Polytetrafluoroethylene, henceforth "PTFE" is a material required for you to craft many items in the mid and late stages of the pack, including Atomic Alloy which you will require already in the HV stage. But the journey to setting up a PTFE factory is long and arduous, requiring many steps. You will need: HV GameStage 1x Mekanism Thermal Evaporation Plant 1x Resistive Heater (to heat the TEP as solars are disabled Water Source (Aqueous Accumulator is fine, if surrounded by water) 1x Pyrolyse Oven Wood farm to supply Pyrolyse Oven Min. 1x Fluorine Chicken Min. 1x Gassy Chicken 5x GT Chemical Reactors (Min. 1x HV, the rest can be LV+) 1x GT Distillery (MV+) 2x GT Centrifuge (Min. 1x MV, other can be LV+) 1x GT Electrolyzer (LV+) Below is a flowchart of which machines connect to eachother Some machines will output more than one thing in this chain. Be sure to store some in a barrel or drum before voiding! You might require it in the future!
