There are rubber trees in swamp land. There you find yellow points (sticky resin). You can harvest the sticky resin with a treetab. Then you have to put it into an oven or extractor.

There is also another kind of rubber, also not black, which is rubber used to make rubber bars. But this kind is not obtainable in TekketLite, because the MineFactory Rubber Trees are not enabled here.
