As evident by the flowchart, PBI is one of the more complex plastics to make. Don't worry, it only gets worse from here on.
Do note however, the I/O in this flowchart has been balanced. You can make PBI with far less materials, you would just have leftover ingredients.
- 38b Naphthalene
- 2x Potassium Dust
- 90b Phenol (45 if you recycle)
- 67.5b Sulfuric Acid (135 without distillation, 153 if you store Hydrogen Sulfide for SPT boosting)
- 72b Oxygen (if you recycle Hydrogen Sulfide)
- 90b Nitric Acid
- 180b Chlorine
- 90b Benzene
- 90b Hydrogen
- 5x Copper Dust
- 90b Ammonia
- 45.45b PBI
- 45b Phenol (without recycling)
- 180b Hydrochloric Acid
- 135b Diluted Sulfuric Acid (You should really distill this)
Chem Plant
Thankfully, with the help of the Chem Plant, you can skip that long chemical line, and condense it into 1 recipe.
Chem Plant
Thankfully, with the help of the Chem Plant, you can skip that long chemical line, and condense it into 1 recipe. This recipe also skips on Phthalic Acid, thus not needing Naphthalene any longer.

Inputs are Benzene, Phenol, Carbon Monoxide, Ammonia, and Oxygen. You can just void Water.
Uses of PBI
You will need it as a sheet to make both
