Electrical insulation is of paramount importance for the correct functioning of electrical equipment.  Power hardware cannot function without energy losses, which lead to rises in temperature.  It is critical to remove the heat to prevent failure of the equipment.  When circulated, specific liquids can dissipate heat.

There are benefits of using polybutenes instead of mineral oils when formulating insulating oils.  For example: the structure and grade of the mineral oil can vary depending on the origin of the crude oil from which the mineral oil was derived, whereas polybutenes are synthetic substances, and consequently their properties are within a very narrow specification range.

Polybutene is typically used in cable jelly compounds, cable insulation materials and cable oils.  Butyl rubber plasticised with KEMAT Polybutenes can also be used as an electrical insulator combined with a flame retardant.  KEMAT’s portfolio offers the widest range of molecular weights (MW) on the market to match any need in formulation in the field of electrical insulating oils.
