1. Similar to PPI 1091 and 10912 but with two or more parallel
strips of copper.
2. Similar to PPI 1091, 10912, 1095 and 1096 but with a wide
range of film thicknesses and other insulating materials such
as Polyimide film, PEN film and NOMEX®2.

3. Special shapes and die-cut pieces of copper insulated in the
same way as PPI 1091, 10912, 1095 and 1096 and available in a
range of copper thicknesses up to 0,150 mm (6 Mils).
4. Copper foils with insulation laminated on one side only for
coil winding.

Polyester thickness

Insulation for classes B, F and H available as standard.
Static shielding in forms other than those described above can
be produced subject to minimum order requirements.
For further information please consult our “PPI foils for shielding
and winding” catalogue.

The copper is partially wrapped with the polyester leaving a
minimum 1 mm = 0,04” wide strip of uncovered copper in the
middle of one side. The minimum overlap of polyester required
on each edge of the uncovered strip of the copper is as follows:
polyester 0,025 mm = 1,0 Mil
polyester 0,050 mm = 2,0 Mil
Tolerence on width polyester 0,025 mm = 1,0 Mil
polyester 0,050 mm = 2,0 Mil

3 mm = 0,12”
4 mm = 0,16”

+ 0,3 mm = + 0.012”
+ 0,5 mm = + 0,20”

Available width polyester 0,025 mm = 1,0 Mil
from 7 mm to 100 mm = from 0,28” to 4”
polyester 0,050 mm = 2,0 Mil
from 9 mm to 100 mm = from 0,36” to 4”
Roll length: up to 100 m = 110 yds
*Other copper thicknesses may be supplied subject to availability and minimum order
requirements.
