It is found in nature, but at the same time it can encompass the Plastic theme. Plastic can give amazing out-of-the-box ideas that reference the real world. Plastic can hardly be digested or decompose, and the soil/water are full of it. Now, imagine an Aron-like creature that eats plastic and forms a shell out of soil and plastic !
Since Plastic can vary a lot in its properties, naming the type Rubber immediately gives you a point of reference. This is a type that blocks electricity and melts easily. Finally! a type that counters Electric that makes sense.
Rubber can also function as a counterpart to Steel. Another "Artificial" type, but it resists Fighting and Electric.
