AMS3303 Silicone
AMS3303 silicone is a widely used aerospace‑grade silicone rubber defined by SAE International. It specifies a general‑purpose, 60‑durometer solid silicone suitable for demanding environments where long‑term heat resistance, weatherability, and stability in petroleum‑based lubricating oils are required.
ElastaPro manufactures AMS3303‑compliant silicone sheet and uncured compound, delivering consistent performance for aerospace, industrial, and high‑temperature sealing applications. We also make other AMS silicone materials.
What Is AMS3303 Silicone?
AMS3303 is an AMS (Aerospace Material Specification) covering solid silicone rubber in the form of:
- Sheets
- Strips
- Tubing
- Extrusions
- Molded shapes
This solid silicone is formulated from MQ/VMQ silicone rubber and engineered for reliable performance across a wide temperature range and in environments where exposure to lubricating oils and outdoor conditions is expected.
