| UL File No.: |
E48013 |
| ASTM Spec: |
ASTM D-710, Commercial |
| Military Spec: |
Mil-F-1148, C-H; Mil-F-13526, Red Sheet |
| NEMA Grade: |
Commercial |
Properties
High mechanical & dielectric strength. Good shock absorbing & wear resisting
qualities. Excellent punching, forming, & turning characteristics. Semi-hard & has
a good surface finish.
Applications
A general purpose mechanical & electrical grade normally recommended where a
special requirement is not indicated. High dielectric strength & unusual mechanical
strength afford a broad application base. Typical applications include washers,
insulating plates, arc barriers, switch & appliance insulation, terminal block
covers, coil spool heads & formed parts. |
Thickness Range
