Capacitor Oil and Heat Transfer Oil for Electrical Equipment
Electric insulation and capacitor oils PXE and PEPE, and DBT heat transfer oil.
The equipment specification decides which fluid is accepted. BASTONE supplies PXE and PEPE insulating oils and DBT heat transfer oil with datasheet and lot COA.

What kind of oil is used in capacitors?
Capacitors use dielectric oils such as PXE (phenyl xylyl ethane) and PEPE (phenylethyl phenylethane), which BASTONE lists as capacitor oil.
What is the difference between PXE and PEPE oil?
Both are listed as electric insulation, capacitor and dielectric oils. PEPE is also listed as a low-temperature insulating oil. Ask for datasheet values that match your design.
Is DBT a dielectric oil or a heat transfer fluid?
DBT is sold as heat transfer oil and conducting oil, and the site lists it with dielectric oils. State your application so the datasheet matches the use.
Need a grade that is not listed?
Send the resin or chemical you use today, the application and your monthly volume. BASTONE replies with matching grades, COA documents and a quote.
