APICAL® Polyimide CR
Type CR Polyimide Film
APICAL® Polyimide Film Is the Right Choice.
APICAL® Corona Resistant Polyimide 110CR and L50CR11 are high temperature Polyimide Films. These CR films have excellent thermal and electrical stability over the long life of any motor.
APICAL® 110CR and L50CR11 is designed to withstand the compounding conditions and form strong interfacial bonding with many materials. The polymer will remain stable during extended high temperature continuous use conditions.
- Excellent thermal and electrical stability
- Excellent adhesion to copper
- Excellent corona resistant stability

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.
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.
