Rubber

Rubber is a mid-game item refined from Crude Oil commonly used for alternative recipes and some late-game items.

Alternate recipes analysis
The following shows different ways to produce 1 Rubber / second, or 60 / min:
 * Weighted Point is the weighted consumption rate which is calculated by: . The lower the better.
 * Energy per item can be used to measure how much power is consumed for the entire production chain. The lower the better.
 * Space refers to building space, excluding belts and pipes. The lower the better.
 * Energy can be recovered in some recipes, by first producing Residual Fuel then burn it in Fuel Generators. The leftover energy can be used to power other factory buildings.
 * The most efficient production route involves several recipes as shown in the above diagram. If Blender is not yet unlocked, Diluted Packaged Fuel can be used instead, with slightly more power consumption.

Tips
Later in the game when you have collected the majority of the Hard Drives, be sure to unlock the following Alternate Recipes: Combine these with Packaged Water, Unpackage Fuel, and Residual Rubber to form a closed-loop production of Plastic and/or Rubber without any wastage, increasing the Oil to Plastic/Rubber conversion ratio up to 1:3. Empty Canisters from fuel unpackaging are reused and recycled back to the water packaging.
