Quality
Industries who depend upon APICAL® Polyimide Film benefit not only from a carefully designed product, but from the process behind it as well. Unlike many film manufacturers, APICAL® Polyimide process technology is driven by quality not speed.
Performance
In spite of being lighter in weight than many of the materials it has replaced, the overall performance of APICAL® Polyimide surpasses them. Its high degree of dimensional stability allows it to be wrapped tightly for applications where space is a premium. It is tough, highly resistant to tearing, abrasion and puncture.
