Overview
Pertinax (HP 2061) is a phenolic paper laminate — the most economical technical laminate. Good mechanical and electrical properties for low voltage applications. Excellent machinability and punching quality up to 2.5 mm thickness. Used for electrical panels, terminal boards and low-voltage insulation.
MATERIAL DESIGNATION
Reading the HP 2061 designation
HP 2061 is the Pertinax designation used for this family. The named supplier grade VOLTIS® HP 2061 is a PF CP 201 phenolic-paper laminate to IEC 60893: PF = phenolic resin, CP = cellulosic paper, and 201 = the standard construction / classification. HP TU 21 is a separate rolled tube product within the same family; always confirm the required grade and form.
