Commercial 585
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
0.005" to 4"
Note - Thickness over 0.102" is
Laminated Built-Up Fibre.

Color
Grey, Black, Red
