Metallized Polypropylene Film Series

Characteristic:

We use imported ultra-high purity electrical-grade polypropylene resin as raw material, implementing flat-film method of two-way stretch, with good thickness uniformity, high compressive strength, dielectric loss, easy rolling and other excellent physical and electrical properties. With a variety of capacitor impregnated oil compatibility, the National Power Capacitor Test Center proves our products are perfectly in line with the performance of the power capacitor insulation media.
