Commercial 585

Commercial 585
 UL File No. E343348 
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.
