What is Chlorosulfonated (Hypalon rubber) Sheet?
Chlorosulfonated, commercially popular as Hypalon rubber, is a synthetic rubber sheet. The name Hypalon was originally registered by the American chemical company DuPont. It is a high-performance rubber designed for the harshest and extreme industrial environments, where standard elastomers might fail.
Hypalon rubber sheeting offers a balance of chemical resilience and physical strength. It is parallelly immune to UV degradation and Ozone cracking. Therefore, Hypalon sheets make an excellent choice for marine and outdoor applications. Hypalon gaskets provide a superior barrier against oxidizing agents like Nitric and Sulfuric acid. Since it comes in smooth textures on both sides, users choose it for static and dynamic sealing and lining functions.
- Chemical tank linings
- Lining in flue gas and exhaust systems
- Weatherproof expansion joints
- Acid barrier curtains and more
