Silicone Rubber
Silicone Rubber is a flexible crafted material in Subnautica 2, made from Quartz and used in many essential early-game tools.
Quick Info
Description
Silicone Rubber is one of the first crafted materials you'll make in Subnautica 2. Its flexibility and durability make it a go-to component for tools that need grip, sealing, or shock absorption. Because it only requires Quartz, you can start producing it almost immediately after collecting a few outcrops.
How to Craft
Silicone Rubber is crafted at the Fabricator using Quartz. No special prerequisites or blueprints are required beyond the default Fabricator recipes.
Quartz
1x — found in shale outcrops at 0–200m.
Fabricator
Crafting station found in lifepods and bases.
Prerequisites
None — available from the start.
