MPP Capacitors

Metallized Polypropylene is a major raw material in a Capacitor and sets the quality standards of the Capacitor. Therefore a careful selection of quality Metallized Film is vital in the performance of Capacitors.

At Tibrewala, a combination of best BOPP Film (PHD from Trespaphan), latest machinery and Quality Management Systems result in High Quality Metallized Films. Some of the best Capacitor companies around the world buy TIBCON FILM.

Customers can choose a width between 15-110 mm and an Outer diameter between 230-330mm Zinc Alloy Metallized Films. We also offer series Metallized Film for High Voltage applications.

Capacitors made of TIBCON FILM have high voltage strength and a low loss factor tan δ of 2x10-4. Due to a very low water absorption of < 0,1 %, even rather thin metal layers are stable.

Depending on the capacitor design, high operation temperatures of 100°C and more can be achieved.

Shortly we will introduce Pure Aluminum, Segmented Film and Taper Heavy Edge Technology.
