Capacitors

Borclean™ are a family of the purest polypropylene homopolymers for capacitor film manufacturing. These polymers are produced with ultra
low levels of impurities and residues and extreme care is exercised to avoid any risk of contamination.

Our polypropylene homopolymers for capacitor film offers the best
possible dielectric film properties, resulting in high and consistent breakdown strengths and low dielectric losses.

Borclean for capacitor film makes the difference

Borclean product grades are widened and enhanced by a revolutionary type of high isotactic homopolymer. The isotacticity of more than 98 % offers BOPP manufacturers films with improved mechanical properties at elevated temperatures, meaning higher stiffness and lower shrinkage. As a result, the polymers further deliver improved dielectrical properties and less deterioration of the film winding at higher service temperatures of the capacitor.

Capacitor film produced using Borclean  polypropylene grades offers:

• Super high purity,
• Ultra low ash level,
• Low dissipation factor,
• Maximum cleanliness.

All products delivered by Borealis are tailored in relation to molecular weight and molecular weight distribution to maximise processability. These balanced rheological properties as well as the extreme low gel content ensure smooth processing behaviour, as well as extrusion and stretching.
