For professionals in the electrical and chemical industries, a deep understanding of technical specifications is crucial when sourcing critical materials like insulating oils. Monobenzyl Toluene and Dibenzyl Toluene (M/DBT) insulating oil is a high-performance dielectric fluid widely used in the manufacture of high-voltage power capacitors. As a leading manufacturer and supplier of these specialized chemicals from China, we aim to provide clarity on the technical parameters that make our M/DBT insulating oil an exceptional choice for your industrial needs. When you are ready to buy, knowing these details will help you make an informed decision.

The performance of a capacitor is directly influenced by the quality of its insulating fluid. M/DBT insulating oil is engineered to deliver superior insulation and thermal stability. Its chemical composition, primarily Monobenzyl Toluene and Dibenzyl Toluene, results in excellent dielectric properties, including a high breakdown voltage and a low dielectric loss. These attributes are essential for preventing electrical breakdown and minimizing energy dissipation within the capacitor, thereby enhancing its efficiency and lifespan. For R&D scientists and product formulators, procuring this specialized oil from a reputable China-based manufacturer ensures consistent quality.

Let's delve into the key technical specifications commonly referenced for M/DBT insulating oil, adhering to standards like GB 21221-2007. The appearance is typically described as a colorless transparent liquid, ensuring visual confirmation of purity. Critical electrical properties include a high electric volume resistivity (e.g., ≥ 1.0*10¹² Ω.m at 90°C), indicating excellent insulating capability, and a low dielectric dissipation factor (tan δ ≤ 0.001 at 90°C), minimizing electrical losses. The relative permittivity (εγ) typically ranges between 2.45-2.55 at 90°C, a factor in capacitor design. Procurement managers seeking to buy this material will find these figures vital for application suitability.

Beyond electrical properties, physical characteristics are equally important. The density (0.980-1.020 g/cm³ at 20°C) and kinetic viscosity (≤ 4.0 mm²/s at 40°C) influence its flow characteristics and heat transfer capabilities. The low pour point (≤ -60°C) is particularly noteworthy, signifying its excellent performance in cold climates, a significant advantage for many applications. The acid number (≤ 0.015 mg KOH/g) highlights its chemical stability and low corrosivity.
