Rubber

Rubber is a refined resource used in crafting and automation chains. It is produced in a Chemistry Lab and is one of the materials required for several mid-tier items, though the specific recipes vary and are not always listed alongside the material itself.

Rubber can be made from either Resin or Organic, giving it a flexible production path. With Organic, a Tapper can be attached to any tappable flora to generate a steady supply, which makes Rubber effectively cost only one Resin in practice when that route is used. The Organic output can then be moved into a Chemistry Lab with an Auto Arm. With Resin, Rubber can be produced more directly by keeping Resin storage on the same platform as the Chemistry Lab, or by supplying Resin from Auto Extractors.

This makes Rubber useful both as a crafting ingredient and as a product that can be scaled up through automation. The Tapper-based method is especially efficient because it turns common flora into a renewable feedstock, while the Resin method is simpler when a base already has reliable Resin production.
