Raw Rubber is the unprocessed polymer item at the start of Ala Industrial's oil chain. The Polymerizer produces one Raw Rubber from 1000 mB of oil — a full Oil Bucket — plus 400 EU, drawing 2 EU per tick over 200 ticks at the LV tier (low voltage, up to 32 EU/tick). It is the most affordable way to turn pumped oil into a crafting ingredient, so every oil lake you drain eventually feeds Raw Rubber into storage.

Raw Rubber is only an intermediate, not a finished material: it cannot be smelted in a furnace, and the vanilla smelting shortcut was removed. To complete the chain, load Raw Rubber into a Vulcanizer with four Sulfur Dust and external heat — a campfire yields one Rubber, lava or magma yields two, and an Electric Heater yields three. Finished Rubber then insulates the mod's cables and opens the path into the MV tier. As a fallback, the Incubator can duplicate Raw Rubber at a high EU cost. Raw Rubber is an item rather than a placeable block, stacks to 64, and behaves identically on Fabric and NeoForge for Minecraft 26.2 (Java Edition).
