Benefits
|
| Cast Film |
- Thin gauge PTFE film
- Uniform tensile properties in both machine and traverse direction
- Isotropic shrinkage as a function of temperature
|
| Multilayer |
- High degree of consolidation resulting in superior dielectric performance
- Pigments and other additives may be added to individual layers to customize performance
|
| PTFE |
- Superior performance in a wide range of chemical, thermal and electrical environments
|
| Slitting |
- Available in slit widths to 1", supplied in pad rolls; minimum quantities apply
