Polyimide (PI)¶
Guide by: ME Item Storage Cell
PI is the most advanced plastic used to insulate cables, used in conjunction with PVC and PPS. You will need it from
In case you were wondering, it is pronounced close to pol-yimide, not poly-mide, or
poly-imide.

About as long as the other plastics you would be making at this tier. The only real difference is the use of Chem Plants. You could forgo them, but it would make the recipe tree much longer.

Uses of PI¶
As mentioned before, PI is used as a foil to insulate cables in addition to PVC and PPS. You will first need it to make Europium Cable, used in
PI is the last plastic you need to insulate cables, for the rest of the game (for now, that is).
