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)
- 45b 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. This recipe also skips on Phthalic Acid, thus not needing Naphthalene any longer.

- Benzene
- Phenol
- Carbon Monoxide
- Ammonia
- Oxygen
- PBI
- Water
Uses of PBI¶
