and comprehensive product data to aid your decision-making process. If you are looking to buy PXE insulating oil, understanding its key specifications is the first step.

Decoding the Technical Data for PXE Insulating Oil

The efficacy of PXE oil (CAS 6196-95-8) as a capacitor impregnating agent and dielectric insulator is defined by a range of physical and electrical properties. These parameters dictate its suitability for specific capacitor designs and operating conditions. Here’s a breakdown of the critical specifications:

  • Appearance: Typically described as a colorless to pale yellow transparent liquid, indicating its purity and lack of significant impurities or degradation.
  • Density (20°C): Ranging from 0.970 to 0.990 g/cm³, this property is important for calculating fill volumes and understanding the oil's physical behavior.
  • Acid Number: A low acid number (≤0.015 mg KOH/g) signifies minimal acidity, which is crucial for preventing corrosion of capacitor components and maintaining the oil's dielectric integrity.
  • Flash Point: A high flash point (≥140°C) indicates reduced flammability, enhancing safety during handling, storage, and operation.
  • Pour Point: A low pour point (≤-40°C) ensures that the oil remains fluid and functional even at very low temperatures, vital for applications in cold climates.
  • Kinetic Viscosity (40°C): With a viscosity of ≤7.0 mm²/s, PXE oil offers a balance suitable for effective impregnation of capacitor windings and films.
  • Breakdown Voltage: A high breakdown voltage (≥70 kV) is a testament to its excellent electrical insulation capabilities, protecting the capacitor from electrical breakdown.
  • Dielectric Dissipation Factor (90°C, 50Hz): A very low factor (≤0.001) indicates minimal energy loss as heat when subjected to an electric field, which is crucial for capacitor efficiency.
  • Electric Volume Resistivity (90°C): An exceptionally high resistivity (≥1.0*10¹² Ω.m) demonstrates its superior ability to resist current flow, a fundamental requirement for dielectric materials.
  • Relative Permittivity (90°C, 50Hz): The permittivity value (2.40-2.50) is important for calculating capacitance and understanding the dielectric constant of the material.
  • Water Content: A low water content (≤50 mg/kg) is essential, as moisture significantly degrades the dielectric properties of insulating oils.
  • Gassing Property: A negative gassing property (e.g., ≤-100 m³/min) indicates the oil's tendency to absorb gases under electrical stress rather than releasing them, contributing to internal stability.
